A simple, crank-mounted, electrical system powers the airplane and the ignition from a permanent-magnet alternator, much like modern motorcycles do. Save my name, email, and website in this browser for the next time I comment. My bike was flawless, as one would expect. by Pete Twissell » Tue Oct 10, 2017 12:48 pm "cruise today was 100 kts at 27,500 rpm" That’s great, but the trick is the needle attached to the slide. marcusofcotton. Take the top off any Jabiru-powered airplane and prepare to be dazzled. Description The J230-D is the flagship LSA model in a long lineage of Jabiru aircraft. It could be you! The timing is fixed at 25 degrees. Engine failure? Granted, it could be hard to argue an engine failed because of the oil, but it would be easy to argue one failed because an oil vastly different from that recommended by the manufacturer was used. That may be a part that is physically bolted to the engine during its manufacturing process or a manufacturer’s specific oil or oil filter recommendation. (Still, carburetor heat is a recommended airframe addition. An expensive recovery mission was needed and a summer of barnstorming ended for lack of routine maintenance. 403 hours and climbing. The Jabiru 3300 is a six-cylinder direct-drive air-cooled aircraft engine from Jabiru Aircraft Pty. Jabiru 3300 - Reassembly - Re-fitting The Cylinder Heads. Pilot Operating Handbook All of them and none of them. Jabiru is a reputable manufacturer of engines and aircraft. Any engine that boasts a fleet of successful, flying installations can be deemed “reliable.”. I will go out on a limb and say that most “high CHT” issues are related to cowling and cooling baffle installations, not the engine itself. This is an understandable question. This air-cooled engine is in an engine test cell where it is kept cool with a custom baffle that forces the prop wash through the cylinders. With the low-end LSAs becoming modern darlings, Jabiru could be well placed. A poor installation can shorten the life of the most reliable engine core. If you have any questions or doubts about the contents, please contact Jabiru Aircraft P/L. A Continental O-200 has a 3.88-inch stroke, for comparison. Nice touch. This is simply due to the fact that reliability … Your engine may operate in a different part of the green arc than your friend’s identical engine on an identical airframe but that is not an indication of trouble, it is the nature of engines and homebuilts. This is common on air-cooled engines with solid lifters. marcusofcotton. The damage done, however, when dry piston rings are explosively compressed against corroding cylinder walls is immediate and cumulative. Exhaust, Carburetor, Starter Motor, Alternator & Ignition System & Accessory pack. A carbureted Lycoming can do … This full throttle break-in is done in the air, not on the ground, so the engine cools properly. Home: CO15. The temperatures displayed on this EFIS range from 32 to 59 degrees, yet this aircraft had been sitting in a heated hangar, undisturbed, for weeks. These pages serve purely as an informational archive. To keep costs down, Jabiru uses off-the-shelf automotive parts where it can. Fleet hours and units in service are a great yard-stick for reliability but every engine design begins with a single unit and a handful of hours. That 3.3-liter displacement is 201 cubic inches, making this a great comparison with the Continental O-200. Some days the best thing you can do for your engine is leave it in the hangar. Runup is conventional but short: Check the ignition and glance at the gauges. When you cross paths with someone complaining about the engine problems they’ve had, trace your eyes down the airframe it’s mated to. Motor Head #16: Jabiru — A New Engine That’s Not All That... United, Archer Partner On Short-Haul Electric Aircraft, Re.Invent Air Mobility Initiative Participants Selected, How A Split Second Wrong Decision Caused the Kobe Bryant Fatal…, How This Illustration Fueled My Obsession With The Bell X-1, EAA Posts Initial AirVenture 2021 Health And Safety Measures, Sriwijaya Air Prelim Highlights Thrust Imbalance, FAA Investigating Latest SpaceX Starship Test, Rolls-Royce Conducts Unblended SAF Tests On BizJet Engine, Report Calls For Multi-Pathway Approach To Mitigating Aviation Lead, Avionics: Down For 2020 But Showing Signs of Recovery, Wireless Utility Controls Jammed GPS Near Airport, uAvionix Launches pingStation 2 ADS-B Receiver. KOSH x 5 Flying a B-Model Conversion (Super Bee Baby!) Therefore, we must fly in a manner that lessens the consequences of an engine failure. Home: CO15. New engine designs are always coming to market. Yes, an engine’s reliability begins at the design and manufacturing level (more on that later) but their ongoing dependability relies on how well they are installed, broken in, operated, maintained, and how often they are flown. Given a choice, who wouldn’t put the most reliable engine on their aircraft? We must accept that no engine is completely reliable and that we, as installers, operators, and maintainers, bear much of the responsibility for this. Which engine is the most reliable? My experience with the 912 is that the system works as advertised but EGTs inevitably drop at altitude, hurting fuel efficiency. Questionable instrument indications can often present themselves when an engine is placed into service but these can usually be traced to a defective sender, poor wire connection, or an incorrectly programmed instrument. Got motors on your mind? Broken valve train? In fact, you could see the Jabiru as the new product of an existing engine company leveraging its knowledge of traditional designs, only making the engine smaller and lighter. KOSH x 5 Flying a B-Model Conversion (Super Bee Baby!) Every engine has operating limitations that define its maximum and minimum operating temperatures and pressures. Also note that I don't own any Jabiru products, engine or airframe soI have no stake in what is said. Learn how your comment data is processed. When performing maintenance remain aware of what parts have been touched by hands and tools—both purposely and accidentally—in the course of maintenance and always perform a post-maintenance inspection and test flight. Our brand new CNC lathe is bolted down and working and a brand new CNC horizontal machining centre is on order and will be delivered at the end of March. During the approach and landing, the engine is extremely well behaved, and the ability to basically ignore it and fly the airplane is wonderful. The Continental is two inches longer than the six-cylinder Jabiru, nearly five inches taller, and almost nine inches wider. flybymike wrote:For my retirement present to myself I'm contemplating the purchase of an LSA type, most of which seem to use the ubiquitous 912 Rotax, but some use the ostensibly more powerful Jabiru 3300. We supplied our first EFI system for a Jabiru 3300 back in 2004 and are now working on parts to fit SDS on the new Gen 4 Jabiru engines. Although the Jabiru's engine sounded in rude health, I felt rusty after 2 months away from an aeroplane, so I proceeded to complete an hour of intense circuit practice (7, T/O's and landings) to get back in the groove. As usual, Dan fails to mention critical issues beyond even complexity and cost of ownership. Kerry is on the web at. On the main Australian forum, the Jabiru bashing has dissipated significantly over the last 12 months. (Jabiru) Bundaberg-based Jabiru Aircraft has dispatched more than 6,500 engines since the company was founded by Rodney Stiff in 1988. I recall some recent horror stories about JAB engines and even groundings by the CAA. I will call him “Bill” as that is what his parents, Mr. and Mrs. Kelso, called him. Ltd. (Australia). Pistons with holes? In time worse things can happen, like fractured piston rings and the havoc that ensues when those large pieces of metal get tossed around inside your case and combustion chambers. Hello, I am Oliver an interested in purchasing a Kitfox 4 with a Jabiru 2200 engine, here in the US. An engine failure should not be blamed on the core engine or design if it has been altered. Flying regularly is a significant factor in an engine’s reliability and longevity. Reliability however is the ability for a machine or component of a mechanical system to operate consistently or repeatedly without failure within the expected durability timeframe. Many of the valvetrain components come from Honda, while the pistons are modified Australian-market GM pieces (the modification is to add a piston pin circlip to keep the pin from riding out and scoring the bore.) Each crank throw is supported on both sides by a main bearing; a traditional aero engine has only a “flying web” between opposed cylinder pairs. He was a regional sales manager for the company that manufactured the bikes and therefore had quick access to service as well as a detailed follow-up on the problem, which was a connecting rod that had not been properly torqued. These bearing shells are, like several parts of the engine, automotive in origin. Because we task engines with keeping us in the air where nature never intended us to be, engines seldom fail at a “good” time. Fixing the tail, installing the engine, and hanging the wings. Aircraft Technical Manuals. In time you’ll get to know what is normal for your engine. A rubber coupling is used for securing the TBI and allows for 360 degree mounting. The Jabiru glistens in beautifully CNC-machined 5000-series aluminum. Seals and gaskets wither. Hi All. Rotax failure rates have always been lower than Jabiru failure rates but it was the twisted data that CASA used in the 2014 Engine restrictions At the height of it CASA lists 40 Jabiru engine failures but this was reduced to 12 after such things as running out of fuel and shutting the engine down after an oil leak etc were removed from the list. Those pistons provide a modest 8.0:1 compression ratio, which would be suitable for auto fuel if only Jabiru were confident of the go-juice’s quality; because it isn’t, the only recommended fuel is 100LL. The 3300 does tend to be worse than the 2200 simply because it has a centre cylinder on each side which requires an even better airflow than the 2200. The engine is very responsive, which is no surprise with a lot of cubes and a single, smallish carburetor, and asking for just a bit of power can result in actually getting a lot. The Sauer seem interesting but what about support and reliability? The piston-powered community, however, has posted engine failures for every engine that has ever been bolted to an airframe. There’s no prop control, no mixture. Jabiru 3300 Rotax 912 (single unit) Rotec R2800 Rotec R3600 Others 90-150 HP. While I don’t doubt that a controllable carb (or fuel injection) would improve the 3300’s fuel specifics, somehow the drop from 7 gph to, say, 6 seems hardly worth the effort. Their attempt to solve a perceived problem causes untold damage, and if the engine does fail it cements in their mind that they were correct all along. The support structure is internal, so no bumps and lumps, nor do you see the typically grotty casting quality evident on your typical Lyconental. A supplied image of a Jabiru Gen 4 engine. Jabiru 2200/3300/5100 Engines. J120, J160/170, J230 Aircraft Technical Manual Issue 10, Jan 2021. That and the Jabiru uses traditional aviation oil, so there’ll be no need to stomp out to the Mobil station down the road from the airport when you need a quart.In many respects, the 3300 is the perfect “tweener” engine, bigger than the stoutest Rotax (for now) and still smaller, lighter, and cheaper than the lowest Lycoming or Continental. In November 2014 the Australian Civil Aviation Safety Authority proposed restricting all Jabiru-powered aircraft to day-visual flight rules only, without passengers or solo students and within gliding distance of a safe place to land due to the engine line's safety record. The cylinder heads were torqued, the valves were adjusted, and the aircraft was again airworthy. In many respects, the Jabiru follows the conventions set by the Rotax 912, arguably the most popular “nonstandard” aviation engine in the last decade and a half. This tapered needle descends into the main jet cavity. Even lying shill Dan Johnson might admit Erwin’s CZAW Sport Cruiser, Mermaid, etc were designed for the superior Jabiru 3300 but supply (and Aussie disgust at Erwin’s business “practices”) forced him to resort to 912. Albeit a used one. Published: March 9, 2006 | Posted In: Sonex News. An owner of a popular 6-cylinder engine, in his quest for even exhaust gas temperatures, replaced the stock intake manifold, mechanical fuel pump, and carburetor with an aftermarket fuel injection system. It can’t be quantified or controlled, it can only be acknowledged as a player in the game. Any engine is prone to failure from human error. Propeller for Jabiru 3300 Engines The WhirlWind GA propeller series are ground pitch adjustable aircraft propellers featuring advanced aerodynamic and composite design. I have been considering a few engine options, but it looks as though the simplest and most cost effective solution is to go with a replacement Jabiru of the latest specification. incl. Nope. In fact, Jabiru lists the 75% cruise consumption of the 3300 as 6.87 gph, which calculates out to a specific fuel consumption of 0.51 pounds per hour per horsepower. This type of break-in procedure is more common on liquid cooled engines that can be broken in on the ground with less risk of overheating. These failures are most likely to occur when an engine is new or has just come out of maintenance. Luck’s role in engine reliability usually plays out when an engine is first put in service or is fresh out of maintenance (as described above) and it typically plays out as bad luck. The induction and exhaust systems are neatly tucked underneath. )Thanks to its greater displacement — the Jabiru six’s 3.3 liters dwarfs the 912’s 1201 cc (74 cubic inches) — the Aussie engine pounds out more power than even the turbocharged Rotax 914, and does so at much lower engine speed. Common sense must prevail, however, and the throttle must be manipulated as necessary if the oil or cylinder head temperatures threaten to spike. A builder I know lost faith in the Brand A engine he had been flying, though he was never able to quantify his lost faith, and swapped the engine out for Brand B. In this airplane, the temps seemed very well controlled, with CHTs staying below the magic 380 degrees — though I don’t know if that number is magic for the Jabiru or not.Cruising is as simple as setting the rpm for the desired power and watching the temps. EFI kits for Jabiru 2200 and 3300 engines. I did some research on the Jabiru 2200 engine, and found VERY mixed reports. Four Stroke, 3300cc (200 cubic inches) 6 Cylinder Horizontally Opposed; Weight: 180 lbs. Oil grows weary of clinging to the wear surfaces it’s supposed to protect and retreats to the oil sump. Its movement is controlled by a large diaphragm above that responds to air density [volume] through the carb. The Jabiru engine has a TO for the “Top End” of 1,000hrs and for complete overhaul at 2,000hrs. It is a direct drive, flat four boxer layout. (Being air cooled, though, a clean inlet flow and appropriately valued exit area remain important. At high volume, like takeoff, the slide rises, allowing more air to flow. They baby them, not trusting the break-in instructions, and the results can be exactly what they are trying to avoid; a damaged engine. Does anyone have any experience with a jabiru 3300 engine? The Jabiru 3300 is a six-cylinder direct-drive air-cooled aircraft engine from Jabiru Aircraft Pty. Does anyone have any experience with a jabiru 3300 engine? Rotax 912ULS or Jabiru 3300. These lifters, removed from a certified engine, show serious signs of corrosion. Matching an engine installation to an airframe is critical to the engine’s success. No two engine installations on homebuilt aircraft are alike, and that is a significant factor in the reliability of any particular engine. “Honey, I have to fly to prevent an expensive engine repair.” When I sold my Sonex, the buyer requested that I continue to fly it until he could arrange for its pick-up. As everyone knows, there are specifications and company propaganda, and then there’s flying. All rights reserved. The 3300 is a modular development of Jabiru's flat-four 2200 engine. When I’m asked this question my answer is honest and straightforward: All of them are reliable, and none of them are reliable. Related products. It’s important to define what an engine failure is so we are all playing on the same field. )In all, the more I look at the Jabiru, the more impressed I become. None of this occurs in an engine that enjoys regular use. Pistons come from the GM/Toyota world, and the hydraulic lifters found in all newer Jabiru engines are right out of a small-block Chevy. A carbureted Lycoming can do better, manually leaned, at around 0.45-0.47 pph/hp; an injected six-cylinder Continental, with balanced injectors, can do an impressive 0.385. Engine Production of the Generation 4 2200 and 3300 engines at the Jabiru Factory at Bundaberg Airport is well underway. The valvetrain is similarly conservative, with a single, underslung camshaft, two valves in each cylinder and simple screw-and-locknut adjustments in the heads. Four Stroke, 3300cc (200 cubic inches) 6 Cylinder … Ltd. (Australia). I don’t have statistics but my observation from current Aussie users of the Jab3300 who post on that forum is that reliability is improving with the mods that Jabiru … Thanks to the 74-mm stroke (2.91 inches), the piston speeds remain moderate. A certified engine on a certified aircraft fell victim to a certified mechanic who failed to tighten a hose clamp on an intake manifold. Ltd. (Australia). Similarly, while the Rotax employs motorcycle-style Bing carburetors, the Jabiru has one feeding an under-engine plenum that shares space, Lycoming-like, with the oil pan. The purpose is to seat the rings in the cylinders. Check out the rest of Marc’s columns. Is the airframe rough? What is the most common cause of engine failure? The NTSB recently announced the probable cause of the Kobe Bryant fatal helicopter crash was the pilot's flawed decision to continue visual... © 2020 Aviation Publishing Group. 10-13-2010, 02:08 PM. To me the best value for power and weight is the 3300… Very few problems reported. The Jabiru, including an exhaust system, all electrics, and the carburetor, is said to weigh 178. piston speed. No, human error. (81 kg.) This wasn’t a kind gesture on his part; he wanted the engine to remain exercised because an engine that sits begins to deteriorate. Kitplanes.com and the Kitplanes logo are protected properties under international copyright law. They don’t grasp that an air-cooled engine relies on air passing through the cylinders, and ground running cannot provide the necessary airflow. 1) Issues regarding the measurement of reliability of the Jabiru engine The design standards do not require an acceptable level of reliability for aircraft or aircraft engines. Your IO-520 is whipping along at 1800 fpm at takeoff and 1533 fpm at a leisurely 2300 rpm cruise setting. Kerry Fores grew up jumping the airport fence in Oshkosh, Wisconsin. These packages often include a cowling (with specific opening recommendations) and cooling fences. To ease cooling concerns, each Jabiru comes with a semi-plenum cooling shroud so that the internal layout of the cowling isn’t quite so critical. I did manage to botch the first landing — trying out my Beech A-36 flare on a knee-height airplane — and noticed the only quirk of the day. All of these engines can fail. All of these engines are capable of providing great service. Applicable to Jabiru 3300cc … Here are pics of two different props I ran on my plane and you can see how the wood prop would push more air into the cooling ducts on the ground than the Warp drive prop would. A cutaway view of the author’s engine installation. In fact, Jabiru lists the 75% cruise consumption of the 3300 as 6.87 gph, which calculates out to a specific fuel consumption of 0.51 pounds per hour per horsepower. It features an aerodynamic enhancement to the design of the vertical tail surfaces for nearly-effortless coordinated handling, the most advanced avionics available for light aircraft, and the latest improvements to the powerful Jabiru 3300 engine. (A basic 912 is some 50 pounds lighter. The company has put that engine on the back burner as it concentrates on the smaller mills. WORLD'S PREMIER INDEPENDENT AVIATION NEWS RESOURCE. To me the best value for power and weight is the 3300. Both of these airframes have the same engine, yet they have different cowl openings. ... My experience with hopped up C series and O-200s is reliability goes out the window. (Yes, I realize that the surface finish of a casting has virtually no impact on its strength, but if I’m paying the equivalent of a decent sports car on an engine alone, I’d at least like it to be attractive.) The motorcycle was limited production and available only by advanced order. Whoa, boy.The final comparison comes with the Continental O-200. There isn’t a single documented engine failure in the soaring community. This feature, along with the solid crankshaft, means a fixed-pitch prop or an electrically adjustable one at best. The likelihood our bikes were neighbors on the assembly line is extremely high. Model: 2200A Serial No: 22A 2723 I have to admit, that I posted the same question in the Jabiru owners Forum, but thought that will also want to ask for Kitfox specific experience. Engine Installation. The party that loaned him the aircraft sent a flatbed trailer to recover it from a few states away. ... My experience with hopped up C series and O-200s is reliability … Fuel, particularly auto fuel, ages, loses its potency, and turns to varnish with a penchant for plugging small orifices in carburetors. We not only sell Jabiru … This is where each builder’s skills and attention to detail comes in to play. However, this design makes sense in light of the Jabiru’s high operating speeds. In fact, Jabiru lists the 75% cruise consumption of the 3300 as 6.87 gph, which calculates out to a specific fuel consumption of 0.51 pounds per hour per horsepower. )Once your gaze has wandered from the machined cylinders, they alight upon the fully CNC-machined cases. This was in response to 46 reports of engine failure in flight. This became the Jabiru 2200. Does any one have any helpful info on reliability … Waiex N116YX, Jabiru 3300, Tail dragger, First flight, 3/16/2013. Then, if necessary, troubleshoot the engine and its installation using the typical diagnostic methods. It was awarded Plans Built Champion at AirVenture 2006. Specification ... Jabiru 3300 Products specifications. Enquire. (Remember that the Rotax has a reduction gearbox.) 403 hours and climbing. After a few weeks of barnstorming he experienced performance issues, which ultimately grounded the aircraft and prematurely ended his summer of barnstorming. Seems a lot more than usual, something you’re at first willing to chalk up to an optical illusion. Airplanes and engines are designed for typical operating conditions and seldom does the designer of a recreational aircraft or general aviation engine consider the needs of someone who revels in flying in extreme heat or cold. The higher the slide, the further the needle comes out of the main jet tube and the more fuel flows. Consider that a 100-hp engine on a 150-mph airframe gets far more cooling air passing through its cylinders than the same engine on an 80-mph airframe. JABIRU 3300 AIRCRAFT ENGINE DOCUMENT No. Failure to keep up with routine maintenance caused the valves to get so far out of adjustment that they weren’t closing enough to provide compression. This page contains photos of a Jabiru 3300A Solid Lifter engine under going a bulk strip and rebuild. behindpropellers. Who knows how it happened—an assembly-person who lost track of what he was doing?—but it happened. Bigger and simpler, too: No liquid cooling setup to deal with, one fewer carb (and no need to synchronize), and a pilot-friendly wet-sump oiling system that obviates the need for an external tank and the traditional “burping” required of the 912 to read the oil level properly. Comes to that, the Jabiru’s diminutive valve covers in some ways remind me of Continental’s technically superior yet ill-fated Tiara series’. But let’s have true perspective: A Yamaha YZF-R6 sportbike, with a teeny-tiny 42.5-mm stroke (1.67 inches), wailing at its (theoretical) 17,500-rpm redline, posts a breathtaking 4880-fpm max. (Rotax says there are more than 15,000 of them in service.) It presents itself as an immediate component failure and is traced to a defective part or workmanship. No cause for the loss of power was determined. AP420CTF-SNR64Z Airmaster Propeller System. A friend and I purchased identical motorcycles from a manufacturer with a reputation for bulletproof engines.
