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. JABIRU 3300 AIRCRAFT ENGINE DOCUMENT No. This is where each builder’s skills and attention to detail comes in to play. This is common on air-cooled engines with solid lifters. Non-certified engines range from the popular auto engine conversions, like those based on the original VW Type I engine, the Corvair engine, and even the Model A engine (made popular and still used by the Pietenpol community), to engines designed specifically for aircraft use like ULPower, Jabiru, D-Motor, and more. A constant thread throughout my articles is the human factor in homebuilding. Therefore, we must fly in a manner that lessens the consequences of an engine failure. I did some research on the Jabiru 2200 engine, and found VERY mixed reports. Given a choice, who wouldn’t put the most reliable engine on their aircraft? To me the best value for power and weight is the 3300… He wanted to build an airplane in 10th-grade woodshop but was asked to choose a smaller project. 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. As usual, Dan fails to mention critical issues beyond even complexity and cost of ownership. Jabiru’s literature calls out eight bearings on the six-cylinder engine, apparently counting the split shells on the crank nose as two. 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. The high temperatures they witness after a 20 minute ground run at partial throttle convinces them those temperatures will soar under flight conditions, when full throttle is applied. Gaps in the cooling baffles and incorrect (or purposely modified) cowl outlets and inlets play a large role in an engine’s ability to keep cool. It was awarded Plans Built Champion at AirVenture 2006. Description The J230-D is the flagship LSA model in a long lineage of Jabiru aircraft. Back to the crank design. Applicable to Jabiru 3300cc … AP420CTF-SNR62H. While two-control airplanes were designed to make a pilot’s life simpler, they come with significant compromises. Inside the carburetor throat is a piston [called a slide] that descends to block air flow. The J2200 is an 80HP aircraft engine manufactured by Jabiru in Australia. This feature, along with the solid crankshaft, means a fixed-pitch prop or an electrically adjustable one at best. All rights reserved. The valvetrain is similarly conservative, with a single, underslung camshaft, two valves in each cylinder and simple screw-and-locknut adjustments in the heads. It’s important to define what an engine failure is so we are all playing on the same field. 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. Hi All. 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. 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. The cylinder heads were torqued, the valves were adjusted, and the aircraft was again airworthy. Thanks to the 74-mm stroke (2.91 inches), the piston speeds remain moderate. 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. Enquire. So a four-cylinder Lycoming, for example, has but three main bearings, albeit very large ones, particularly the massive bearing between the prop flange and the first set of cylinders. AP420CTF-SNR64Z Airmaster Propeller System. When you cross paths with someone complaining about the engine problems they’ve had, trace your eyes down the airframe it’s mated to. Some of these conditions can be seen as inconveniences; a weak battery can be charged, corroded terminals can be sanded. by Pete Twissell » Tue Oct 10, 2017 12:48 pm "cruise today was 100 kts at 27,500 rpm" All engines, regardless of manufacturer, are mechanical devices and mechanical devices can fail. 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. (Jabiru) Bundaberg-based Jabiru Aircraft has dispatched more than 6,500 engines since the company was founded by Rodney Stiff in 1988. Propeller Manuals. 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. Musk and the FAA should declare a truce and get back to the remarkable work at hand. (More on that further down.) Airmaster makes a specific model for this engine. 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 … 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. (Remember that the Rotax has a reduction gearbox.) Jabiru recommends checking the valve lash several times early in the engine’s life, but the job appears to be a simple one. To me the best value for power and weight is the 3300. To that end, some aircraft designers and engine manufacturers have developed installation packages specific to common airframe/engine combinations. The purpose is to seat the rings in the cylinders. If you can’t think of what they may be, I have a story that will help. Take it one step further — as Continental and Lycoming (and Franklin and Pratt & Whitney and Wright) did — and bolt six cylinders to the case and you have the 3300, capable of 120 hp maximum and 107 continuous. Please note that links on older archive pages are often not active. Manuals and User Guides for Jabiru 3300. 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. 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. You have entered an incorrect email address! But the exaggerated offset is real, the result of a five-main-bearing design for the four-cylinder and a seven-main design for the six. Here’s an example. My friend’s bike developed a knock within minutes of starting the engine. Who knows how it happened—an assembly-person who lost track of what he was doing?—but it happened. It’s a simple and largely effective system. In 1998, unconstrained by teachers, Kerry scratch built a Sonex he polished and named Metal Illness. The induction and exhaust systems are neatly tucked underneath. We not only sell Jabiru … Not exactly grumbly but not bumblebee, either.From inside, the 3300 moves the Jabiru smartly down the runway and results in very good climb considering the power loading. This was in response to 46 reports of engine failure in flight. From my experience most engine failures are installation, operation, and maintenance errors. The Sauer seem interesting but what about support and reliability? 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. That 3.3-liter displacement is 201 cubic inches, making this a great comparison with the Continental O-200. 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. Re: Jabiru 3300 I agree that the different props affect the cooling on the ground more than in the air. The Jabiru 3300 is a lightweight four-stroke, horizontally opposed "flat-six" air-cooled aircraft engine produced by Jabiru Aircraft.The engines are direct drive and fitted with alternators, silencers, vacuum … Four Stroke, 3300cc (200 cubic inches) 6 Cylinder Horizontally Opposed; Weight: 180 lbs. Learn how your comment data is processed. “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. An air-cooled engine cannot be properly cooled during extensive ground operations with its cowling on or off.
