Other than official Rotax pilots and select airframe builders, we were among the first to experience the powerful new engine from the worlds leading producer of engines for light aircraft. I can inquire, but so can you, directly with the engine manufacture. But more air is added in the combustion chamber He also explained that (perhaps surprisingly to some readers) the 915iS compression ratio is lower to allow for the turbo boost. [4] The 912 may be operated using leaded fuel, but this is not recommended as lead sludge tends to accumulate in the oil tank and reduction gearbox. Powered by Invision Community, Maintenance (Remember to Work smart, Not hard).

That would be sweet! This decision can be reversed. The 912's popularity was greatly enhanced by the introduction of the light-sport aircraft category in Europe and the United States, which resulted in the introduction of many factory-built aircraft designed to fully exploit the engine's small size and light weight. Just SuperSTOL coming along ok working out 915 problems. For both engines, the aircraft was climbed to a specific altitude, leveled and allowed to stabilize on one fuel tank. ROTALK NEWS Episode4ROTAX's 915iS-powered Aquila A211 test aircraft, the Scheibe SF-25C Falke (first-ever 912-equipped aircraft!) A fellow aviation journalist a pilot of 300 different aircraft Dave Unwin felt the 915 started softer. He also felt it seemed to run slightly smoother.

Thank you so much. The compression ratio is one thing the pressure inside the combustion chamber is another thing, in a turbo engine the the air is forced inside the combustion chamber in a normal engine is aspirated, thats why even at lower compression ratio the pressure inside a turbo engine is much higher. Pasted as rich text. Rotax engine experts felt most of this is attributable to software and the same code can also be applied to the 912iS. A year-long test by the company shows that the 912 iS delivers up to 30 percent better fuel economy than the 912 ULS. Now a few years after the 912iS was released, it has become a well refined engine, IF it is installed according to Rotaxs manual and instructions. The short TBO and lack of certification for use in factory-built type certificated aircraft initially restricted its worldwide market potential. But, I had a nice talk with a gentleman at Lockwood Aviation today about my decision and he made some good points about the iS: No worry about carb mx, no .

In a weight-to-power comparison grams per kilowatt hour fuel consumption is only about 6% higher in the more powerful engine. Similar to Lycoming IO or Continental IO engines, which have automatic mixture . Entering the Market Marc indicated that 200 915iS engines have been delivered into the Rotax network including distributors around the globe. 100mm, Shaft with flange for fixed pitch propeller, P.C.D. Impressive but no more horsepower than the ULS and likely less in many conditions. Carbs are never "better" in terms of performance the only potential benefit of using carbs would be that , in some scenarios, they are simpler to troubleshoot and fix and don't need electricity to run. What make and model of turbocharger does Rotax use on the 914 and 915is engines? By using our website, you agree that we can place these types of cookies on your device.

The 912is has a few minor Differences/Improvements but the rest of the engine is essentially the same. I would buy another 912iS if I were to build another A/C. You do not have permissions to reply to this topic. In a four-cylinder, high-RPM geared engine, that sounded like an overpromise. For that question Im a firm advocate of the injected engine. The 912iS has 2 stators one dedicated to engine operation and one to provide electrical power for the airplane. Its numbers rival diesel performance. A $20,000 more than the ULS and $8,000 more than the 912is!

When single lever constant speed (CS)props become available, hopefully late this year, only the iS engines will be eligible sincetheyarefull fadec engines,that means only the 912iSor 915iS. Electronic fuel injection requires electrons. The engine differs from previous generation aircraft engines (such as the Lycoming O-235) in that it has air-cooled cylinders with liquid-cooled heads[4] and uses a 2.43:1 PSRU reduction gearbox to reduce the engine's relatively high 5,800rpm shaft speed to a more conventional 2,400rpm for the propeller. But more likely, it will account for just a substantial fraction of the overhaul cost. Clear editor.

Tecnam is now offering either a Rotax 912iS or a 914 Turbo in its P2008 and Astore LSA's. * On the point about an in-flight adjustable or constant speed prop, Rotax Aircraft Engines top boss Thomas Uhr made an important statement when I asked about fixed pitch props on the 915, All our engines can use fixed pitch props. As a leader of a public company, he spoke carefully, but the suggestion was clear: Yes, a fixed pitch 915iS is coming, although today the engine is only driving an in-flight adjustable prop.

This requires a novel preflight inspection procedure: before checking the oil level with the dipstick, the engine is "burped" by removing the oil filler cap and turning the propeller until a gurgling sound is heard, which indicates that all oil has been forced into the tank and the oil level can now be checked accurately. And, there were a lot of SBs on the 912 iS early on.

Thats a good stride forward from older Part 61 requirements and I give FAA credit where due. Similarly, in cruise, the iS did better at low altitudes than Rotax originally calculated, but at higher altitudes8000 feet and aboveit did much better, showing as much as a 36 percent improvement over the ULS fuel burns. 2 cents worth from an owner, Id say buy the 912iS or wait until the 915 is available, avoid the old tech dual carbd engines regardless of cost. Their state of development appears good now but prices need to come down and regulations need to be completed as presently forecast. The manual adds that non-compliance with such warnings could lead to serious injury or death.[10]. Dan, So I'm about to buy a pipistrel virus SW and was wondering if the 912iS is a better option over the 912ULS in the general community's opinion.

I found the engine to fly flawlessly in my experience and powerfully! Im pleased you appreciate the effort. When I can Ill look myself, perhaps I will add to this comment. The discussion forum for Sport Pilots and Light Sport Aircraft, Post For decades I owned and flew numerous CS set ups with aseparate prop control and think I would prefer that. [Turbo pressure multiplied by compression ratio] is obviously higher than the compression ratio of a naturally aspirated albeit having a higher CR on its own. One difference from prior experience was the Stock Box instrument (more formally, Stock Flight Systems Engine Monitoring Unit or EMU) developed by Michael Stock incollaboration with Rotax.
