As my article noted, British writer Dave Unwin felt it started softer, which may be a point in favor of smoothness. The 2008 is a bit longer and larger than the Astore and thus handles turbulence and cross wind landings a bit better. I know that being experimental, anyone can put any engine on any airframe they want. It is true that the 115 hp is available for five mins. any and all info you can provide would be golden. I wonder if this is the same defensive mechanism among maintenance personnel that used to be common back in the 70s and 80s when fuel injected cars were becoming the norm or do they know something about 912is we dont..? Engine performance may vary depending on, among other things, general conditions, ambient temperature and altitude. Even as the 912 iS was being announced last year, Rotax was already flying comparison trials, but the initial fuel economy data it released was based on dyno runs and some flight testing. The Rotax 912 was first sold in 1989 in non-certificated form for use in ultralights and motorgliders. The 912iS requires a more robust installation, as mentioned, things like metal fuel lines which require exact fits, unlike rubber hose, butit also requires the sensor tiedownkit, which is a few hundred dollar kit,with sensor specific tie downs to eliminate false alarms due to sensor vibration. - All Rights Reserved. This is beyond my experience base so will leave that debate to the forum.

This was done at multiple altitudes. Takeoff roll is substantially reduced. Ive been flying a P2008 with the 912iS for over 3 1/2 years out of CA, in the mountains. To expand the data envelope, multiple aircraft were refitted with the 912 iS. Production started in March 2012 and the engine has a 2000-hour recommended time-between-overhaul to start. 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. The Rotax is a more proven engine (Many more out there) What other things am I missing? 912iS. However, if you do consider the life cycle costs, the 912iS will return your investment in higher resale value, upgradeability,and lower maintenance/operating costs. Overall I would argue better minds than ours made a good call.

The 80hp (60kW) versions are sufficient to power the new generation of efficient motorgliders, such as the Pipistrel Sinus and the Urban Air Lambada. Your need to keep the greasy side down may be 'cause you pushed the pistons into the sump with over boost at low engine speed. Although I loved the power of the 915iS with its shortened takeoff roll, thrilling climb to altitude, low-speed fuel economy, and quiet running, the 912iS ismore my kind of engine. Lubrication is dry sump, and fuelling is via dual CV carburetors or fully redundant electronic fuel injection. Im about to take the plunge! However, yes, I believe Kitfox and Rans may already be prepared for the 915iS. There has been much made of early issues with the 912iS.

This is a surprisingly common accident factor in floatplanes in particular for whatever reason. 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. [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. Without providing much detail, Rotax said the 912 iS is also capable Lambda 1.3 or lean-of-peak operation. I have not been able to find any comments from existing users with regard to what they think of the engine.

Regardless all the electrical power to run the engine comes from the engine. The injected engines have/require among other things metal fuel lines, high pressure filters, and providesubstantially more electrical power along with over 27 engine sensors and dual redundant Engine Control Units (ECU). 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. 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.

[5] In addition to the lower fuel consumption, the 912 is certified to run on automotive fuel (mogas), further reducing running costs, especially in areas where leaded avgas is not readily available. The hardest part is having to get so close to a spinning prop. That's a $12,700 price premium or about 9 percent. As you can see in the contrasting Stock Box images, we saw as low as 2.8 gallons per hour resulting, of course, in lower speed flight. No other modifications were done, according to Mitter, other than fuel plumbing. This decision can be reversed. For everyone else simplicity is probably best. Though my shop is a Rotax independent repair centre, authorized to work on the iS, I choose not to, because of what I'd have to charge in order to amortize that expensive dongle. Marc Becker summarized, The 915iS is about 12 kilos (26 pounds) more for the engine only; 40-50 more pounds when installed and about 3,000 ($3,750 at todays exchange rates) more than the 914. It is significantly more than the 912iS, as you should expect for an engine with substantially more power and the ability to use that power up to higher altitudes. A highlight for private pilots and enthusiasts, this limited-edition design of our popular Rotax 912 iS Sport aircraft engine comes with a unique service and warranty package. Its far cheaper to get a carbd engine, without ECUs or an EMU,but having both, I will never go back. So perhaps the right answer is to add 2 more planes to my stable? When zipping along faster than 170 miles an hour true, consumption rose to the 7-9 gph range. The 912is is the latest in technology, full fadec w automatic lean of peak operation below 97% power. We already do it for Light Sport and to Light Sport Sea. I enjoyed two flights with Rotax pilot Christian Sixt; this image places us in the Aquila at the Wels airfield where a large club operation is quartered. Over the eventual 2000-hour TBO of the 912 iS, the engine will use a whopping 2800 gallons less than the ULS, for a savings of $16,800. What the refreshed experience told me is that FAA was right to say this is unnecessarily complex for recreational pilots. Many of the early installs didnt have this, mine didnt so we immediately added it and this is likely why we have had zero faults. The iS is a nice improvement over the ULS but is high tech for sure. Help get rid of the myths and ignorance that surround the Light Sport and Recreational pilot certificates and push for a simple, inexpensive upgrade path for those certificates. The 914 is a mature design but the turbo can be additional maintenance if a few basic care rules are not followed. You have declined cookies. 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. 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. Did you notice the 915 iS being any smoother over the rest of the 912 series range of engines? 80mm, P.C.D. The 912 iS ECU is programmed to run in eco mode at 77 percent power or less, at which point the engine will operate at what European engineers know as Lambda 1, or a stoichiometric air-to-fuel ratio of 14 to 1. Soon after advancing the throttle, I noticed greater acceleration but two other parameters were more obvious. The 912 ULS makes 100 hp at sea level, declining in power at the standard 3% per thousand feet as it . kicktireslightfires, Jun 16, 2020 #1 Ghery Touchdown! Paste as plain text instead, My best friend has one in his Europa. . The 912 iS is approved for 91 AKI mogas, but in equipping the engine with future knock-sensing capability, Rotax seems to be anticipating approvals for lower-octane fuels. 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. [1] Originally available only for light sport aircraft, ultralight aircraft, autogyros and drones, the 912-series engine was approved for certified aircraft in 1995.[2].
