ROTAX, a name that is synonymous with light aircraft, LSA aircraft and even
military drones and in a co-operation with Pipistrel today marks a very
important milestone in the history for ROTAX with the release of the new
fuel injected 912 IS aircraft engine.
This new engine the ROTAX 912 IS produces 100 hp from what is basically
the same engine core as the 912 ULS with the exception that the
carburettors are gone, now replaced with modern fuel injection. This
relieves the engine from carburettor imbalance and provides perfect
start-up/shutdown and idle just like a modern car. The choke has gone and
the engine responsiveness has been increased substantially along with an
approximate 10% reduction in fuel consumption at normal cruising speeds.
As the world's leading supplier of aircraft engines for Ultralight and LSA
aircraft, ROTAX aircraft engines have truly revolutionized the aircraft
industry. The popularity of these engines continues to soar higher and
higher, from the original two-stroke engines through to the modern four
stroke engines ROTAX produce an engine for just about every aviation
application and many hundreds of non-aviation applications.
The 4-stroke 4-cylinder boxer engines we are now familiar with and known
as the ROTAX 912 series started development in 1984 having advanced
technology and superior weight/performance ratio and have propelled
experimental, Ultralight, LSA aircraft and motorgliders for many years
gaining themselves an enviable reputation for reliability, low noise, fuel
efficiency and most important actually reaching the TBO times. ROTAX
aircraft engines are available in two configurations including fully
certified engines as well as noncertified engines; both are very similar
and enjoy a fantastic reputation.
Today is a significant milestone for both Pipistrel and ROTAX with the
release of the 912 IS engine, ROTAX have chosen Pipistrel as the 912 IS
release customer and the engine has been fitted and tested on the
award-winning Pipistrel Virus SW aircraft. Those that have flown the
aircraft report increased smoothness, faster throttle response, lower idle
and most importantly for the environment less fuel consumption for this
exciting new engine. Now a little history lesson.1920 The company was
founded in Dresden, Germany as ROTAX-WERK AG.1930 Taken over by Fichtel
& Sachs AG, the company transfers its operations to
Schweinfurt/Germany.1943 The company=99s operations are relocated

Ski-Doo snowmobile developed by bombardier.1970 This year sees
integration of Bombardier and ROTAX. The former Bombardier Inc. branch BRP,
now an independent company, uses ROTAX engines in its motorcycles, personal
water craft, and snowmobiles.1977 High orders of snowmobile spare
engines ROTAX=C2=AE 185, 248, 284, 294 are also used in Ultralight
aircraft.1978 Ultralight engines 501, 505 developed (based on snowmobile
engine 503).1982 The company begins development of ROTAX 4-stroke
aircraft engines, a landmark in ROTAX history.1983 The company starts
producing ROTAX motorcycle engines for APRILIA.1984 Start of sales of
ROTAX 912 engines.1988 The company starts producing ROTAX marine engines
for Bombardier Sea-Doo watercraft.1989 Type certificate for ROTAX
912A1993 The company starts producing ROTAX motorcycle engines for BMW,
Germany.1994 Type certificate for ROTAX 912F.1996 Type certificate
for ROTAX 914F.1998 Type certificate for ROTAX 912S.1998 The company
starts producing ROTAX engines for Bombardier ATVs.2000 The company
begins initiation of The ROTAX Quality Production System (RQPS).2001
Launching of ROTAX 4-TEC 4-stroke engines for Sea-Doo watercraft.2002
This year witnesses the launch of the new 2-stroke semi-direct electronic
injection technology: ROTAX 2-TEC engines for Ski-Doo snowmobiles, plus the
launch of the ROTAX Kart RM1 with direct drive (without chain).2003 Sale
of Recreational Products Group by Bombardier Inc.; Foundation of Bombardier
Recreational Products Inc. (BRP) with BRP-ROTAX as part of the new
company.2003 Approving BRP-ROTAX as International Design Organization
according to JAR-21, the European Joint Aviation Authorities (JAA).2005
85th anniversary of ROTAX is celebrated and 35 years with BRP.2005 912 /
914 Series compliant to Light Sport Aircraft ASTM Standards.2006
Production of the 6 millionth ROTAX engine.2006 582 engine compliant to
Light Sport Aircraft ASTM standards.2008 ROTAX stars manufacturing the
1125 cc Helicon liquid-cooled, four-stroke, fuel-injected 72=CB=9A V-Twin f
or
the Buell Motorcycle Company.2009 912 Series TBO (Time Between
Overhauls) increased from 1500 hours to 2000 hours2010 914 Series TBO
increased from 1200 hours to 2000 hours2012 Release of the new ROTAX 912
IS engine More than 150,000 ROTAX Aircraft Engines have been sold since
1973. Today, ROTAX manufacture the 582 engine series (2-stroke) and the 912
/ 914 engine family (4-stroke). All these engines are approved for use with
Ethanol 10 fuel, MOGAS and AVGAS. Considering the approved usage of MOGAS
and the low fuel consumption the fuel costs of a ROTAX 912 series engine
are up to 50 % lower than for a comparable 100 hp air-cooled piston engine.
With low operating costs, leading class power to weight ratio, well known
reliability, it is no surprise that ROTAX Aircraft Engines are the first
choice of more than 200 aircraft manufacturers worldwide and today
Pipistrel is proud to be involved as the release aircraft manufacturer for
this new exciting milestone for sport aviation.
