Nearly a year ago, one of the worst kept secrets in sport aviation finally went public. A new variant of the much used (and abused) Rotax 912 was announced... this one, fuel injected.
According to Rotax sources, the Rotax 912 iS engine will deliver 38% to 70% better fuel efficiency than comparable competitive engines in the light sport, ultra-light aircraft and the general aviation industry.
Mass production of the Rotax 912 iS engines started a few months later and a number are already flying over North America.
Enhancements include a modern fuel injection system and digital engine control unit (ECU) in order ensure optimal fuel and air mixture at any altitude for longer flight range, lower operating costs and CO2 emission reduction. The new Rotax 912 iS engine also provides a time of 2,000 hours between overhauls (TBO); the same TBO as the 912 engine.
With more than 170,000 Rotax aircraft engines sold in almost 40 years, Rotax Aircraft Engines dominate the light sport and ultra-light aircraft market. With 20 authorized distributors and a network of more than 200 sales and repair centers supporting customers worldwide, BRP supplies engines to more than 80% of all aircraft manufacturers in its segment.
