Four-stroke cycle for low emissions and fuel consumption
Excellent starting over a wide temperature range -20°C to +40°C
Ideal compact combustion system with no hot-spots
Turn-key heavy fuel operation
Insensitive to changes in AFR or ignition timing
Insensitive to changes in fuel composition or altitude
Resistant to detonation and carbon build up
Large valve breathing area gives high power with a wide power band
High reliability, low maintenance with long MTBO
No injectors in the combustion chamber to carbon up
No valve clearances to adjust
Shielded spark plug for minimum plug fouling and long life
Designed as a UAV engine not modified from a hobby engine
Electronic fuel injection system with altitude compensation
Dedicated mounting system for 100 W to 3 kW alternators
