BRP's Rotax aircraft engines offer outstanding performance, continued reliability and best power to weight ratio in its class.
What makes Rotax 4-stroke aircraft engines unique?
Rotax aircraft engines have a reduction gearbox equipped with a damping device to minimize torsional vibration. Based on the optimized rpm setting of the propeller it provides outstanding efficiency, reduced emissions and noise.
Rotax aircraft engines are equipped with a dual ignition unit of a breakerless, capacitor discharge design, with an integrated generator. The ignition unit needs no external power supply.
Built crankshafts allows BRP to design compact, low weight engines.
Rotax aircraft engines are provided with a dry sump forced lubrication system with a main oil pump with integrated pressure regulator and oil pressure sensor. The oil pump sucks the motor oil from the oil tank via the oil cooler and forces it through the oil filter to the points of lubrication in the engine. The surplus oil emerging from the points of lubrication accumulates on the bottom of crankcase and is forced back to the oil tank by the piston blow-by gases.
The cooling system of the Rotax 4-stroke aircraft engines is designed for liquid cooling of the cylinder heads and ram-air cooling of the cylinders. The cooling system of the cylinder heads is a closed circuit with an expansion tank.
