Abstract


Wankel engines are increasingly finding their application in unmanned aerial vehicles, especially where high power-to-weight ratio is of utmost importance. This advantage makes the Wankel engines outperform the reciprocating engines despite several shortfalls. 1-D simulation model of the Wankel engine has been constructed from commercially available software for reciprocating piston engines. This model was then used to study the matching of turbocharger for the required application and the effect of charging the engine. The developmental methodology of a turbocharged wankel engine based on 1-D simulation approach is described. The behavior of the engine and turbocharger at various altitude conditions were studied with a validated model. The simulation model was then used to study the intake and exhaust manifolds and also to design the wastegate opening strategy & ECU correction factors for various altitude conditions. The model has been validated with the test results from prototype engine with the selected turbocharger at sea level operating conditions.
