Tóm tắt

In an internal combustion engine, whenever complete combustion can be achieved, indicated torque production is directly related to fuel rate. This premise is exploited to extrapolate a public-domain, homogeneous charge, spark ignition engine model to the stratified charge regime. The extrapolation is based on published, functional forms for indicated torque and friction torque in a direct-injection, spark ignition engine. The extrapolated, control-oriented model is "validated" through comparisons to both published results and expected behaviors. The dynamic model is illustrated through step responses in fuel and throttle flow rate.
