Introduction This paper presents a model of a four-cylinder spark ignition engine, which shows the capability of Simulink to model an S.I. engine from the crankshaft output down to the throttle. Back ground The basic model accommodates the capabilities of Simulink 2 to ascertain the time- based events with high accuracy. In the simulation, the subsystem models transfer fuel and air mixture from the intake manifold to the cylinders via the valves. This occurs concurrently with the time processes of the intake flow, torque generation and acceleration. A second model subsystem is triggered which provides the closed-loop engine speed control via the throttle actuator. These models can be applied as stand-alone engine systems. Model description The model is based on the published results by Crossley and Cook (1991), which describes a simulation of a four-cylinder spark ignition internal combustion engine. The Crossley and Cook work shows how the simulation model was validated against a...
