The paper presents a computer simulation of flow and heat transfer phenomena in the intake port of a spark ignition engine with port fuel injection. Engine cold starting conditions are studied including the effects of in-cylinder mixture back flow into the port. One dimensional air flow and wall fuel film flow models and a two dimensional fuel droplet flow model have been developed using a combination of finite difference approaches. As a result, predictions are obtained that provide detailed picture of the air-fuel mixture properties along the intake port.The model may be of special importance for exhaust gas ignition system simulation as it will provide data concerning mixture formation under conditions of excessive fuel injection during engine start-up.The calculations performed are shown to be phenomenologically correct.
