Abstract:
This paper reports on the preliminary investigation of the identification of a method to model the transient operation of a single cylinder four-stroke gasoline engine.During a transient the response of an engine and the actual fuel mixture delivered to the engine are significantly affected by the behaviour of the fuel injected into the inlet manifold. In the past, different wall-wetting theories have been developed to model and attempt to resolve this problem and one of the most definitive is investigated here along with two other theories developed at QUB.A steady state computer model of a single cylinder four-stroke spark-ignition research engine was written and validated. The three different wall-wetting theories were studied and each individually integrated into the steady state model. This allowed simulated transients to be performed on the computer and the results generated to be compared with firing transient tests.
