Abstract
A dynamic model of a gaseous-fuel engine is developed in order to design an engine control system. This model includes estimation methods of dynamic characteristics to be affected by components in mixture. An effective air mass ratio is defined as air mass flow divided by mixture mass flow, and is proposed to predict variations of the air flow, manifold pressure and the air-fuel ratio according to the water vapour and the gaseous fuel in the mixture. The dynamic engine model is validated with a liquefied petroleum gas (LPG) engine-dynamometer under steady and transient operating conditions. Experimental results from an LPG gaseous-fuel engine show that estimation of the airflow and the air-fuel ratio based upon the effective air mass ratio is more accurate than that of a normal engine model.
