Engine And Vehicle Power, Fuel Economy Matches The Simulation Calculation

This thesis deals with the quasi-dimensional combustion model of the gasoline engine to calculating unsteady operating modes, which can calculate the variations of the engine抯 property index in pace with the changes of the work status. It also presents with a simulation calculating program of automobile dynamical characteristic and fuel economic characteristic. It describes the matching between the engine and automobile dynamical characteristic and fuel economic characteristic by calculating the characteristic parameters of the light cross-country automobile BJ2O2OSQ and compares various property indexes under the condition of BN492Q and BN492D1QB. It analysis the effects to dynamical and fuel economical characteristic which are caused by the variation of parameters of automobile transfer system. An approach is given to improve transportation efficiency and cut down the fuel consume by select a reasonable match of automobile dynamical transfer system.
