Prediction of Gas Exchange Processes in a Single Cylinder Internal Combustion Engine 790359

The study of unsteady gas exchange processes in the intake and exhaust systems of an internal combustion engine is presented in this paper. A finite difference scheme is used for solving the equations defining these systems. The transient properties like the pressure, temperature and velocity in these systems are computed by the present scheme and are compared with the results obtained using the pressure measuring devices and an ultrasonic instrument which can simultaneously measure the gas temperature and velocity.
