Study on the Prediction of Performance and Emission in a 4 - cylinder 4 - stroke Cycle Turbocharged Gasoline Engine 912471

A computer simulation program has been developed for predicting the performance and emission of a multi-cylinder turbocharged gasoline engine.
The two-zone expansion model and the method of characteristics were adopted to evaluate the properties of the gas in the cylinder and pipe respectively. The flow through the turbine and compressor was calculated by using the characteristic charts. To predict exhaust emission, twelve species were considered to be present in combustion products, and the concentrations of these species were calculated through equilibrium thermodynamics and kinetic theory.
The simulation models were selected not to depend much on the empirical constants. For the indispensable empirical constants, the easy ways of their determination were suggested.
