Summary:

The multicylinder turbocharged engine was simulated by assuming each cylinder undergoes the same thermodynamic cycle. The model for the cylinder includes instantaneous heat transfer, homogeneous combustion burning rates, and a scavenging model which allows any intermediate mode between perfect scavenging and complete mixing. Metal surface temperatures are calculated by use of cyclic energy balances. The air receiver pressure is assumed constant and the exhaust manifold pressure is calculated by use of a filling and emptying process. The turbocharger turbine is analyzed on a quasi-steady basis with given mass flow-expansion ratio characteristics and efficiency-velocity ratio curves. Steady flow is assumed and experimental performance was used to model the compressor. Engine and turbocharger operating conditions are adjusted in the program until an energy balance is attained between the engine and the turbocharger.Comparisons between experimental and simulated data are presented and the results of parametric variations are discussed
