In-Cylinder Flow and Combustion Modeling of 1.7L Caterpillar Engines 900253
This paper details the development of a mathematical model to simulate the incylinder processes in the Caterpillar 1.7L Diesel engine and the results obtained during compression stroke and early part of the combustion stroke. The model includes accurate representation of the geometry of the 1.7L combustion chamber via Body Fitted Coordinates (BFC) which conform to the shape of the piston-dish and cylinder. Also included are the combustion model and evaporation model. This 3-D model predicts average cylinder pressure and temperature variations with degree crank angle which are in good agreement with Caterpillar measurements for this engine.
