INVESTIGATION INTO SOME ASPECTS OF THE COMPUTATION OF DIESEL ENGINE COMBUSTION.

The authors have proceeded by constructing three basic combustion models each based on the same general idea that the fuel jet behaves in a similar way to a jet of pure gas. The models differ in complexity and hence computational cost, mainly because of the assumptions made concerning the variation of properties within the jet. Computed and observed cylinder pressure diagrams have been compared for a single cylinder, quiescent chamber engine over a wide range of mean effective pressures and injection configurations.
