A Model for Fuel-Air Mixing in the Texaco Controlled Combustion Stratified Charge Engine,

摘要

A jet model with standard turbulent entrainment assumptions has been developed to predict the spray formation processes in engines. The model has specifically been applied to controlled combustion system,stratified charge engine. While the analysis has been carried out as part of a general effort to develop a model to predict the performance of the engine,the potential use of the jet model,by itself,as a design tool has also been demonstrated through a parametric study. Some characteristic lengths useful in evaluating different fuels have also been described. The purpose has been to show that the performance model developed for the engine can be used for a large number of fuels of practical interest.
