Abstract

In this paper, first, based on the principle of sensitivity analysis, the key combustion control parameters that influence the combustion characteristics index indicated mean effective pressure (IMEP)and crank angle of 50% heat release (CA50) of diesel low temperature combustion(LTC)are determined by experimental study, which lays a foundation for simplifying the combustion control of diesel LTC. Then, the regulation law of the key combustion control parameters and the influence of that on the combustion characteristics IMEP and CA50 are further analyzed by using the experimental data. Finally, based on the above analysis, the physically-based control-oriented IMEP and CA50 model are developed. The model is validated by using the transient diesel experimental data and the validation result shows that the model can predict not only the dynamic characteristics but also the IMEP and CA50 of diesel engine under LTC conditions, accurately.
