Analysis of combustion behavior in DI diesel engine at low temperature; DI diesel engine ni okeru teionji no nensho kyodo kaiseki

Abstract

For NOx reduction of a DI diesel engine, the retard of fuel injection timing is effective. However, it causes the white smoke at low temperature and low load. To analyze the mechanism of white smoke generation, a new visualizing system of fuel spray and flame behavior has been developed. This system can be also applied to a 4-valves per cylinder production engine by integrating two optical systems for image and lighting. From the visualization of the fuel spray and the flame behavior in the combustion chamber at low temperature, it has been proved that prompt fuel evaporation before reaching the wall surface of combustion chamber is required to reduce the white smoke. 6 refs., 10 figs., 3 tabs.
