Research into three-component biodiesel fuels combustion process using a single droplet technique

Abstract

In order to reduce the engine emission while at same time improving engine efficiency, it is very important to clarify the combuction mechanism. Even if, there are many researches into investigating the mechanism on engine combustion, so that to clarify the relationship between complicated phenomena, it is very dificult to investigate due tothe complicated process of both physical and chemical reaction from the start of fuel injection to the and of combustion event. The numerical simulations are based on a detailed vaparization model and detailed chemical kinetic. The influence of different physical parameters like droplet temperature, gas phase temperature, ambient gas pressure and droplet burning velocity on the ignition delay process is investigated using fuel droplet combustion stand. Experimental results about their influence on ignition delay time were presented.
