Increased understanding of fuel-air mixing can lead to cleaner diesel engines

Chengjun Du’s research is about heavy truck engines. The results of his PhD thesis "Studies on diesel sprays under non-reacting and reacting conditions” can lead to cleaner diesel engines, which will reduce greenhouse gases and air pollution.
Methods for reducing engine-out emissions are urgently needed. In diesel engines, the quality of fuel-air mixing and the subsequent combustion process strongly affect fuel efficiency and engine-out emissions. However, fuel-air mixing, the subsequent combustion processes, and their dependence on the operating conditions are not yet fully understood. 

Chengjun Du’s PhD thesis "Studies on Diesel Sprays under Non-Reaction and Reaction Conditions" aims to address this deficiency. His PhD project is related to heavy-duty truck engines, and his project is to mainly investigate diesel fuel combustion under various operating conditions.

“My thesis improves the understanding of diesel fuel combustion processes, which will result in reducing diesel engine soot emissions and further decreasing CO2 emissions. The results will help to guide engineers to design the engine” says Chengjun Du
