Through experiments conducted on a single cylinder direct injection (DI) diesel engine,
effects of exhaust gas recirculatoin (EGR) on combustion and emission during cold start …

Diesel engine cold start is an important issue for current technology at low (below 0° C)
temperatures and for future applications. The aim of this work is to develop a description of …

Diesel engine combustion instability during cold starting period is characterized by unstable
engine speed and large amount of white smoke emissions caused by misfiring cycles …

The physical in-cylinder processes and ignition during cold starting have been studied using
computational models, with particular attention to the influences of blowby, heat transfer …

Low compression end temperatures, high heat loss, and large resistance torque cause
difficulty in starting conventional diesel engines at extremely low temperatures. The diesel …

Various single and split injection schemes are studied to provide a better understanding of
fuel distribution during cold starting in Dl diesel engines. Improved spray-wall interaction …
