In a direct injection (D.I) diesel engine with high efficiency, the blue and white smoke (cold smoke) exhaust at cold starting and warming-up are unsolved problems in the development of small D.I diesel engines. In this experiment, the fuel adhering on the combustion chamber wall, and which influences the cold smoke, was measured on a special engine which can be stopped immediately after a single injection.It is found that 30-40% of the injected fuel remained on the combustion chamber wall after burning at low compression ratios and under low temperature conditions.
