An innovative method is developed for achieving HCCI-DI combustion without any major engine geometry modification. Many control strategies have been reported in literature, in spite of that even today no HCCI combustion engine is available on commercial basis. Pilot and main fuel injection strategy is used as a control strategy in this work. Our developed technique is a low cost alternative to conventional CRDI pumps which can be implemented readily at least for rural application engines (where cost of the system is more important than any other aspects) to reduce emissions. Using this new technique a stable HCCI-DI combustion was achieved for a wide operating range. To realize the effectiveness of this developed experimentation technique, a detailed combustion study at various operating conditions were investigated using commercial diesel as fuel.
