Abstract

The impacts of engine operating parameters, including intake charge temperature, fuel-air equivalence ratio and engine speed, on methanol HCCI combustion and performances were investigated on a modified diesel engine. The results show that the intake charge temperature is the most sensitive parameter of methanol HCCI combustion. The engine speed scopes are changed with boundary conditions, and the optimum speed increases gradually with equivalence ratio. But, the equivalence ratio just has a little influence on thermal efficiency. Moreover, CA50 is more sensitive to the boundary conditions than CA10, and the appropriate combustion phase for methanol HCCI engine may be within 8°CA for CA50 and within 11°CA for combustion duration.
