Combustion characteristics of different premixed methanol charge compression ignition combustion modes

ABSTRACT
This paper proposes two dual fuel combustion modes for a diesel engine based on two alternative fuels and explores the influence of engine compression ratio on combustion and fuel economy characteristics under heavy loads. The results show that reducing the compression ratio can reduce the pressure rise rate of the combustion mode of methanol premixed charge induced ignition, owing to a decrease in the brake thermal efficiency.
