TY - JOUR TI - Combustion characteristics of different premixed methanol charge compression ignition combustion modes AU - Zhu Jianjun AU - Li Peng AU - Geng Xi JN - Thermal Science PY - 2020 VL - 24 IS - 3 SP - 1609 EP - 1615 PT - Article AB - 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.
