Methanol port injection can retard the ignition timing in premixed diesel combustion with suppression effect of low temperature oxidation, and smooth premixed combustion neat top dead center is established. However, with increasing in quantity of diesel fuel, a required quantity of methanol to suppress the low temperature oxidation increases and the high temperature oxidation becomes rapid due to higher concentration of premixed methanol and diesel fuel. In the case of this experiment as the injection timing of diesel fuel is fixed at 40℃A BTDC, the maximum BMEP is limited at 0.25MPa due to knocking without methanol. The combination of methanol injection and EGR can expand the maximum BMEP to 0.55MPa and realize smokeless and low NO_x combustion in this range.
