Based on a large six cylinder intake port injection ignition M100 methanol engine, the effects of injection timing on engine performance at 1100 r/min and 100% load were studied using a combination of bench tests and CFD fluid simulation software CONVERGE. In this paper, five different injection timings (449, 439, 429, 419, 409°CA ATDC) are set for simulation calculations. A comprehensive comparison of the simulation results shows that in terms of combustion, the forward movement of the injection timing can effectively improve the combustion quality of the engine. As the injection timing advances, the peak combustion pressure, cumulative heat release, and peak temperature in the cylinder gradually increase, and the phases corresponding to CA10, CA50 and CA90 gradually move forward. The combustion duration gradually decreases, the quality of the incylinder mixture gradually increases, and the ignition speed gradually accelerates. In terms of emissions, the forward shift of fuel injection timing can effectively improve the engine's CO, HC and SOOT emissions, but the NOx emissions have increased.
