In order to study the influence of the fuel delivery advance angle and the methanol energy proportion on the combustion and emission performance of a dual-fuel engine, polyoxymethylene dimethyl ethers (PODE) were used to ignite the methanol premixed gas. The results show that with increasing the methanol energy proportion, the peak of in-cylinder pressure gradually decreases, the maximum pressure rise rate and the peak of heat release rate at the low speed were increased first and then decreased, the peak of pressure rise rate and the peak of heat release rate were both increased at high speed. Proper increase the fuel delivery advance angle could improve in-cylinder combustion. With increasing the methanol energy proportion, the emission of CO, THC and formaldehyde were gradually increased, the emission of NOx was increased first and then decreased. Appropriate postponement of the fuel delivery advance angle would reduce emissions from dual-fuel engines.
