Abstract

This study investigates the effects of adjusting intake guide flappers, EVVT, and split injection on the performance of a four-cylinder, four-stroke methanol direct-injection engine. The results show that installing the optimal transverse flapper 4 and longitudinal flapper 5 leads to a reduction in CA5-IG and CA90-CA10, an advance in CA50, a decrease in CO and HC emissions, and an increase in NOx emissions. After optimizing the ignition timing, the BSFC can be reduced by 1.5 %. Installing the optimal flappers enhances the reduction in BSFC and mitigates the increase in COVIMEP caused by delayed EVVT. With the installation of the normal flapper, flappers 4 and 5, the lowest BSFC occurs at an EVVT of −10°CA. Meanwhile, BSFC is reduced by 1.1 %, 1.5 %, and 2.0 % compared to −25°CA, while COVIMEP increases by 48.8 %, 36.2 %, and 13.9 %. Installing the optimal flappers enhances the improvement of split injection on combustion performance, fuel economy, and cyclic variation. With the installation of the normal flapper, flappers 4 and 5, the lowest BSFC and COVIMEP occurs at the second injection ratio of 10 %. Meanwhile, compared to single injection, BSFC decreases by 0.2 %, 0.9 %, and 0.6 %, while COVIMEP decreases by 18.5 %, 32.6 %, and 31.9 %.
