摘要

A one-dimensional model of a hydrogen internal combustion engine was built, and the effects of exhaust gas recirculation technology(EGR) and Miller cycle technology on the suppression of knocking and nitrogen oxides(NO_x) generation were simulated and analyzed. At last, these technologies were combined to explore the maximum achievable compression ratio and the best NO_x emission performance. The results show that EGR technology is more effective in suppressing NO_x production, while the Miller cycle is more effective in suppressing knocking. Finally, the compression ratio of the internal combustion engine can be increased from 10.0 to 18.4. The efficiency is reduced by 8.0% to 44.87%. And the NO_x emissions are reduced by 26.2% to 1.937 g/(kW•h) at the same time.
