摘要：To realize the clean combustion in the automotive engine, multi-injection strategy with two kind of fuel has attracted the attention of technicians due to the flexibility to control the concentration and activity stratification of mixture in the engine cylinder. This paper shows the effect of various injection strategy of highactivity fuel on the emission. Results showed that adjusting multiple injections strategy had the ability to optimize the stratification of the mixture and to decrease the production of emission, such as NOx, Soot and UHC. The emissions, either soot or NOx will increase in the cases of large ratio at early or late injection at Multi-injection strategy.
