Research on the antiknock and emission characteristics of mixed fuels with alcohol and its derivative

摘要

Unleaded gasoline has began to being used in the automobile industry in China. This paper focused on the discussion of the antiknock and emission characteristic of gasoline mixed with alcohol and its derivative. The result showed that the mixed fuel alcohol and its derivative can improve the fuel characteristic in antiknock and emission. Below the range of 20 percent mix ratio, the higher the mix ratio, the better the improvement. Of all the mixed fuel discussed in this paper, the mixed fuel with methamol is better than any others in the CO, NOx and HC emission.
