The hydrous ethanol steam was burned or mix-burned on a gasoline or diesel engine with the intake premixing method.

This paper presents a new method of detecting whole premixing combustion air-gas ratio, describes the principles and operational steps of the method, and analyzes its application prospect.

The results showed that the blending method of premixing masterbatch of short polyester fiber and EPDM, and then blending with PP was the best method.
