代用燃料发动机碳烟排放的试验研究

Experimental Study of Soot Smoke Emission for Alternative Fuel Engine

针对发动机机燃用LPG(液化石油气)和柴油混合燃料的碳烟排放问题进行了研究。发动机的碳烟排放量随着燃料中LPG所占比重的增加而迅速下降,但在掺比达到一定值时又开始有所上升,只要控制掺比在合适的范围内,就可以明显减少内燃机的碳烟排放。

The paper studies the soot smoke emission of dual - fueled engine burning LPG/diesel. The results indicate that the soot emission of the engine decreases while the proportion of LPG in the fuel burned by engine increases rapidly, but shall begin to increase beyond a certain proportion. Soot smoke emission can be reduced significantly once the diesel/LPG proportion is limited within a correct area.
