The HC emissions are increased remarkably when the mixtureconcentration becomes too lean or too rich.
当首循环混合气浓度过浓或者是过稀时，瞬态hc排放迅速增加。

The effect of the mixtureconcentration, temperature, and ratio of alum to rosin on the rosin-alum size efficiency was studied theoretically.
本文就混和物浓度、 温度以及明矾松香的比例对明矾- 松香胶的尺度效应进行了理论上的研究。

These factors are mixtureconcentration, ignition advance Angle, engine speed, temperature of cooling water and carbon deposit on the SUrfaces of the combustion chamber, etc.
