air inflow

The air inflow in each circle is basically constant, while the diesel engine is working. So each working condition is adjusted to change the output power, by means of changing the oil injection ( changing the density of the gas mixture).

柴油发动机工作时每个循环的空气进气量基本上都是恒定的，要改变输出功率，只有通过改变喷油量（即改变混合气的浓度）来调节各个工况。
