Burn
Burning, as the name suggests, refers to the thin fuel in the air when burning.When the air -fuel ratio is greater than 18: 1, the combustion state in the cylinder can be called thin burning.The biggest advantage of thin combustion is that the combustion efficiency is high, reducing fuel consumption while increasing the power output of the engine.Because under the condition of thin combustion, it is more difficult for mixed air to ignite than under the theoretical air -fuel ratio, and the deflagration is not easy to occur. Therefore, a high compression ratio can be used to improve the heat energy conversion efficiency.In addition, gasoline can be fully burned in excessive air, so with the support of these conditions, you can "squeeze" the energy of each drop of gasoline as much as possible.
