在轿车动力装置中,火花点火发动机在全世界范围内占着优势,其原因主要是:1)平均有效压力高(>10);2)最大转速高而扭矩大,升功率大(>6000转/分);3)重量轻,体积/功率比小;4)运转平稳、噪声低;5)单位功率成本低;6)可燃用汽油、液化石油气、醇类(甲醇、乙醇)、天然气、液化天然气和氢等多种燃料。就上述优点而论,没有一种其它类型动力装置能与火花点火发动机相比。
In the car power plant, spark ignition engines dominate the world, the main reasons are: 1) the average effective pressure is high (> 10); 2) the maximum speed and high torque, high power (> 6000 / Min); 3) light weight, small volume / power ratio; 4) smooth operation, low noise; 5) low unit power cost; 6) combustible gasoline, LPG, alcohols (methanol, ethanol), natural gas, Liquefied natural gas and hydrogen and other fuels. In the light of the above advantages, no other type of power unit can be compared to a spark ignition engine.
