石油氣(LPG)引擎工作原理

石油氣車是採用電油引擎的，因為兩種燃料的爆炸力接近，所以大家都可以共用壓縮比較低的引擎，壓縮比較大的油渣引擎則不適合。如果油渣引擎換上石油氣或電油作燃料，引擎本身不能支持強大的爆炸力。

usually, the LPG engine is base on a Gasoline engine ,coz the compression ratio and the operation steps very similar , both needed the spark-plugs and the fuel mixing with the air while the engine doing intake step ~ the Diesel engine's compression too high and the igniton system is totally different, if you want the diesel engine goes LPG , its a big job, in Japan ISUZU offer some model of truck in LPG and CNG ~ their engines all from Diesel's verison , ofcoz the Compression , the ignition system and the fuel system tuned/changed already !
