ملخص المقالة :
Gasoline causes engine knock in higher compression ratios due to having lower spontaneous ignition temperature. Natural Gas (NG) has a higher octane number and is a proper fuel in terms of anti-knock properties; however, using it as the engine fuel results in a decline in the power of the engine and increases the emission of some exhaust gases due to lower burning velocity and gaseous nature.
