Natural gas is one of the world's most abundant fossil fuels and currently supplies over 25% of energy demand in U.S. The primary uses of natural gas are for space heating electricty generation and industrial field . LPG (Liquefied Petroleum Gas) and CNG (Compressed Natural Gas) are more famous and popular alternative fuels for engines. By improving of entering air inlet turbulence and high voltage coil, it would be possible to increase flame speed on gas made. In present paper an experimental study on LPG and CNG fueled engine with effect of spark power and advance on performance have been done.
