Liquefied petroleum gas is nowadays mostly used in petrol engine vehicles. The verity in rear usage of LPG is it doesn’t harm the engine of your automobile. Countless benefits to the engine are endowed with the use of LPG. It is a dirt free burning gas, without rooting deposits to the combustion chamber of the engine concerned. The octane rating of the gas is radically elevated than the petrol, hence it can put up with higher compression ratio which is conductive to higher competence. This can only be accomplished in few fanatical engines and not in few converted engines. The reason on which it works well in dedicated engine is that the custom engine has to switch back to petrol mode once the gas in the chamber allotted is exhausted.
Nevertheless, the pristine burning has the characteristics of lesser maintenance and dearth of mal disturbance from the cylinder to cylinder and cycle to cycle. This will result in better performance in both fuel economy and as well as the emission. There is no menace of benzene and other carcinogenic aromatics in the exhaust when compared to the dreaded lead fuel, since the level of octane is high naturally. As per the intensive research in U.S on substitute fuel technology, the usage of propane accounts the largest in alternative fuel technology.
In detail, there are two types of light duty vehicles. This accounts in dedicated to propane fuel technology, where the engine operates exclusively on LPG and the dual fuel. Dual fuel is a technology in which the factory made engines are prepared for the use of both gas and petrol. The bulk of LPG is considered as Propane is generally termed as varying quantities of ethane and butane. This can be liquefied at ambient temperatures by pressuring it to moderate range of 25 to 125 psi (Pollution Standard Index) depending on the temperature. These pressures can be contained safely in simple thick wall steel tanks. This technique is entirely contrast to natural gas where it must be stored in reinforced tanks or it must be chilled to minus 260 F and stored in double wall cryogenic tanks.
