With a history going back over 50 years, LP Autogas stands for service, quality and reliability. We enjoy providing our customers with professional support in both commercial and technical areas. In addition, we promote a better position for automotive LPG in the engine fuel market. To do this, we take part in various national and international industry organisations.
LPG stands for Liquified Petroleum Gas. LPG is a by-product of refining crude oil. In addition, LPG is also harvested in large quantities as a naturally occurring gas from natural gas fields. This LPG is relatively cheap to produce, because it needs fewer additions to make it suitable as car fuel.
LPG is a mixture of propane and butane. Under pressure, it changes easily from gas to liquid. A car gas tank contains liquid LPG; if the pressure is removed, the LPG changes to gas again. When it changes, its volume increases 250-fold, which creates a strong gas pressure that propels the gas towards the engine, so you do not usually need a pump.
LPG has a high octane rating compared to crude petrol. This is important for the compression of the fuel in the piston chamber. The higher the octane rating, the easier it is to compress a fuel and the greater the power stroke in the piston after ignition. In contrast to crude petrol, LPG does not need any octane-increasing additions. LPG does have one additive: an added odour (ethyl mercaptan) because the gas itself is odour-free and colour-free by nature. This addition of odour means that you will smell the LPG in the unlikely event of a gas leak.
