Auto Gas Conversion
Automotive LPG or Autogas is the most accessible alternative fuel. Driving an LPG vehicle is safe, easy and, in many countries, considerably cheaper than driving a petrol or diesel model. LPG also emits less CO2 (Carbon-dioxide) and fewer other emissions such as NOx (Nitrogen Oxide).
Autogas first came into light in the mid 1930’s, LPG had been discovered in Germany only a few years earlier as a condensate when compressing refinery off-gas to extract gasoil. It was being sold in cylinders as propane and butane or as a less refined mixture of both components. At the same time countries with a low supply of oil like England and Germany began experimenting with alternative fuels in search of alternatives to fuel their growing car fleets. Ultimately striving for self-reliance, no option was to be left untested. Among others, experiments were conducted with natural gas (methane) and LPG and it was discovered that vehicles running on LPG where more efficient than as it combines low cost and emissions with compared to traditional fuels.
There are four types of Autogas conversion systems:
Vapour phase injection (VPI)
Liquid phase injection (LPI)
Liquid phase direct injection (LPDI)
