How LPG works
Liquefied Petroleum Gas often called Autogas is made up of propane and butane. It is a by-product of oil extraction and refinery operations. The nature of the fuel means that it burns cleaner. LPG has gained support as an environmentally friendly fuel in respect of both global warming and air quality, particularly in towns and cities where vehicles cause specific pollution and noise.
With in regards to noise, LPG vehicles can reduce decibels by as much as 50% compared to diesel vehicles.
The latest conversions capable of adapting your car to run on LPG, are quite complicated and take advantage of the latest emission control technology fitted to most modern petrol cars.
All LPG conversions have a storage tank, usually in the form of a doughnut tank fitted in the spare wheel well or a cylinder tank fitted in the boot of the vehicle.
LPG is fed through a pipe as a liquid to the engine compartment and then transformed into gas by a vaporiser and metered into the inlet manifold. All modern conversions use the same basic principle, using injectors fitted directly into the manifold. When LPG is being used, the petrol injectors are switched off.
A switch is fitted usually on the dashboard. This switch lets you know how much LPG you are carrying and also allows you to switch over from LPG back to petrol.
Is a LPG conversion environmentally friendly?
Liquefied petroleum gas cars produce up to 82% less nitrogen oxide and 30% less CO2 emissions so yes.
