Gas conversion, also known as LPG conversion, is a viable means to modify a car from a petrol system to an LPG fuel system, where petrol becomes a secondary fuel source. LPG is a cheaper alternative to standard petrol, although both are fossil-based fuels, LPG is far cheaper than both petrol and diesel, working-out at roughly half the cost. The reduced price of gas is due mainly to governments placing fewer taxes on LPG fuel; this is because it produces fewer environmental pollutants than other fuels. Throughout the EC, including the UK, governments are encouraging gas conversion for petrol cars. It is easy to refuel an LPG tank, over 1200 garages provide LPG fuel to customers around the UK 鈥?and this number is increasing year on year, as more people take the plunge and convert their cars from petrol to gas. The majority of fuel conversions undertaken in the UK are 鈥 榖 i-fuel 鈥?conversions. This means that the car is able to run on the original fuel, petrol, but also on LPG. Once the car conversion has been carried out you have the option of which fuel type to use, but normally the car will run on petrol until the engine is warm, then automatically switch to LPG once it has been running a few minutes 鈥?there is an option that allows you to switch off this automatic mechanism, but this is largely unwarranted as LPG is cheaper, more efficient and generally better for the vehicle. Because of this bi-fuel system, if you were to run out of LPG before you find a refuelling station, you will benefit from the reserve-tank effect of the original petrol tank 鈥?this reserve tank feature means that you can drive for a much more extended period than you would with a standard petrol car. Generally, the LPG fuel tank is placed in the boot of the car, in the section that contains spare wheel. Vehicle safety is not compromised with a gas conversion, servicing, maintenance and MOT continues as before. LPG is generally better for the vehicle; the gas is less acidic and abrasive than standard petrol, thus causing less damage than its more corrosive counterpart does. Thus, you save not only petrol costs, but also on engine wear 鈥?whilst at the same time increasing engine efficiency. As discussed above, LPG car conversion involves the addition of an LPG tank, usually fitted in the boot, and a fuel choice switch that enables the drivers to change manually the source of fuel for the car. Additionally, an LPG converted car needs to have a filling system (the position of which is subject to legislation), the nozzle used at the pumps is not universal between countries and you may need to buy a specialised adapter if driving abroad. LPG tank sizes vary and are suited to the size, make and model of the car being converted. The various elements involved with a gas conversion will be explained thoroughly before work is started on the vehicle. Clarification of key points will ensure a comprehensive understanding of the process is established prior to the commencement of work. http://www.prinsautogasuk.co.uk is the right shop these kind of services.
