What’s LPG Autogas?

Autogas is the term used to describe LPG (Liquefied Petroleum Gas) used as an automotive fuel. LPG is a blanket denomination covering propane and butane, two naturally occurring gases which are easily converted to liquid form through the application of moderate pressure. LPG is primarily derived during the extraction of natural gas, and is also produced in refineries. It is a highly versatile energy source with hundreds of applications in the home, in industry, agriculture, and – of course – as an automotive fuel. Often under exploited in the past due to unsustainable practices such as flaring and venting, it is increasingly being recognized as a unique and valuable energy resource.

post_370x192Powering 10 million vehicles across Europe and accounting for almost 4% of the passenger car fleet road transport fuel mix, Autogas is already the leading alternative fuel in the EU. Through a joint effort on the part of industry and public authorities, there is potential for rapid and considerable growth, particularly in the passenger car sector. Autogas could account for a 10% share of Europe’s passenger car fuel mix by 2020. This would yield considerable benefits for governments, individual citizens and society in general.

Environmental Benefits

With an increasing need to protect the world we live in, it’s good news to find that Autogas offers an option to help reduce harmful emissions.

Frequently asked questions about LPG Autogas

There are a variety of different kit and tank types that will suit most makes and models of petrol powered vehicles. Contact us to find out if your car is suitable for Autogas conversion. Diesel conversions are also available for trucks/HGVs.

The LPG Autogas systems in today’s modern vehicle are designed to be very safe. They are safe in use, safe to repair and safe in a vehicle accident situation.

An Autogas system has a number of important safety features including:

  • A welded steel pressure cylinder which is stress-tested to many times its normal operating pressure prior to being installed.
  • Two electronically controlled shut-off solenoids (on cylinder and under bonnet) which stop the flow of gas to the engine if the engine stops for any reason.
  • Pressure relief valves, for the tank and the system, to prevent any pressure build up that may damage the system or be hazardous.
  • Double back-check valves to ensure gas tight filling.
  • Sealed compartments and venting around valves and pipe-work to ensure no LPG enters the interior of the vehicle

LPG is one of the most environmentally friendly automotive fuels around, offering a tremendous advantage in towns and cities where pollution is a problem. With an increasing need to protect the world we live in, it’s good news to find that Autogas offers an option to help reduce harmful emissions.

Tests have shown that Autogas emits:

  • 10-12% less CO2 than petrol
  • 53% less NOx than petrol
  • 120 times less small particle emissions than diesel

A good conversion using quality components, properly installed and adjusted, should make the engine perform just as it does on Petrol. There has to be some power loss (LPG is 15% less potent when measured against petrol) but this is only evident at the highest part of the RPM band. When driving a converted vehicle with a larger engine it is very difficult to find any difference in performance. Vehicles with smaller engines might show the power reduction more clearly but we are still only talking about a minor amount toward the top of the rev. band. Not a big deal for most drivers as we rarely ‘red line’ the engine on today’s roads.

The LPG tank and fuel pipes are fitted with numerous safety devices. The gas flow will automatically stop if the pipes are damaged or the engine is not running. If the vehicle catches fire, the gas tank pressure is controlled via safely venting excess pressure which will prevent the tank from rupturing and causing further damage. Tanks are made of thick steel.

No. Autogas is a cleaner burning fuel that doesn’t contain acids or leave behind carbon deposits. It can, in fact, increase the life of the engine.
