Very simply, autogas or auto LPG is Liquid Petroleum Gas (LPG) used for automotive purposes. LPG is an energy that has many applications such as domestic water and space heating, cooking and industrial heating.
Lessons in AutoGas
LPG is a gaseous hydrocarbon that is stored under pressure in liquid form. We are talking convenience and portability here. The gas is liquified under moderate pressure and expands to approximately 270 times its liquid volume when it is allowed to revert to vapour. This characteristic enables LPG to be stored as a compact liquid but burnt as a dry, gaseous vapour.
LPG is transported and stored in liquid form. When an auto LPG car is refuelled with LPG, it retains its liquid form until the fuel is actually needed by the engine.
Most auto LPG cars in Australia run on a vaporised gas carburettor system. Electronically controlled pressure regulator and mixing units, combine the LPG with air prior to its injection into the engine. This current technology is known as second generation.
Existing petrol vehicles can be converted to LPG through the installation of a specially designed autogas kit, which includes fill valves, tanks, fuel lines, pressure regulator, mixing unit, actuator and an electronic unit. This enables you to use either petrol or LPG to run your vehicle at any time. We call this a dual fuel system.
Running a vehicle on LPG couldn't be easier - simply press a button on the dashboard. A quality conversion will ensure that you feel virtually no difference in performance. Apart from saving money, the added bonus is that with dual fuel, you’ll be able to run your car for up to 1000 km without the need to stop to refuel.
It's pretty simple to convert a car to run on autogas and compared to the fuel cost savings not that expensive to install. Compared to the whole of life cost savings, the conversion cost is surprisingly low.
If you’re interested in running a vehicle on autogas, you have 4 options:
- Convert an existing petrol vehicle to autogas by installing an LP Gas conversion kit (called a retrospective or after-sale conversion)
- Purchase a second hand car run on dual fuel
- Purchase a new car with a dual fuel system (the factory-fitted kit option)
- Purchase an LPG dedicated vehicle – (car designed and optimised to run only on autogas)
Both dedicated LPG vehicles and LPG conversions are now available in the Australian market. Conversion costs will depend upon the make of car.
