All the components as well as the installation, repair and maintenance of LPG systems are covered by mandatory standards and other regulations.
For example, in all states and territories only a business that meets special licensing requirements is permitted to install, repair or adjust a car LPG system. Search for a licensed installer near you.
- Before you convert your car, contact your vehicle’s manufacturer to find out whether it’s suitable, and whether the conversion will affect the car’s warranty.
- Your transport authority has information on particular requirements in your state or territory. It can also give you details of licensed installers in your area. You must inform them once your car has been converted.
- While it’s unlikely you’ll pay a different insurance premium for a converted car, you should contact your insurer to make sure. In any case, you must inform them once your car has been converted.
The conversion usually consists of the following main components:
Tank: while you can convert your car to run on LPG only, the LPG system is usually installed in addition to the fuel system (dual-fuel mode), greatly increasing your car’s range. LPG tanks are considered to be as safe if not safer than petrol tanks in an accident.
Fuel lock valve: prevents the flow of gas when the engine stops.
Vaporizer regulator (converter): regulates the outlet gas pressure according to engine demands.
Air/gas mixer: mixes LPG vapour with air for combustion.
LPG control processor: operates in conjunction with the car’s on-board computer to accurately meter the amount of gas for increased economy.
A dual-fuel conversion must ensure that all emission control, engine control and engine management systems and devices remain operational. You’ll have to use the fuel system every now and then to keep it functional and safe — recommendations range from 10% to 30% of the time.
