LPG is a economical substitute for petrol and stands for Liquefied Petroleum Gas, a mixture of propane
and butane which is a by-product of crude oil. A suitable, safe system
is needed for storage and adjusting the LPG to the engine.
Therefore an
LPG system involves:
- LPG storage tank with safety devices to shut off the tank when the engine stops
- Vaporiser/ regulator to vaporise the liquid and regulate the pressure of the LPG
- A main flow adjuster to adjust the LPG flow
- Mixer to mix the LPG with the air
- A petrol shut off system
LPG is normally cheaper than petrol, but there are more advantages:
- LPG is a "waste" product which otherwise would be burned off. So
therefore it's a more environmental friendly fuel.
- The internal engine pollution is less.
- The knock resistance is very high (LPG approx. 100 octane, regular-grade petrol approx. 95 octane and premium-grade petrol approx. 98 octane)
- LPG is easy to store as a liquid at approx. 6 bar.
After installing an LPG system the fuel consumption may rise 10 up to 15% and the power will drop 10 up to 30% according to the quality of your system.
The key component for high power and low fuel consumption is the mixer.
The smaller the mixer the higher the power loss. For this reason we supply systems for small engines starting from 4bhp with small mixers and very large ones for big
powerful engines (25mm up to 75mm venturi size).
Most manufacturers supply mixers up to 35mm or sometimes 40mm venturi size. To make it possible to use very large mixers you need a very well designed system.
We
gather components which will result in a balanced system to give minimal power loss and the best mileage.
We
also have high performance (racing) systems suitable for engines up to 400bhp.
In this case the fuel consumption might be slightly higher.
