A Typical Conversion
A modern LPG Conversion as supplied by Greenfuel is a high quality well engineered piece of technology. All systems comply with EU standards and in many cases we use exactly the same components used by car manufacturers as original equipment. Most of us do not need to know exactly how the systems work. The following is therefore a non-technical guide to what you need to know. Read more technical information.
The System
An LPG conversion is simply a secondary fuel system for your car that enables it to run on Liquefied Petroleum Gas. The primary fuel system (normally petrol) is always retained. Where modern conversions differ from those of just a few years ago is that they use the car's existing engine management system to control precisely the right amount of LPG delivered. Older systems do not use the cars existing electronics and seek to control the amount LPG supplied to the engine mechanically, this is not appropriate for modern engines and is unreliable. Greenfuel do not fit any form of older system to modern vehicles.

A second set of fuel injectors is fitted; these are used to deliver the LPG into the engine. The injectors are fed with gas from a special pressure reducer and controlled by an electronic link to the vehicle's own engine management system, monitoring the enginersquo;s requirements and immediately adjusting the fuel delivery for maximum performance and economy. When fitted to the vehicle these components are virtually unnoticeable.
On the Dashboard
Even though the vehicle will automatically default to LPG, a small switch & status unit will be added to the dashboard. The lights along the top indicate the fuel status, and the rocker switch position indicates whether the car is running on gas or petrol. To switch between fuels simply press the switch (whilst driving) and the engine will switch between gas & petrol.
Filler Point
In order to re-fuel the tank a filler point is added to the outside of the vehicle. This takes the form of a black, or colour coded flush mounted cover approximately 75mm in diameter that can be opened to reveal the filler connector. The mounting position can be almost anywhere towards the rear of the car. If body mounting is not desirable then tow bar or chassis mounting brackets are possible.
The Gas Tank
The gas tank is obviously the largest component in an Autogas conversion and is therefore the most difficult to place. Most tanks simply fit in the spare wheel compartment, in place of the spare wheel. If preferred customers can choose a larger tanks. Greenfuel supply Tyre Weld, a first-aid liquid puncture repair kit which is faster, easier and safer than changing wheels.
