For our inaugural blog post, we’ve looked to provide some technical “dos and don’ts” on the nitty gritty of autogas conversion, or LPG installation as it is commonly referred to. Its specificity means that, for the most part, it will make the most sense to existing LPG installers and other members of the automotive industry around London (a principal service area of ours) who might be curious about the process of retrofitting a vehicle in such a way.
But, we also hope that everyday customers intrigued with the intricacies of the services we provide – not just installation, but LPG servicing and repair – will see that when we say we’re genuine LPG specialists, we really mean it! If you’re in London and considering the benefits of an LPG / autogas conversion, then call our team on 0208 336 5959. Our friendly team would love to answer your questions.
Rules LPG Installers in London & the wider UK Should Follow
- LPG installers should always place the ECU in a spot that can be easily accessed by the outside air channelled through the radiator, next to the battery on the outer side of the engine housing.
- Any autogas conversion carried out in London or the wider UK shouldn’t see the ECU repositioned too close to heat sources. This can lead to a number of significant issues that can’t be fixed over the course of standard LPG servicing; they would require full-fledged repair by LPG installers.
- Likewise, all good LPG specialists know not to place the ECU with connector facing upward, as this causes issues with condensation. Instead, the ECU should be placed vertically with connector faced downward (optimal) or failing this, in the horizontal position.
- By no means should the reducer be placed at a higher point than the radiator. This could prevent water flow and eventually damage the membranes. Instead, place it below the top of the radiator, so that air inside the pipes can be properly purged.
- LPG installers carrying out an autogas conversion for a London client should ensure the hose connecting the map engine vacuum isn’t overly long; less than 60cm is ideal. Any longer and performance during periods of rapid acceleration can severely suffer.
- Injectors should not be tilted with coil positioned downward, as this can mean residual gas stagnating and blocking the shutter. Position them upright so that the flow of residual gas into the engine is not disrupted. Also, ensure that the injector pipes are less than 10cm long.
- Try to keep the lengths of pipes similar, as too much variance can cause what LPG specialists refer to as asymmetric injection, which can lead to system instability. Splitting the pipes into two pairs is one way many London based LPG installers achieve this.
- If your vehicle has an old or unclean spark plug, even if it’s currently running fine in petrol mode, we urge you to have it replaced. A worn spark can cause issues in gas mode.
