VSI stands for “Vapour Sequential Injection”. The VSI system is the most advanced vapour injection system on the market. It was originally developed by Prins and has now been completely redesigned to suit advanced modern engines. All components used in the VSI system satisfy the most demanding regulations and certification standards.
The VSI system is based on the principle of converting liquefied petroleum gas (LPG) or natural gas (CNG) to vapour form before sequentially injecting it into the engine. We also offer solutions for cars with a direct injection fuel system!
- High-quality components
- Unique diagnostic software
- Optimal performance
- Reduced emissions
No noticeable difference compared to running your vehicle on petrol!
Is there a VSI system for your car?
We can convert all cars with an MPI (multipoint injection) engine to LPG or CNG! The number of LPG and CNG systems for cars with a direct injection fuel system is also growing rapidly.
Thanks to our extensive range of products, we lead the market. We know from experience which system works best for a particular engine. Find out which system suits your car best by searching our database.
