Compared to competitors in the market, Prins offers reliable fuel systems for a wide range of vehicles. These VSI-DI systems consume very little petrol (< 5%), and are suitable for both the latest car types and cars that have already been on the road for several years.

The VSI-DI system is based on the principle of converting liquefied petroleum gas (LPG) or natural gas (CNG) to vapour form before sequentially injecting it into a DI engine.
