VSI System

VSI is an abbreviation for "Vapour Sequential Injection". The VSI system is the most advanced vapour injection system available on the market. With the VSI system there is no difference between driving on LPG or with petrol. With the VSI system, Prins strives for optimal emissions and cost reduction.

The VSI system is developed in close cooperation with Keihin Corp of Japan, one of the world's leading injector manufacturers and a name that stands for OEM quality and reliability.

The VSI system is fully integrated by way of a "master - slave" method with the vehicle ECU, making it (E)OBD compatible, therefore oxygen sensor signal emulation is not required.

The key components of the system are all of OEM quality and specially designed for LPG applications. All components comply with the strictest regulations and certifications. The installation of the components is very easy due to the compact design of the components.

The dedicated diagnostic software is unique and enables fine tuning the VSI system for optimal performance and emission reductions.
