A unique and future-proof CNG system for the latest direct injection (DI) engines up to Euro 6D emission standards.

The heart of the revolutionary VSI-3 DI CNG system is the new VSI-3 AFC computer with integrated DI injector emulation and full 'limp-home' functionality; ensuring overall system control, safety and efficiency.

This AFC is compatible with DI and DI+MPI engines. The number of CNG systems for cars and vans with a direct injection fuel system is growing rapidly. Thanks to our extensive range of VSI-3 DI systems, Prins is a pioneer in this market.
