Prins Autogassytemen BV, a group company of SHV Energy, is a global supplier of alternative fuel systems and components for automotive, bus, HDV, industrial and marine applications with distribution channels in more than 50 countries.

Prins obtained world’s first R115 certification for its LPG system with direct LPG injection called Direct LiquiMax System. The Prins Direct LiquiMax system complies with EURO-5 and EURO-6 emissions standards.

The Prins Diesel blend system makes it possible to convert diesel engines (in trucks) to dual-fuel engines by means of replacing a certain quantity of diesel by LPG or CNG or LNG or Biogas. The Diesel blend system is installed beside the original motor management system, and in principle it is suitable for all diesel engines (as from Euro 3). The system communicates (read only) with the ECU via CAN-bus to ensure fully computer-controlled injection of the correct amount of gas, depending on the specific characteristics of the diesel engine.
