Prins Dieselblend System

LPG/CNG/LNG dual-fuel conversion for diesel engines

Prins Dieselblend

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

By monitoring parameters such as engine speed, turbo pressure, amount of diesel injected, position of the accelerator pedal, engine torque, and the temperature of the coolant, the system determines the optimum balance between diesel and LPG/CNG/LNG.

The key components of the system are OEM quality and specially designed for these applications. All components comply with the strictest regulations and certifications, and their compact design makes installation very easy.

The dedicated diagnostic software is unique and enables fine tuning the DieselBlend system for optimal performance and emissions reduction.

For the storage of the LPG, CNG, or LNG there are different tank options available, including the Westport iCE PACK™ LNG Tank System.


With high quality components, refined adjustment and worldwide professional support, Prins offers a reliable, dedicated system. Drivers will experience the same driving performance as always.
