The Prins Dieselblend Dual Fuel system is an innovative fuel system. In diesel engines, this system makes it possible to substitute a part of diesel by cleaner and cheaper (bio) LPG, CNG or LNG.
The injection system uses advanced electronics and software to combine the two fuels, and to create an optimal mix between diesel and the alternative fuel (LNG/LPG/CNG). The Prins Dieselblend AFC unit (Alternative Fuel Controller) calculates realtime the amount of diesel fuel that can be replaced. The AFC also calculates the amount of gas that needs to be injected to guarantee the same performance (power and torque) as achieved with the original diesel fuel. This reduces consumption and operating costs without affecting the engine life and performance.
- High-quality components
- Unique diagnostic software
- Optimum performance
- Reduced emissions
Depending on the type of vehicle and your requirements as a customer, several design options are available for the gas tank configuration.
Is there a Dieselblend Dual Fuel system for your vehicle(s)?
The Dieselblend Dual Fuel system is suitable for all medium- and heavy duty diesel engines. Passenger cars on diesel cannot be converted with this system.
The following are the main components that are added to your vehicle when an LNG conversion is installed.
The components that make up our Dieselblend system are shown below. The main components meet the same standards as OEM parts and have been specifically developed for LPG, CNG and LNG systems. They satisfy the most demanding regulations and certification standards.
