Our Diesel Blend systems
The Prins Diesel Blend 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). Our Prins Diesel Blend 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.

All our Diesel Blend systems offer:
- High-quality components
- Unique diagnostic software
- Optimum performance
- Reduced emissions
Depending on the type of vehicle and your requirements, several design options are available for the gas tank configuration.

Why Diesel Blend?
Here are some of the reasons to change to a Diesel Blend dual fuel system:
- Reduction in the fuel costs per mile
- Reduction of exhaust emissions
- Easy to install
- No drastic adjustment to the engine necessary
- Short payback time
- At all times possible to switch back to 100% diesel operation
- Not dependent on the alternative fuel infrastructure
- No downtime should the diesel blend system fail
Savings
Savings depend on:
- Vehicle fuel consumption
- Mileage
- Blend rate
- Type of fuel LPG/ CNG
- Local fuel prices
The saving is done through a percentage of diesel replaced by a cheaper alternative fuel LPG/ CNG. The higher the blending rate, the higher the savings.
The savings also depend on the price differential between diesel and LPG/ CNG and are dependent on local fuel prices.
Test results also show an increase in engine efficiency, seen especially at higher engine load.
The more miles you do, the greater the savings!
