Dual fuel



Heavy-duty trucks and buses account for about one-third of NOx emissions and one-quarter of PM emissions from mobile sources. In some cities, the contribution is even greater. The fine particles in diesel exhaust (known as particulate matter) pose serious health risks. 


Despite its name, natural gas can also be supplied in liquid form to facilitate its transport at -162ºC in cryogenic tanks. Among its many environmental benefits is the fact that it is neither toxic nor flammable, minimising risks posed by old fuels.

LNG is the variety of natural gas indicated for long haul transport due to how this liquefied form allows for the drastic reduction of its volume, allowing for optimised yield of the tanks. This results in major autonomy for vehicles using it. A LNG tank can travel from between 800 and 1,500 kilometres, distances that are ideal for any freight route. It therefore comes as no surprise that the acronym LNG is already widely used in news from truck manufacturers.


Why dieselblend ?

  • Costs reduction!: Gas is cheaper. The more you drive the more you 


  • Reduction of certain emissions by using alternative fuels.

  • Contributes to “green” image of your company

  • Low system costs compared to dedicated engines

  • Reliable: Thousands of systems out in the field

  • Closely matches diesel power, torque and efficiency

  • Not necessary to convert a diesel engine into an otto-engine [mono 


  • Use existing fleet of vehicles

  • No downtime when system fails: ability to switch back to full diesel




Dieselblend is The Dual Fuel system based on the vapor injection of CNG into as a secondary fuel into and existing diesel engine.
-The quantity of diesel injected is reduced, and secondary fuel is injected to make up for the reduced amount of diesel.
-The Prins computer calculates the amount of injected CNG depending on engine load and speed.
-CNG is injected into the intake manifold.
-The amount of injected gas mixes with the intake air.
-The diesel will ignite because of the high compression end pressure in the cylinder and will ignite the gas/air mixture.
