Benefits of DUAL FUEL

The operation of a dual fuel engine is mainly focused on emission characteristics of engine and specific fuel consumption. 

Dual fuel engines reduce emission  of pollutants (such as COx, NOx, HCs etc.) during exhaust after combustion of fuels and specific fuel consumption. 

Dual fuel engine is operated with a primary fuel and a secondary fuel. Diesel is used as primary fuel and L.P.G., CNG, LNG. or Hydrogen are used as secondary fuel.  These secondary fuels are defined in  Article 2 of DIRECTIVE 2014/94/EU as Alternative Fuels

Secondary fuels are used in gaseous form, so secondary fuel is pre-mixed with the intake air, this mixture is lean and ignition of this charge is accomplished by injection of small amount of primary fuel. In dual fuel operation a small amount of gaseous fuel releases higher energy during combustion. In any engine, the emission characteristic of the engine is very important and emission pollutants in atmosphere is a big issue

LNG, CNG, and LPG have smaller carbon-to-hydrogen ratios. Hence, much less CO2 is emitted to produce the same output with about the same fuel conversion efficiency.

LPG is liquid in normal conditions, but it vaporizes much quicker than the diesel. This practically reduces to zero the PM emissions (apart from those originating from the pilot diesel)

LPG as part of Dual Fuel technology.

Delivering significant economic and environmental benefits to the Vehicle Operator.

The EU Fuel Quality Directive publishes carbon intensities of the current major fuels and notes that LPG has 23% reduced carbon intensity versus diesel 

The introduction of LPG as a dual fuel will significantly reduce Co2 and other emissions.

Replacing up to 30% of the expensive and carbon-intensive primary fuel (diesel) with the less expensive and lower carbon-content secondary fuel, LPG through dual-fuel technology will deliver significant economic and environmental benefits to the Vehicle Operator.
