What is Dual Fuel Kit: -

  • Dual Fuelling is simultaneous combustion Methane rich gas (most often Natural gas) with Diesel as fuel.
  • After conversion, the engine can continue to operate with only Diesel also. However, a ‘Gas only’ operation is not possible.
  • During Dual Fuel operation, a reduced quantity of diesel fuel acts as the ignition source for the air-gas mixture.
  • The Methane rich gas mix replaces significant proportion of Diesel to produce equivalent heat energy during combustion in the cylinder.

Benefits of dual fuel engines: -

  • Flexibility - Can be operated on only diesel in case of non-availability of gas. In case of any DF fault, only DF controller shut off the gas supply and genset will run on diesel only mode.
  • Field conversion is possible from diesel to dual fuel.
  • Reduce the cost of generation - Dual fuel engines deliver financial savings through reduced diesel fuel consumption. Gas is Cheaper than Diesel.
  • Environment protection compared to Diesel engine - Due to clean burning characteristics of Natural Gas, exhaust is cleaner.
  • No power loses or deration - Higher specific power output compared to gas engine and same as diesel engine.
  • Nationwide service network.
  • Low capital cost compared to gas engine
  • Note :- At any time, Dual fuel converted engine can’t be operated with Gas exclusively (100%)

Dual Fuel Working Principle:-

  • The Natural gas used for Dual Fuelling is sourced from either piped gas or from local storage.
  • It is injected into the combustion air stream via a Gas Train consisting of a gas filter, gas pressure regulators and a solenoid valve.
  • A flow control valve at the end of the train controls the proportion of the gas injected through a gas mixture unit.
  • The gas train is designed to accept input gas at low pressure and deliver it to the engine at a slightly negative pressure.
  • In dual fuel mode, natural gas is introduced into the engine’s intake system.
  • The air-to-natural gas mixture is then drawn into the cylinder, just as it would be in a spark-ignited engine, but with a leaner air-to-fuel ratio.
  • Near the end of the compression stroke, diesel fuel is injected and ignites, causing the natural gas to burn.
  • A dual fuel engine can operate on 100 percent diesel fuel or the substitution mixture of diesel and natural gas
  • It delivers the same power density, torque curve and transient response as the base diesel engine.

Dual Fuel Kit Scope components:-

Gas Train: -

  • Gas filter, Pressure regulator, Gas Pressure Gauge, Zero Pressure regulator, Gas shutoff valve and Gas flow adjusting valve
  • Gas piping from gas train to Gas mixer and Gas mixer unit (depends on number of Turbocharger in engine – same qty as Turbo


  • Dual Fuel System delivers fuel gas to the combustion cylinders via the Gas Train into a special Air-Gas Mixer.
  • The mixer is installed on the engine air inlet before the Turbo charger.
  • Combustion is commenced by Diesel as the ignition source and followed by ignition of the Gas


  • Gas pressure sensor and Boost pressure sensor
  • Exhaust gas temperature sensor/s and Intake manifold temperature sensor
  • Vibration sensor/s

Control Panel

  • Controller continuously monitors critical engine parameters through the operation and transitions.
  • It provides safety to the engine while operating in the Dual-fuel mode.
  • PLC, input / output units
  • HMI and switches / buttons/ wirings etc
  • Remote monitoring system - Optional with 3 months free subscription

Dual Fuel Installation requirements:
