Powergen Duel Fuel 
Conversion Kit

WHAT IS

Duel Fuel

  • 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.

WHY DUEL FUEL ENGINE

Benefits

  • 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%)

INNOVATION

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

Mixer:-

  • 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

Sensors:-

  • 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
