Dual Fuelling is simultaneous combustion of two fuels. GasTech Dual Fuel solutions comprise of special kits that can be retrofitted on existing high speed diesel engines to allow use of a mixture of 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. The emissions from such engines see an order of improvement. In the current market conditions this also means significant reduction in cost.
