WHAT IS THE DUAL FUEL TECHNOLOGY?
The Dual Fuel technology is based on the concept that inserting additional energy into the combustion chamber of Diesel Engines in the form of natural gas allows the engine to use less diesel to produce the same power. Typically, upto 70 percent of the diesel fuel normally used can be safely displayed with natural gas.
HOW DOES IT WORK?
Natural gas is delivered to the combustion chamber of the engine using the existing air intake system of the DG sets. Hence there is no modification done to the engine or its firing/ignition system or the alternator.
The proprietary Air-Gas Mixer (AGM) is installed just downstream of the stock air filter where it dictates the air-to-gas ratio in conjunction with the Fuel Control Valve (FCV). The mixer uses the Venturi effect to draw gas into the engine. The fuel control valve has a 10-20 millisecond reaction time, allowing immediate throttle adjustment in response to changes in engine load. The fuel control valve utilizes internal software with fault detection and position control and is controlled by the Programmable Logic Control (PLC). Each kit is custom fit and commissioned for your specific engine and application.

Frequently Asked Questions
What does 'Dual Fuel' mean?
Dual Fuel means simultaneous combustion of 2 fuels. In the case of a generator set it is Natural gas and Diesel used in conjunction to run the engine. After the conversion the engine is able to operate on a mixute of diesel and natural gas with up to maximum 70% of natural gas usage.
Do I need to modify my engine to operate on the 'Dual Fuel' system?
No. The Dual Fuel diesel to gas conversion technology has been designed as a retrofit technology. The plug and play model allows for no modification on the engine design or any critical engine parameter. The only modification that is made is that our Air Mixer is installed before the turbocharger. The Air Mixer is then connected to the gas train and the fuel control valve.
What are the economic benefits of converting from diesel to gas?
In the Indian market there is a significant price differential between the cost of diesel and the cost of natural gas. (~50%) Rising diesel prices and access to cheaper natural gas (PNG) has made the Dual Fuel solution more economically viable. Our solution reduces operational fuel expenses by 35%. In addition to the cost savings on the fuel, you would be saving money on engine maintenance and extended runtime (upto 3.4 times longer).
Will the Dual Fuel solution change the durability of my engine?
Operation on a Dual Fuel system has no negative impacts on the durability of an engine. This is because engine thermal loads are equivalent to those run solely on diesel and there is no excess wear of combustion chamber componnents such as pistons, rings, valves, injectors. Installation of thermocouples ensure that operational temperatures always remain within OEM limits. Many users of this technology has reported positive effects on the durability because of the extended oil change intervals and extended time between overhauls.
How will the Dual Fuel solution impact efficiency of the engine?
This technology replaces the diesel fuel with an equivalent amounts of natural gas. This results in the same net fuel that is burnt vs load as would be the case on 100% diesel run generator. For each litre of diesel fuel displaced there is a corresponding combustion of natural gas. This results in similar engine fuel efficiencies. There is no derating of the engine.
Will this affect my engine warranty?
Most OEM engine warranty programs do not prohibit the use of aftermarket parts or technologies. The OEM policies neither recommend nor endorse aftermarket technologies. The end user might retrofit their assets to make them more energy efficient. AMC will continue as usual post retrofit of the engine.
Is Dual Fuel Technology approved by the government?
Yes. The governement in multiple seperate notifications have recommended the retrofit of Diesel Generators to run on partial gas systems. The reason is that PNG is a much cleaner fuel. Dual Fuel Engines not only reduce the PM particles, but also reduce NOx, SOx and CO2 emssions drastically.
