Multi-fuelled gas engines are ideal for many applications

Gas engines are ideal for electric power generation, combined heat and power units and tri-generation applications. With 300-1000 kW outputs, our 4000 Series gas engines are powering customer needs in hotels, hospitals and local community projects.

Our gas engines don’t only run on natural gas. The technology used in our engines means that a variety of gases can be used, many of which are free by-products of a business’s operation. Perkins is keen to hear from customer’s trialing new fuel sources for their Perkins gas engines.

Using gas to power your engines gives you a cleaner and quieter operation than with a diesel engine.

Perkins gas engines are ideal for your applications, particularly for:

  • Power generation
  • Combined heat and power units
  • Tri-generation
  • Quad-generation
Gas engines: The ideal choice for combined heat and power schemes.

With our 4000 Series gas engines you get 300-1000 kW output, powering your needs in hotels, hospitals and in local community projects.  And they run on gases including:

  • Natural gas
  • Biogas - landfill, sewage and anaerobic digester

In many cases, the gas is free, such as with landfills or anaerobic digesters. If it isn’t used to power a gas engine, it would be vented or flared off to atmosphere.

Electric power

Whether for prime electric power generation, running each day, everyday, or for standby generation, running only occasionally, our gas engines give you the necessary reliability for your generation needs.

Your organisation could also benefit from ‘payback’, selling the surplus energy you generate back to the national grid.

Combined heat and power

The cleaner and quieter burning in gas engines compared to diesel equivalents make gas an ideal fuel for combined heat and power (CHP) schemes.

Also known as cogeneration schemes, heat arising from the generation of electricity is not wasted but used to supply space and water heating immediately adjacent to the CHP plant, where clean and quiet operation is desirable.


Gas engines are not only about providing electricity and heat. They can also be used in conjunction with absorption chillers to provide cool water for air conditioning units. The ratio of electricity produced and exhausted heat for the absorption chiller and then the ratio of cooling to heating can be varied to meet the specific site requirements.

With the recommended maintenance, gas engines give you a low cost, proven and reliable option for your tri-generation needs.


Additional applications such as greenhouses and bottling facilities can also benefit from the extra carbon dioxide output from a gas engine – ideally supplied by our gas engines – along with the electricity, heat and cooling.

Plants use carbon dioxide naturally occurring in the atmosphere, along with sunlight, to produce the energy for growth.

In natural circumstances, the carbon dioxide in the atmosphere is 300 parts per million (ppm). The concentration drops as plants use it up and when it reaches 200 ppm, plant growth stops.

Many greenhouses are using the carbon dioxide emissions from gas engines to keep the carbon dioxide inside their greenhouses at an optimum level. To buy it in as a liquefied gas is both expensive and unnecessary if you already have the carbon dioxide coming from your gas engine.

Once the engine’s emission gas has been scrubbed of unwanted carbon monoxide and nitrous oxides it can be piped into the greenhouse.

New sources of gas fuel

Perkins is very keen to hear from customers who would like to run or our engines on newer sources of gases. Some gases are not so high in methane and may contain contaminants, such as tar in wood gas that could clog up an engine. But with the close collaboration with our Perkins distributors we could tailor solutions to suit.

If you are running field trials of a new source to fuel a gas engine we would like to hear from you. We’d like to prove the suitability of new gas sources and help other customers get cost effective solutions with their gas engines.

Global electrical power demand will be 80 percent higher by 2040, with gas becoming a key energy source for EP generation.
