MWM Gas Engines

MWM Gas Engines – A Tradition of Innovation

MWM gas engines are built on a tradition of innovation for 150 years. Founded in 1871, the visionary and automotive pioneer Carl Benz accelerated a new era of gaseous fuelled engines.

Through cutting-edge technology and innovation, MWM has become one of the leading and world renowned in the field of gas engine generator technology and is owned by Caterpillar Inc.

The MWM range of gas engines are manufactured in Mannheim, Germany, and are designed for maximum electrical and thermal efficiency, low operating and service costs, and high reliability and availability. Thus, they achieve efficiencies of over 90%.

Internal workings of the MWM gas engine

A reciprocating engine (also known as a piston engine) is a machine with reciprocating pistons. The gas engine converts thermal energy from the combustion of air and fuel into mechanical work, in this case a crankshaft.

Mechanics of the engine is to move a crankshaft connected to a piston cylinder mechanism by creating large pressure inside the engine’s cylinders.

MWM Engines are spark ignited and operated in a 4-Stroke process:

  • Intake Stroke
  • Compression Stroke
  • Power Stroke
  • Exhaust Stroke

The MWM engine is connected to an electrical generator (Alternator) by a drive coupling to produce electricity.

The engine generator is connected to an electrical circuit breaker so the engine can be connected to the site electrical circuit via an electrical cable. The circuit breaker will synchronise the gas engine to the mains so it can operate in parallel to the existing grid supply.

Heat emitted from the process can either be recovered within a Combined Heat and Power (CHP) configuration which will increase plant efficiency or dissipated to atmosphere via dump radiators.

Finally, the generator is controlled by a sophisticated control panel management system allowing engineers to communicate, analyse and control the plant to ensure optimal performance of the generator.

Power Production

MWM gas engines can be configured to produce a multitude of power scenarios as per the below:

A typical power plant is configured for continuous generation operating 8,000 per year, however, MWM gas engines can operate as flexible Peaking Plants to balance the fluctuating power demand within the local electricity network. MWM gas engines are also suited to produce electricity in parallel with the local electricity grid, operate in Island Mode configuration and Black Start operation.
