Unveiling The Latest Development

Efficiency, output increased; gen-sets for producing power in decentralized plants, modules in cogeneration power plants

Posted on March 19, 2014

MTU Onsite Energy, a Rolls-Royce Power Systems AG brand, has further developed its Series 4000 natural gas engine.

The company said the engines achieve up to 44.3% electrical efficiency thanks to optimized combustion and improved mixture formation, thus increasing the electrical output by up to 30%.

These engines are being installed in MTU Onsite Energy decentralized energy systems for generating heat and power and have an electrical output of 1110 to 2530 kW and will be available as 8-, 12-, 16- or 20-cylinder variants. The 12- and 16-cylinder variants will be available from April 2014 with the other variants to follow in succession.

MTU Onsite Energy said the newly developed Series 4000 engine generation allows higher brake mean effective pressures and therefore ensures maximum efficiency. The electronically optimized controller platform allows an improved control quality and simplifies the application, the company said. A modified single-stage charging system allows higher pressure ratios with two-stage mixture cooling.

The MTU Onsite Energy systems are used as gen-sets for producing power only in decentralized power plants or as modules in cogeneration power plants which supply both heat and power for residential areas, building complexes or industrial complexes, the company said.
