MTU Onsite Energy introduces further developed Series 4000
natural-gas engine
Efficiency increased to 44.3 percent
Electrical output of gas engine systems increased by up to 30%
March 17, 2014 + + + MTU Onsite Energy, a
Rolls-Royce Power Systems AG brand, is introducing the further developed
Series 4000 natural gas engine in April 2014. The new-generation engines
achieve up to 44.3% electrical efficiency thanks to optimized combustion
and improved mixture formation. Furthermore, their electrical output has
been increased by up to 30%. These engines are being installed in MTU
Onsite Energy decentralized energy systems. The systems for generating
heat and power have an electrical output of 1,110 to 2,530 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.
This further developed Series 4000 engine
generation allows higher brake mean effective pressures and therefore
ensures maximum efficiency. The modified MTU-proprietary, electronically
optimized controller platform allows an improved control quality and
simplifies the application. A modified single-stage charging system allows
higher pressure ratios with two-stage mixture cooling. These new
developments allow the natural gas to be used even more efficiently for
generating heat and power. The further developed engines retain their
hallmark reliability and durability despite the increase in output and
efficiency. By way of example, the engines can still be operated for
around 63,000 hours before requiring a major overhaul.
The MTU
Onsite Energy systems are used as gensets 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.
A genset featuring the further developed
natural gas engine will be on show on Stand J50 in Hall 27 at Hannover
Messe, the Hanover industrial trade fair from April 7 till 11, 2014.
