V8 Gas Engine For CHP.: MAN Nutzfahrzeuge

This document summarizes the specifications of the MAN E2848 V8 gas engine, which is designed for continuous power (COP) applications in cogeneration plants. The 8-cylinder engine has a displacement of 14.6 liters and is water cooled and turbocharged. It is compact at 1,210mm long, 1,172mm wide, and 1,340mm tall. The engine operates at 1,500 or 1,800 rpm and achieves high efficiency of up to 90.1% thermal efficiency while meeting emissions standards. It is suited for operating 8,000 hours per year with low fuel and oil consumption and long service life.

V8 gas engine for CHP.

Engineering the Future – since 1758.


MAN Nutzfahrzeuge
Efficient and Clean.
Producers and operators of cogeneration plants have stringent demands.
Robust and compact engines have to work reliably round-the-clock.
Economic operation is important for the lifetime of the complete plant.
Economic means highly efficient use of resources and low running costs
of the plant. Due to continuous development MAN engines always work
highly efficiently, reliably and environmentally-friendly.
