Cover Story Gas Engines

The new gas engine 20V35/44G by MAN Diesel & Turbo SE has a power output of 10.6 MW. The high effective efficiency level of 48.4 % as well as numerous technical innovations allow an environmentally-friendly, economical and reliable engine operation. Key to achieve this is the combustion system, which has been optimised during advanced engineering by means of modern simulation tools and extensive single-cylinder tests.

Gas Engines Become More Important

Gas engines are becoming increasingly important in the field of stationary power plants as well as in marine applications. The main reasons for this are the lower fuel costs in comparison to diesel engines, the lower emissions and the increasing significance of CO2emissions as a cause for climate warming. The price for natural gas will probably be lower than for liquid fuels even over the long term, since the supply rate will increase through the use of unconventional production methods which are now employed, particularly in North...
