New Krupp Mak M 32 diesel engine
Krupp MaK presented the long-stroke, medium-speed M 32 engine that covers a power range of 2640 kW to 7680 kW. The M 32 engine is designed for marine and stationary applications. The in-line engines are mainly designed for marine use and have a particularly long stroke for high economy and environmental compatibility. Output is 440 kW/cyl at 600 r/min. Specific fuel consumption during the tests was measured at 180 g/kWh at full load. The V-type engines will be designed with a shorter stroke. The higher speed of 750 r/min results in a higher power density and a better synchronous speed for smaller generators. The power plant rating is set at 480 kW/cyl. A modular design concept is applied for ease of assembly and service. Krupp MaK has developed the VMP system as well as systems for air bypass, exhaust gas blow-off and air blow-off, which can be adapted to suit the requirements of engine operation by means of an engine management system. Special controls to keep the exhaust gas temperature as constant as possible in order to use an SCR system most effectively are under development, as well as control devices for bypass of exhaust gas for reduced emissions. The new M 32 engine with its high bore-to-stroke ratio offers ideal preconditions for a high compression ratio of 16:1 and more. 5 figs., 2 tabs.
