WASTE HEAT UTILISATION WITH FOUR-STROKE DIESEL ENGINES

The Sankey heat flow diagram for the M.A.N.-B & W slow-speed diesel engine L 58/64 indicates a mechanical efficiency of 48%. The residual heat energy can be recovered from the exhaust gas, the turbocharging air and the cylinder cooling water. The paper reviews research at M.A.N. on the development of waste heat utilisation systems in each of these areas. Of particular interest is a concept for a "block heat engine" <BHKW> in which the main engine, electrical generators, cooling systems, heat exchangers, etc. are aggregated in modular form. Using this system, the utilisation efficiency of the primary energy can be increased to over 80%.
