Development of the new MAN B and W 32/40 dual fuel engine
- MAN B and W Diesel AG, Augsburg (Germany)
Based on the tried and proven 32/40 diesel engine MAN B and W Diesel AG has developed a dual fuel gas engine covering a rate from 2.4 to 7.2 MW for stationary application in cogeneration and power stations. This paper reports the salient points of the 32/40 DG development project from the concept phase through to prototype testing. To reach the targets a dual fuel prechamber combustion system was developed using an externally arranged, cylinder individual gas admission for the main combustion chamber and a pilot fuel injection to the prechamber. Due to the high thermal and mechanical load sustaining capability of the strong-built heavy fuel diesel engine, bmep (19.9 bar) and efficiency (42.6%) in excess of the targets were achieved with a more than satisfactory life of components. Moreover, the NO{sub x} limit of 500 mg/m{sup 3} as specified in the German TA Luft was successfully met.
