AN Engines releases a new biogas and natural gas engine designed for stationary applications. Based on the MAN E3262 (25.8 L), the MAN E3872 is a 29.6 L 12-cylinder four-stroke engine with spark ignition. The new engine produces 735 kW at 1,500 rpm. Length/width/height of the engine is 1760 x 1245 x 1410 mm and it has a dry weight of 2160 kg. While the new engine uses the same crankcase as the E3262 (in production since 2010), the bore has been increased to 138 mm (+6 mm) and the stroke has increased to 165 mm (+7 mm).
Some unique features have been incorporated in the engine to achieve this power output, says MAN. These include the single turbo concept, which is said to have had a significant impact on engine efficiency through fine-tuning the inlet and outlet guide units (diffuser and nozzle ring).
