SEMT-PIELSTICK PA 6-280 DIESEL ENGINE

This engine is designed to provide the highest output per cylinder capable of installation on locomotives operating on the standard gage of the International Union of Railways (UIC). Further to extend its applicability, the engine has been designed to operate on the heaviest residual fuels so it can be readily adapted as prime mover for small electric power stations or for propelling ships of moderate tonnage. Simplified maintenance has also been a guiding principle. Cylinders (bore, 280 mm, stroke 290 mm) are arranged in a 60 degree V. In "stage one" of the design, 350 hp/cylinder is obtained at 1050 rpm; in "stage two", 400 hp/cylinder has been obtained at 1100 rpm. Engines in 12, 14, 16, and 18- cylinder versions have been built. Design details are illustrated and discussed. Specific fuel consumption of less than 160 grams/hp/hr has been obtained at 350 hp/cylinder on a 12-cylinder engine. Although the first engines have been in service since 1973, experimental work is continuing at increases in power to 500 hp/cylinder. A merchant-marine version is also under test.
