The engines were derived from the Mercedes-Benz Series 500 engines, which are pro- duced in large quantity for trucks. The rugged, torsionally rigid, gray cast-iron crankcase was designed for minimal weight and accommodates the cylinder lines, crankshaft and central camshaft bearings as well as the injection pumps. It also contains the major passages for lube oil and coolant circulation, and provides attachment points for the engine mounts, as well as for various ancillary and accessory equipment. Together with the respective application-related pistons, the four-valve cylinder heads with central- ly located injection nozzle offer optimum prerequi- sites to tune the combustion for minimum noxious emissions and fuel consumption. The injection system is the same for all applica- tions; it consists of one high-pressure pump for each cylinder. The pumps are controlled by an electromagnetic solenoid valve, supplying the fuel to the central injectors where it is atomized by up to 1,800-bar injection pressures. The engines feature a triple-walled exhaust sys- tem. An outer, water-cooled aluminum casing con- structed from tough (but lightweight) extruded sec- tions with integral coolant passages cools and car- ries the exhaust system along the side of the engines. This is designed to ensure that surface temperatures do not exceed the permissible levels, while providing absolute gas tightness. Inside the cooled outer casing, there is another, high-temper- ature-resistant exhaust pipe. This is designed to ensure that the flow of exhaust gases comes into direct contact with the cooled outer casing as little Series 2000 Technical Specifications Engine model 8,12 and 16 cylinder diesel engines, 4-stroke Vee angle 90 degrees Bore 130 mm Stroke 150 mm Cylinder displacement 1.991 Total engine displacement 11.94 to 31.841 Idle speed 575 rpm Rated speed 1,500 to 2,300 rpm Power per cylinder 34 to 84 kW Total power 270 to 1,343 kW Mean effective pressure 13.6 to 22 bar Average piston speed 7.5 to 11.5 m/sec.
