The OM617 naturally aspirated engine is essentially an OM616 with an extra cylinder; it debuted in 1974 with the W115 (240 3.0d) chassis. Bore and stroke was 91 mm × 92.4 mm (3.58 in × 3.64 in). It was originally 80 PS (59 kW; 79 hp). Bosch MW inline injection pumps were used, which had flyweight governors and vacuum shutoff. Previous engines had used pneumatic governors, and "gorilla knob" to start and shut off the engine. The North American engines had ADA device equipped pumps which limited fuel at high altitudes to prevent smoking with less dense air. New engine blocks after the .910 had rear mounted oil filter housings, with a combined full flow and bypass filter element. In August 1978 the precombustion chamber was updated to be similar to the new OM617A design for more swirl and more efficient combustion. The engine capacity was lowered to 3.0 L (2,998 cc) to satisfy engine displacement tax laws in Europe by changing the bore to 90.9 mm (3.58 in). September 1979 saw a new camshaft with greater valve lift let air and exhaust gasses have less resistance. Power output rose to 88 PS (65 kW; 87 hp). Torque remained at 172 N⋅m (127 lb⋅ft) @ 2400 rpm. In November 1980 the MW style injection pump was replaced with the M type for non-North American engines. Engines were equipped with series wired loop type glow plugs up until 1980 when replaced by the much more reliable pencil type plugs (these had been already used in the OM617A since 1978). Vehicles sold to the North American market had exhaust gas recirculation equipment fitted.
