The OM 601 by Mercedes-Benz is a four cylinder - diesel engine with indirect injection , the 1983 mid-size model 190 D was introduced. The in- line engine is technically closely related to the five- and six-cylinder derivatives OM 602 and OM 603 , which u. a. were also used in the W124 series (predecessor of today's E-Class).
technology
The engine block is made of gray cast iron, like its predecessor, with dry cylinder liners made of centrifugal cast , and the cylinder head made of light metal . A duplex timing chain drives the series injection pump from Bosch and an overhead camshaft , which two valves per cylinder bucket tappets with hydraulic lash adjuster operated. The mixture is prepared in antechambers with spherical heads, glow plugs and flat pin injection nozzles.
The OM 601 is not only much more compact than its predecessor OM 615, it is also significantly lighter. Compared to the previous series, the engine block has a more modern design, with more stiffening ribs and thinner walls that are pulled down over the center of the crankshaft. The OM 601 is 49 kg lighter than the OM 615 (with oil and water). In addition, it offers higher torque and higher peak performance while at the same time reducing fuel consumption and pollutant emissions.
The OM 602 and OM 603 engines differ from the OM 601 only in the larger number of cylinders. All basic dimensions as well as cylinder bore and stroke are the same (except for the versions with larger displacement). They also have an identical output per liter and almost the same torque curve. All pistons, connecting rods, pre-chambers and injection nozzles are identical.
From the start of series production, the three engines are equipped with a so-called serpentine drive: the auxiliary units (fan, water pump, alternator , steering servo pump and, if necessary, air conditioning ) are driven by a ribbed belt with an automatic tensioning device instead of several V-belts.
Due to the encapsulation remote from the engine, the noise emissions of the vehicles equipped with the new engines are particularly low; less than half as loud as comparable drives.
The thermostat - controlled fuel preheating by means of a coolant-fuel heat exchanger , which all engines in the OM601 to OM603 series have, is also remarkable. As a result, clogging of the fuel filter with solid flocculation from the diesel fuel is almost impossible even in winter conditions.
The OM 601 to 603 engines with the robust Bosch in-line injection pumps (R-ESP) can be operated not only with biodiesel , but also with vegetable oil (such as rapeseed oil ) without major modifications . The start of injection delivery should then be adapted to the more viscous fuel, which ensures reliable operation up to +5 ° C.
history
The OM 601 was presented in 1983 in the 190 D series. From 1984 it was also installed in the 124 series . The larger variants OM 602 and OM 603 were also used here, which powered the 200 D, 250 D and 300 D models and thus replaced the predecessors OM 615, OM 616 and OM 617 .
Initially, all engines in this series were only available as naturally aspirated engines , later variants with turbocharging were added. These turbos had a noticeable feature in the 124 and 201 series cars: the intake air requirement was so great that the normally installed air duct in the engine compartment did not function adequately. A young development engineer suggested using the conspicuous feature of the "gill slits" in the front right fender . Six gill slots were added to the 190 D 2.5 turbo five-cylinder; the larger Mercedes 300 D turbo six-cylinder had five, each in the right front fender in front of the wheel cutout. The smaller engine with turbocharger developed 90 or 93 kW (122 or 126 hp), the large three-liter engine initially 105 kW (143 hp), later 108 kW (147 hp). Later, suction diesel models with gills were also delivered.
For use in vans ( T 1 ) and as an industrial engine, versions with 15% more displacement were available. The six-cylinder OM 603 engine with turbocharging was also installed in the 126 series S-Class cars for the USA . Later it was used with an enlarged displacement (3.5 L) in the 126 series and in the subsequent 140 series.
As part of the "Diesel '89" development program, all engines in the OM 601 to 603 series were modified. Particle emissions have been reduced by around 40 percent by improving the combustion process. As a result, they now work practically smoke-free and meet the strict particulate limit values in the USA even without a soot particle filter . This success was achieved through a newly designed prechamber with inclined injection , which ensures more efficient combustion. In addition, the injection pumps of all naturally aspirated diesel engines were given an altitude correction box to keep emissions low even when operating at high altitude. These modifications also increased the performance slightly. An optionally available oxidation catalytic converter coupled with exhaust gas recirculation further reduced exhaust emissions.
Direct injection OM 602 DE 29 LA
Over time, the engines of this series were modernized and from 1993 successively replaced by the types OM 604, OM 605 and OM 606 with four valves per cylinder, some of which were also available with a turbocharger. The proven pre-chamber injection was retained, with the exception of the E 290 turbodiesel from the 210 series and the T1N (Sprinter). This had a direct injection variant of the OM 602 with an EDC distributor injection pump from Bosch .
The five-cylinder engine type OM 602 DE 29 LA (OM 602.982) with a displacement of 2.9 liters occupies an exceptional position. It was installed in the early years of the E-Class series 210 and in the T1N (Sprinter) with turbocharging and charge air cooling. This was the first Mercedes passenger car diesel with direct injection, but still without a common rail system (CDI) and four-valve technology. Despite pilot injection and the very restrained power rating, the engine had the typical loud noise of a first-generation direct injection engine. To reduce the noise level, much more extensive insulation than before was necessary.
The engine was installed in the E-Class 210 series with 95 kW (129 PS), in the G-Class with 88 kW (120 PS) and in the Sprinter small van with 90 kW (122 PS), as well as in the Unimog U90 (408 ) and UX100 (409).
License construction OM 662
For the SsangYong Motor Company in Korea, another offshoot of this engine was developed for their models Musso, Korando and Rexton, which Ssangyong itself produced under license. It is based on the OM 602 DE 29 LA, but was upgraded to pre-chamber injection and was given the name OM 662. This engine was not used by Mercedes-Benz itself, but it is part of the spare parts program there. The engine was offered with (88 kW) and without a turbocharger (70–72 kW).
Starting in 2004, SsangYong modified the engine on its own: It was reduced to 2696 cm³ (86.2 × 92.4) and converted to four-valve technology including common rail direct injection. The engine now developed 121 kW (165 PS) and has a torque of 340 Nm in a speed range of 1800–3250 rpm.
