Mercedes-Benz M104 қозғалтқышы: тарихы мен модификациялары

The Mercedes Benz M104 is a automobile straight six engine produced from 1988 through 1999. It has a double overhead cam design with 4 valves per cylinder, and used a crossflow cylinder head. It replaced the M103 and was replaced by the M112 V6 starting in 1997. The bore spacing on all M104 engines is the same as M103 engines.

As Mercedes needed a compact 6 cylinder for their Vito, they agreed with Volkswagen to use their VR6 engine, which they then designated M104.900. An agreement was reached and the engines were sold semi completed to Mercedes Benz. This version is unrelated to other engines designated M104. Only the engine cover and aircleaner housing is by Mercedes Benz.

There were 3.6 L conversions done to both the M103 and M104 by Brabus, among others. AMG developed a M104 that was used in the W202 C36 AMG (W202) from M104.941, the W124 E36 AMG (W124) from M104.992, the E36 AMG (W210), and the G36 AMG (W463) vehicles. The AMG 3.6 M104 was rated at at 5,750 rpm and of torque at 4,000 rpm using the HFM engine management system. Bore and stroke is with a compression ratio of 10.5. AMG later conceded that since the engine was hand modified, power outputs could vary slightly from
The boost in displacement was obtained by boring the 2.8 litre M104 block by and using a highly modified version of the crankshaft from the 3.5L OM603 to increase throw by ; this necessitated the use of new forged pistons with shorter skirts. A larger intake crossover pipe, free flowing exhaust, a unique intake camshaft, minor changes to the cylinder head, and modifications to the HFM fuel computer also contribute to the increase in power. Ssangyong (South Korean brand) made a 3.6 litre variant of M104 inline six engine based on the 2.8 litre model, producing or on earlier versions, for its Chairman model, a full size luxury sedan. Chinese car Roewe R95L which based on SsangYong Chairman also uses 3.6 litre version of M104 engine. Last versions of German sports car Isdera Spyder 036i after 1990 also uses 3.6 litre AMG variant of M104, producing 268 (200 kW; 272 PS) or 282 hp (210 kW; 286 PS).

Turbocharger kits were offered for both the M103 and M104 engines by Turbo Technics, Mosselman, Lotec, MAD Modify, Turbobandit and other tuners. These conversions typically raised engine output to between , depend on Boost Target. During the 1990s UK customers were able to buy new vehicles equipped with a Turbo Technics conversion directly from Mercedes dealer Hughes of Beaconsfield (limited run of 75 conversions). Today turbocharger kits for M103 M104 engines are available from later tuners in Europe and Asia.
