Both camshafts are driven by a gear drive which is located at the output side of the engine. The position of this drive gear makes a major contribution to reducing noise emission.
The OM 471 engine is available in four output stages between 310 and 375 kW. Advantages of new 6 > cylinder inline engine: Lower fuel consumption in relation to high output Smooth running characteristics, whereby only four counterweights are required on the crankshaft Excellent application capability for the various emissions standards Implementation of particularly high combustion pressures of up to 230 bar The extremely compact design of the engine is based on the optimized cylinder liner concept in which the overhead seat is located at the bottom in the crankcase > this design measure allows the gap between the cylinders to be reduced considerably.
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> The positive properties of the new engine have been made possible by a variety of new technical developments: The new injection system, the amplified pressure common rail system (APCRS) (1), is the first common rail system to be used in Mercedes > Benz commercial vehicles that minimizes the quantity of fuel required for combustion.
The advantage of this system lies in the fact that the rail and high > pressure lines have a relatively low pressure of 900 bar, and the fuel pressure required for injecting into the injector is generated, which has a particularly positive effect on material loads and therefore on component longevity. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> The completely redesigned engine brake system has an even higher braking power.
The cooled and regulated exhaust gas recirculation (EGR) (9) and the diesel particulate filter (DPF) as well as the modified oil separator of the crankcase ventilation system (7) ensure that tomorrow's emissions regulations can also be met. The regulated coolant pump installed in the oil/coolant module (3), which has already been installed in Actros vehicles, also contributes to fuel economy. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> i With each maintenance and repair work to the engine as well as to the ancillary assemblies and detachable parts comes the danger of property damage caused by soiling and foreign bodies.
The high pressure diesel injection system, the intake system and the oil circuit, in particular, are at risk here. To avoid any damage, when conducting repair work not only the specified special tools must be used along with observance of the WIS repair instructions, but in addition to this special care must be given to cleanliness at the workbay.
