  • Internal combustion engine
    Patent number: 5669346
    Abstract: In an engine block comprising a casting including side walls extending along a row of cylinders and front and rear walls extending between the side walls with top flanges for mounting a cylinderhead and bottom flanges for mounting an oil pan, the side walls have sections extending forwardly beyond the front wall to define therebetween a timing drive chamber.
    Type: Grant

    Assignee: Mercedes-Benz AG
    Inventors: Johannes Leweux, Hubert Schnupke, Albert Pietsch
  • Tensioning device for a chain of an internal combustion engine
    Patent number: 5662540
    Abstract: In a device for tensioning a chain of an internal combustion engine, especially an oil-pump chain, with a tensioning arm preloaded by a spring device and supported in a point of support, the tensioning arm is supported at one of the support points of a chain guide. The chain guide guides a further chain, particularly the timing chain of the internal combustion engine.

  • Bearing bridge construction for the crankshaft mounting of a combustion engine
    Patent number: 5054442
    Abstract: The invention relates to a bearing bridge connecting the main bearing seats of a reciprocating-piston combustion engine in the longitudinal direction of the crankshaft. To reduce the power loss caused by the oil flowing back into the crank case space striking the rotating drive parts, and the oil ageing rate, it is proposed to provide the bearing bridge between the main bearing seats with a shape which screens off the rotating drive parts of the combustion engine with respect to the crank case space.

  • Arrangement for supporting a crankshaft
    Patent number: 4922870
    Abstract: In a multi-cylinder internal-combustion engine, bearing shell and bearing cap of the bearings for the crankshaft are decoupled from the side walls of the cylinder block which form the crankcase. The bearing shells communicate with the cylinder block directly through column elements. The resilience of the column elements relieves the cylinder block of any transverse flexure by crankshaft forces and reduces the generation of noise.
