  • Patent number: 11035319
    Abstract: The present disclosure relates to an internal combustion engine for a motor vehicle. The internal combustion engine has a cylinder head, a crankcase and a cylinder head gasket. The cylinder head, the cylinder head gasket and the crankcase form a sealing region for sealing at least one combustion chamber. A first recess is arranged within the sealing region and at a distance from the at least one combustion chamber. A first leakage gas passage extends from the first recess to a first surface exposed to the environment of the internal combustion engine or to a ventilation passage of the internal combustion engine.
    Type: Grant
    Filed: February 9, 2018
    Date of Patent: June 15, 2021
    Assignee: MAN Truck & Bus AG
    Inventors: Armin Berner, Thomas Leitel, Walter Schibalsky
  • Patent number: 10774663
    Abstract: A turbocharger assembly for an internal combustion engine, in particular of a commercial vehicle, has a turbocharger with a turbine housing. The turbocharger assembly additionally has an exhaust-gas pipe. The exhaust-gas pipe is arranged downstream of the turbine housing. The exhaust-gas pipe has a diffusor region and an exhaust-gas manifold region.

  • Patent number: 8161936
    Abstract: An internal combustion engine includes an exhaust valve for removing exhaust gas from a combustion chamber and an engine braking device with a hydraulic valve control unit by which the exhaust valve can be held in an intermediate open position when the engine braking device is actuated. A hydraulic valve lash compensation mechanism for the exhaust valve and a control channel formed between the hydraulic valve control unit and the valve lash compensation mechanism for feeding oil to the hydraulic valve control unit that can be closed by a closure element to compensate for the valve lash of the exhaust valve. A counter-holder is constructed as a piston-cylinder unit. The counter-holder forms a variable stop for a valve bridge cooperating with the valve lash compensation mechanism.
