  • Method of operating an internal combustion engine
    Patent number: 10161320
    Abstract: A method of operating an internal combustion engine, in particular a gas engine, comprising at least one combustion chamber to which a charge air is fed with a variable charge pressure and/or a variable amount of charge air, wherein a cylinder pressure value is ascertained from at least one measurement value of a sensor arranged in the at least one combustion chamber, wherein the cylinder pressure value is regulated by altering the charge pressure and/or by altering the amount of charge air as a setting value or values to a cylinder pressure target value, wherein the cylinder pressure target value is selected in dependence on a power of the internal combustion engine.
    Type: Grant

  • Internal combustion engine
    Patent number: 8136513
    Abstract: The invention relates to a method for operating an internal combustion engine, wherein air is inducted and then compressed. Before introduction into a combustion chamber of the internal combustion engine, the air humidity of the inducted air is determined and temperature of the compressed air introduced into the combustion chamber is altered depending on the air humidity of the inducted air.
