摘要： A method for operating an exhaust gas aftertreatment system, having the following steps: determining a permissible energy input into at least one exhaust gas aftertreatment element of the exhaust gas aftertreatment system; ascertaining a current energy input into the at least one exhaust gas aftertreatment element by ascertaining at least one energy input variable which characterizes the current energy input; and actuating an adjusting device which varies a distribution of an exhaust gas mass flow to the at least one exhaust gas aftertreatment element and a bypass path that runs about the at least one exhaust gas aftertreatment element depending on the permissible energy input and the current energy input.

摘要： A method for carrying out the operation of an internal combustion engine, wherein liquid fuel injection amounts are injected at cylinders of a group of cylinders of the internal combustion engine in the context of injection events, wherein in a first step, a first cylinder of the group with the strongest knocking tendency over a time period is determined, and in a second step an injection correction occurs such that the injection events at the first determined cylinder can be sequentially reduced in their injection duration or injection amount by a first correction value, while the injection duration or injection amount of the injection events at the other cylinders of the group are sequentially increased by a second correction value.

摘要： A diesel engine, in particular a high-power diesel engine, having a variable valve train including an adjusting unit at least for adjusting a cam angle of at least one inlet valve, and a control or regulating unit having at least one operating mode which is for cold starting. The control and/or regulating unit is designed in an operational mode, to adjust the cam angle of the at least one inlet valve to ‘late’ by controlling the adjusting unit.

摘要： The invention relates to a supply system for a medium, in particular for an exhaust-gas purification apparatus for the treatment of exhaust gases of an internal combustion engine, having a storage vessel for the medium, having a dosing device for dosing the medium, and having a provision line which comprises a feed line for the supply of the medium to the dosing device and a return line for returning the medium from the dosing device into the storage vessel. Flow can pass through the dosing device from a feed port to a return port of the dosing device. The provision line comprises an additional fluid connection between the feed line and the return line. The additional fluid connection opens out into the feed line upstream of the feed port of the dosing device and opens out into the return line downstream of the return port of the dosing device.

摘要： A method for operating an internal combustion engine, in particular a gas engine, preferably a lean gas engine, which has at least one cylinder, in order to improve the combustion process, a prechamber is provided for igniting a mixture in a main chamber. A pressure curve is detected by a pressure sensor in the main chamber dependent on a crank angle, and the quantity of supplied fuel is controlled or regulated for each individual cylinder using a fuel metering device and the pressure sensor dependent on a desired output and/or a desired torque and/or a desired rotational speed of the internal combustion engine.

摘要： A method for operating an internal combustion engine having at least one fuel injection valve for introducing fuel into a combustion chamber of the internal combustion engine, the valve being supplied with a specified current intensity in order to adjust a specified flow cross-section of a fuel fluidic connection in the combustion chamber. The maximum specified current intensity during normal operation is equal to a first current intensity and during a release operation is equal to a second, higher current intensity.
