摘要:
In a method and device for controlling an internal combustion engine having an exhaust treatment system, a quantity characterizing the status of the exhaust treatment system is determined on the basis of at least one operating parameter of the internal combustion engine.
摘要:
Described is a method for controlling a temperature downstream of a catalyst in the exhaust tract of an internal combustion engine including a first control loop in which a first control variable is calculated from a first deviation that is calculated from a first actual value and a first setpoint value and influences an intra-engine heat generation. In the process, the first actual value is determined as a measure of a temperature downstream of the catalyst. The method features a second control loop in which at least one second control variable is calculated from a second deviation that is calculated from a second actual value and a second setpoint value; a temperature upstream of the catalyst being determined as the second actual value. Also described is a controller which controls the sequence of such a method.
摘要:
A method and a device is described for controlling an internal combustion engine using fuel metering. The fuel metering is divisible into at least a first partial injection and a second partial injection. In the second partial injection, a fuel quantity variable, characterizing the fuel quantity injected in the second partial injection, is corrected on the basis of at least one pressure variable, characterizing the fuel pressure, as well as of the fuel quantity variable and at least one further variable.
