Definitions
- Modern control systems are available for operating internal combustion engines, which, depending on input variables, adjust the performance of the internal combustion engine by controlling performance parameters of the internal combustion engine.
- a variety of monitoring measures are to be provided which ensure safe operation of the internal combustion engine and the availability of the internal combustion engine.
- DE-A 195 36 038 (US Pat. No. 5,692,472) describes the monitoring of the control of an internal combustion engine on a torque basis. A maximum permissible torque is determined there at least on the basis of the accelerator pedal position. Furthermore, the current torque of the internal combustion engine is calculated depending on the engine speed, ignition angle setting and load (air mass, etc.).
- the maximum permissible value is compared with the calculated current value. Failure response measures will be initiated when the current value exceeds the maximum allowable.
- This monitoring strategy offers reliable and satisfactory monitoring of internal combustion engines. However, it is based on the measured air mass supplied to the internal combustion engine. In the case of internal combustion engines that are operated at least in one operating state with a lean air / fuel mixture, such as, for example, directly injected gasoline engines or diesel engines, the torque determined from the measured air mass does not correspond to the actual values, so that the monitoring strategy described is only conditional here is operational. For example, in gasoline internal combustion engines with direct injection in stratified operation, the detected air mass and the set ignition angle are not sufficient to calculate the current torque.
- DE-Al 196 20 038 Another individual measure is shown in DE-Al 196 20 038. There, to monitor a fuel metering system, a signal from a sensor that detects the exhaust gas composition is checked for deviations from a predeterminable value.
- Torque of the internal combustion engine which is generated directly by the combustion of the gas mixture.
- the torque output by the internal combustion engine is calculated from this, taking into account loss moments and consumer moments. It is particularly advantageous that the accuracy of the monitoring is improved, since it is not the air flowing through the throttle valve that is used as an indicator of the indicated engine torque, but rather the fuel mass injected into the cylinder, which determines the torque in the lean and stoichiometric operating states of these engines Size is.
- FIG. 3 a preferred exemplary embodiment of the solution according to the invention is outlined as a flowchart which represents a program implemented in the microcomputer of the control device.
- the specification of the permissible torque as a function of speed is shown for a preferred application in FIG. 4 using a characteristic curve.
- step 106 operation of the internal combustion engine is initiated in accordance with step 106, in which the air / fuel mixture is stoichiometric, ie the ⁇ value is 1.
- the internal combustion engine is therefore operated in homogeneous operation. Further monitoring then takes place on the basis of the actual moment, which is calculated on the basis of the relative filling, ie the air mass supplied, as shown in the prior art mentioned at the beginning.
- the program is then ended and run through in the next interval.
- step 116 it is checked in step 116 whether there is an exceptional operating state which leads to an unscheduled injection of fuel.
- Such operating areas are, for example, operating areas in which a larger quantity of fuel is injected against the current operating state in order to protect the catalyst or to heat or keep it warm. If such an exceptional operating situation exists, the torque monitoring described below in lean or stratified charge operation is continued in accordance with steps 118 to 124. If there is no such exceptional operating state, the internal combustion engine is in overrun mode. In this operating state, at least at speeds above a limit value, the injection time or the injected fuel mass is zero as a result of the fuel cut-off operating in overrun mode in normal operation.
