In an automotive drive, at least one dynamic characteristic of a bearing by which the automotive drive is supported on a beam is selectively influenced during operation of the automotive drive (active bearing). It is provided that a change in an instantaneous operating variable of the automotive drive is determined from a change in a state variable of the active bearing that influences its dynamic characteristic.

摘要:
A method and a device for starting an engine system, especially of a vehicle, which make possible a start of the engine system that is as quick and comfortable as possible. In this context, it is tested for a start request whether a starter-free starting method leads to a successful start of the engine system. For the case in which the test result is negative, the engine system is started automatically using a starter.

A method for restarting an internal combustion engine with the aid of direct start and cylinder deactivation, a control unit, and such an internal combustion engine are provided, it being possible to switch between a cylinder deactivation mode, in which at least one cylinder of the internal combustion engine is deactivated, and a full count mode, and the internal combustion engine being operatable in an automatic start-stop strategy having subsequent direct start. The method includes an automatic stop, the cylinders which participate in the subsequent direct start are operated without combustion in the cylinder deactivation mode during the previous driving operation.
摘要:
A method for operating an internal combustion engine by introducing air, in which the air is conducted into the induction region of the internal combustion engine following shutoff of the internal combustion engine. If necessary, the intake valves and the exhaust valves of at least one cylinder are moved into a position in which at least one intake valve and one exhaust valve of a combustion chamber of the internal combustion engine are open simultaneously. The method may be used in for an internal combustion engine having an electric turbocharger for the introduction of air.

The invention relates to a heating and/or cooling system (2) for a motor vehicle with a combustion engine (4) and a catalytic converter (8) arranged in the exhaust gas path (6) of the combustion engine (4), comprising a burner (10) attached before the catalytic converter (8) to the exhaust gas path (6) as well as a heat exchanger (12) for transmitting heat generated in the burner (10) to a heating and/or cooling circuit (28) of the motor vehicle. It is proposed that the heat exchanger (12) be arranged behind the catalytic converter (8) in the exhaust gas path (6) of the combustion engine (4) and can be acted upon through the catalytic converter (8) with hot combustion gases from the burner (10).

An internal combustion has an exhaust gas line, an exhaust gas heat exchanger through which exhaust gas withdrawn through the exhaust gas line passes so as to take heat energy, a heating heat exchanger to which the withdrawn heat energy is made available and which is connected to a cooling fluid circuit of the internal combustion engine, an exhaust gas turbocharger provided with a turbine housing and a turbine wheel rotatable in the latter, the exhaust gas turbocharger being arranged in the exhaust gas line, the exhaust gas heat exchanger being connected heat conductively with the turbine housing of the exhaust gas turbocharger for withdrawing of heat from the exhaust gas which passes through the turbine wheel.
摘要:
The invention relates to a method for combustion misfire detection and cylinder equalization in a multi-cylinder internal combustion engine having knock control. In the method, rough-running values are individually determined for each cylinder by measuring segment times with each crankshaft rotation. The segment times include the times corresponding to the piston movement of each cylinder to be measured in which the crankshaft passes through a corresponding circular-segment angular region. Thereafter, the determined rough-running values are compared to a threshold value in a desired value comparison and, on the basis of the deviation between the determined rough-running values and the desired value, cylinder-individual equalization factors (that is, correction factors) are computed in an evaluation unit for the change of injection times or ignition time points of the individual cylinders. It is provided that the computed equalization factors (GL1) for the change of injection times or the ignition time points or the charge serve as the basis for the determination of a rough-running increase value (LUTcorrected) effected by the change and that, with the determined rough-running increase value (LUTcorrected), a computation of a corrected rough-running value (dLUT) takes place. The corrected rough-running value (dLUT) is utilized for the computation of the final equalization factor (GL2) for influencing injection times or ignition time points or the charge.
