摘要:
A method and a device are described for starting an internal combustion engine of a hybrid drive train, having an internal combustion engine and at least one additional machine, in particular an electric machine, a separating clutch, which is situated between the internal combustion engine and the additional machine, and a crankshaft angle sensor for detecting the instantaneous crankshaft angle of the internal combustion engine being provided. Arrangements are provided to perform the following operations to start the internal combustion engine when a high-voltage battery is essentially discharged, including a) the separating clutch is or has already been disengaged, b) the additional machine is accelerated, c) after conclusion of the acceleration operation of the additional machine, the separating clutch is engaged, so that the internal combustion engine is also accelerated, d) as soon as the crankshaft angle sensor system supplies a favorable crankshaft angle, the internal combustion engine is started by direct start.

The invention relates to a method to regulate and/or calibrate a mixing valve, in particular in a cooling circuit of an internal combustion engine, with which a volume flow can be separated into two partial flows as a function of controlled quantity, whereby the separating ratio of the mixing valve is determined by comparing a target quantity with an actual measured quantity. It is planned that a correction value that is computed during operation is taken into consideration in calculating the separating ratio or mixing ratio (MR). In addition, the invention relates to a corresponding regulating device to regulate and/or calibrate a mixing valve. In this case, it is planned that a correction value that is computed during operation can be taken into consideration in calculating the separating ratio.
摘要:
A cooling circuit for an internal combustion engine includes a first coolant circuit and a second coolant circuit, the cooling circuit being able to be operated by a distributor so that the internal combustion engine reaches its operating temperature as quickly as possible, and a heat exchanger used to heat the vehicle interior is operational as quickly as possible. The return channel from the second coolant circuit is connectable to either the return channel or the flow channel of the first coolant circuit.

An electric machine, particularly a generator for motor vehicles, includes a housing and a casing enclosing the housing concentrically, the casing, together with the housing, bounding an annular space that is sealed in a fluid-tight manner and is connected to a coolant outflow and a coolant inflow. To achieve a uniform circumflow of the housing with sufficient cooling capacity, even given low volumetric flow of the coolant, a plurality of axial guide bars are arranged in the annular space, so that the coolant restrictedly flows in an axially wide-strip manner through the annular space within space segments arranged in a row in the circumferential direction, with an opposing flow direction in successive space segments.
