A heating and cooling module for controlling the temperature of at least two coolant circuits, having an evaporator region and a condenser region. The evaporator region has a first flow section through which a first coolant can flow, and the condenser region has a second flow section through which a second coolant can flow. The heating and cooling module has a third flow section through which a refrigerant can flow. The evaporator region and the condenser region are arranged on a common base plate which has the fluid inlets and the fluid outlets for the first coolant, the second coolant, and the refrigerant. The base plate has flow channels, through each of which one of the coolants or the refrigerant can flow. The evaporator region and the condenser region are fluidically connected to the respective fluid inlets and the respective fluid outlets of the base plate via the flow channels.

A heating/cooling module having a condenser region, an evaporator region, and at least one fluid distribution region. The condenser region has a first flow section which can be flowed through by a refrigerant and a second flow section which can be flowed through by a coolant. The evaporator region has a third flow section which can be flowed through by a refrigerant and a fourth flow section which can be flowed through by a coolant. The flow sections are formed by a plurality of flow ducts which are configured between the individual disc elements which form the heating/cooling module. A first fluid inlet and a first fluid outlet are provided, via which the condenser region can be flowed through with a coolant. A second inlet and a second outlet are provided, via which the evaporator region can be flowed through with a coolant.

An electric machine may include a housing, a stator arranged in the housing, and a rotor arranged in the stator and mounted on the housing so as to be rotatable about an axis of rotation. The rotor may have a rotor shaft, which may be led out through a front wall of the housing. The rotor shaft may have, on an outer side of the front wall, a drive element, which serves for transmission of torque between the rotor and a drivetrain. The rotor shaft may be rotatably mounted in a front bearing, which is inserted into the front wall. The front bearing may be, at an inner side of the front wall, sealed off with respect to an interior of the housing by way of a labyrinth seal.

A fuel filter for a fuel supply system of an internal combustion engine may include a filter housing, which may have an untreated-side inlet, a treated-side outlet, and an untreated-side return line. The fuel filter may also include a filter element arranged in the filter housing, and a closure element, which in an operationally ready state of the fuel filter may close off the return line. The fuel filter may include an untreated space and a treated space, and may separate in the filter housing the untreated space communicating with an inlet and the return line from the treated space communicating with the outlet. The fuel filter may further include a pressure sensor configured to measure a pressure build-up in the treated space, wherein the fuel filter may be configured to enable the pressure build-up to reach a predetermined threshold at which the engine may be started.

An intercooler may include an air-outlet tank, a condensate collector for collecting condensate separated off the intercooler, and a condensate line connected to the condensate collector via an entrance and that opens out into the air-outlet tank via an exit. There may be a pressure difference between the entrance and the exit of the condensate line during operation of the intercooler, and said pressure difference may allow differential-pressure-induced discharge of condensate from the condensate collector via the condensate line.
