An electric drive for a motor vehicle, in particular a fan drive, comprising an electric motor that includes a rotor which is mounted on a motor shaft so as to be able to rotate about a stationary stator as well as a driving part which is coupled to the rotor, and at least one electroconductive cover part for influencing and/or blocking interfering electromagnetic fields generated during operation of the electric motor.

Disclosed is a cooling system comprising: a first cooling circuit with a first coolant pump; a second cooling circuit with a second coolant pump; an expansion tank provided with an expansion chamber for accumulation of coolant, wherein the expansion chamber is connected to the second cooling circuit to allow the expansion chamber to receive coolant from the second cooling circuit; and a deaeration device arranged in the first cooling circuit for separation of air bubbles from the coolant circulating therein. The deaeration device is located at a lower position than the expansion tank and connected to said expansion chamber via a static line to allow air bubbles separated from the coolant in the deaeration device to migrate upwards in the static line towards the expansion chamber.

A cooling system includes a coolant tank, a coolant sensor assembly, and a controller. The coolant sensor assembly includes a sensor package having a first end and a second end, the sensor package including a partially transparent or semi-transparent sight glass housing a coolant level sensor and configured to receive a flow of coolant therethrough. The coolant sensor assembly also includes a first valve coupled between the first end of the sensor package and a coolant tank, a second valve coupled between the second end of the sensor package and the coolant tank, and a third valve coupled in flow communication with the second end of the sensor package. The controller is configured to execute one more diagnostic self-tests for the coolant sensor assembly and the cooling system.

A mid-mounted radiator in a motor vehicle has at least one outgoing air guide attached laterally on the left and right of the radiator. In vehicles with a relatively low cooling requirement, the lateral outgoing air guides are removed and the openings are closed by a cover.

A first coolant flow passage (31, 32) is provided to extend in a longitudinal direction of a cylinder head (101). In at least one of cross sections perpendicular to the longitudinal direction, the first coolant flow passage (31, 32) is located between a flat plane (S1) including central axes of a plurality of combustion chambers (4) and parallel to the longitudinal direction and a central line plane (S2) including central lines of a plurality of intake ports (2). In at least one of cross sections perpendicular to the longitudinal direction, at least a portion (20c) of a second coolant flow passage is located between a cylinder block mating surface (la) of the cylinder head (101) and the intake port central line plane (S2). A coolant at a temperature lower than that of a coolant flowing in the second coolant flow passage (20c) flows in the first coolant flow passage (31, 32).

The present disclosure relates to a system for controlling an air flow rate into a vehicle engine room. The system includes: an air intake port receiving an exterior air at a front portion of the vehicle and supplying the air into the engine room; air ducts formed at both sides of the air intake port and introduce the exterior air into a wheel side in order to improve aerodynamic characteristic; a control valve configured to selectively convey the air flowed in the air intake port into the air ducts; a radiator disposed between the air intake port and the engine room; and a control portion configured to control the control valve based on an operating state of vehicle. The air ducts are selectively communicated with the air intake port and disposed at upstream of the radiator.

A degas bottle for a motor vehicle coolant system is provided. The degas bottle has a body defining an enclosed cavity bounded by an upper wall, a lower wall and a side wall extending between said upper and lower walls. An inlet extends into an upper region of the cavity proximate the upper wall and an outlet extending outwardly from a lower region of the cavity proximate the lower wall. An interior wall is disposed in the enclosed cavity. The interior wall extends from the upper wall toward the lower wall to a free end spaced from the lower wall. The interior wall has a vent opening proximate the upper wall and extends to the side wall on opposite sides of the inlet. A baffle is disposed between the interior wall and the inlet. The baffle extends from one of the upper wall or the lower wall to a free end spaced from the other of the upper wall or the lower wall.

A cooling apparatus of a vehicle driving system for driving a vehicle according to the invention activates a heat pump to cool a hybrid system by cooling medium and flows an engine cooling water in an engine water circulation passage through a condenser to cool the cooling medium by the engine cooling water at the condenser when an engine water circulation condition is satisfied. The engine water circulation condition is a condition that a heat pump activation condition is satisfied, and an engine cooling condition is not satisfied. The heat pump activation condition is a condition that a process of cooling the hybrid system by the cooling medium of the heat pump is requested. The engine cooling condition is a condition that a process of cooling an internal combustion engine by the engine cooling water is requested.

Disclosed are an apparatus and method for controlling an oil pump for a vehicle which may control the speed of the oil pump. The apparatus includes a controller configured to control the speed of the oil pump based on the temperature information of a motor and oil and the speed and torque information of the motor, and, when the vehicle is being driven, the controller confirms whether or not a motor or oil temperature is higher than or equal to a first set temperature, controls the speed of the oil pump to a maximum speed value when the motor or oil temperature is higher than or equal to the first set temperature, and calculates a control speed value and controls the speed of the oil pump to the calculated control speed value when the motor or oil temperature is lower than the first set temperature.

A thermostatic valve includes a housing having a fluid inlet, a first outlet and a second outlet, a flap that is movable between a closed position, in which the flap closes the first outlet, and an open position, in which the flap opens the first outlet. The valve also includes a thermostatic actuator with an actuating rod connected to the flap and a capsule containing a thermally expanding material, and a heating element. The capsule has an internal portion, which extends inside the housing so as to be immersed in the fluid flowing between the inlet and the second outlet of the housing, and an external portion, which extends outside the housing. The heating element is arranged outside the housing and outside the capsule in order to heat the external portion.
