An active grille shutter for regulating airflow towards a vehicle heat exchanger. A frame adjacent the heat exchanger has a first mount with bores, a second mount, and an opening between the mounts to allow air to pass through. An end cap secures to the second mount and has bores. Vanes extend across the opening between opposing ends with a receiver at each end. Bearings are provided with couplers extending into and attached to the receivers, and a shafts extending into the bores. A linkage interconnects the bearings at one of the ends such that the vanes rotate concurrently. An actuator attached to the frame adjacent the first mount is coupled to one of the end cap bearings and rotation imparts rotation to the vanes by the linkage to concurrently rotate the vanes within the opening to regulate airflow through the opening towards the heat exchanger.

The present disclosure relates to a device for influencing an air flow within an engine compartment of a motor vehicle. The device comprises an adjusting means for adjusting the device between two end positions. The device is allocated to a part region of the engine compartment so that in one of the end positions, an air flow that is provided in the engine compartment is in part or entirely either guided into the part region or guided away from the part region.

An air flap system for controlling air ingress into a motor vehicle has at least one air flap, which can be pivoted between an open position and a closed position, and an actuator, which is coupled to the air flap, such that the actuator is suitable for effecting the pivoting of the air flap. The actuator is arranged off-center in a central region with respect to one extent of the air flap system along a transverse axis of the vehicle. The central region is one of at least three regions which are arranged adjoining one another along the extent, the central region being arranged centrally with respect to the extent.

A grille shutter actuation system for a vehicle includes a grille shutter, a linear actuator having a cylinder with first and second orifices and a piston. The piston is connected to the grille shutter for moving same. Fluid is pumped into one of the orifices through first or second hoses for moving the piston. A bi-directional motor is connected to the pump, and a controller controls a direction of rotation of a motor shaft in response to an input. A control module provides the input to the controller which determines whether fluid is pumped into the first or second orifice dependent upon the direction of rotation of the shaft. The input is determined by the control module based on information from the controller and/or a sensor associated with the grille shutter. The pump and motor may be remotely mounted within an engine compartment, for example, a distance from the linear actuator(s).

Methods and systems are provided for adjusting a grille shutter opening based on an estimated amount of fuel in oil dilution. In one example, a method may include adjusting a grille shutter opening to a closed position in response to an oil dilution amount above a threshold, the position determined based on the oil dilution amount in addition to each of engine coolant temperature and acceleration/deceleration.

A waste heat accumulator/distributor system for use in a vehicle. The system includes an engine coolant loop directing engine coolant through a power plant, a powertrain electronics coolant loop directing electronics coolant through a powertrain electronics system; and a transmission fluid loop directing transmission fluid through a transmission. The system includes a multi-fluid heat exchanger including an engine coolant inlet receiving the engine coolant from the engine coolant loop, an electronics coolant inlet receiving the electronics coolant from the powertrain electronic coolant loop, and a transmission fluid inlet receiving the transmission fluid from the transmission fluid loop; a first valve controllable to cause engine coolant to flow into the engine coolant inlet or to bypass the engine coolant inlet; and a second valve controllable to cause electronics coolant to flow into the electronics coolant inlet or to bypass the electronics coolant inlet.

A heat radiation amount from the cooling water in the radiator is adjusted so that the temperature of the cooling water is less than a prescribed temperature that is a temperature higher than the threshold value if a load exerted on the internal combustion engine is not less than a predetermined load, while the heat radiation amount from the cooling water in the radiator is adjusted so that the heat radiation amount from the cooling water in the radiator is increased if the load exerted on the internal combustion engine is less than the predetermined load as compared with if the load exerted on the internal combustion engine is not less than the predetermined load.
