An engine cooling system includes an engine, an intercooler, a radiator fan, a cooling circuit thermally coupled to at least one of the engine and the intercooler and circulating a coolant, and a controller in signal communication with the cooling circuit. The controller is configured to: upon receipt of a request, when the engine is in an off state, activate a quick cooldown mode where the radiator fan and the cooling circuit are operated to circulate and supply the coolant to at least one of the engine and the intercooler to cool vehicle under hood components while the engine is in the off state.

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 work vehicle includes an engine, a post-processing device, and a cooling fan. The engine is mounted on a front portion of a travelling machine body. The post-processing device purifies exhaust gas of the engine. The cooling fan water-cools the engine. The cooling fan is located in front of the engine. The cooling fan, the engine, and the post-processing device are covered with a hood. The hood includes a shield. The shield covers a lower section of the post-processing device and one side of the engine. The shield is a perforated plate including a plurality of holes.

A firewall (11) is provided as a partition between an engine room (25) in which an engine (7) and an exhaust gas post-treatment device (10) are arranged and a pump room (26) in which a hydraulic pump (8) is arranged. A rear surface plate (13) of the firewall (11) is provided with an outflow opening (28) for causing cooling air sucked into the engine room (25) to flow out toward a counterweight (6). Aright weight part (6C) of the counterweight (6) is provided with an exhaust opening (29) in a position facing the outflow opening (28) for causing cooling air having flowed out from the outflow opening (28) to be discharged to an exterior.

An engine-driven working machine capable of reducing an opening of an outer case to be small, and decreasing the number of components is provided. An engine-driven working machine 10 is a generator in which an inverter 27 is provided at a suction side of a cooling fan 17, and a fuel tank 25 is provided over the inverter 27. The generator 10 includes an intake port 36 that is formed in an outer case 12, and a first air guide passage 61 that is formed by a tank bottom portion 38 of the fuel tank 25. The intake port 36 is formed in a lower side part 12b of a tank front wall 37, in the outer case 12. The first air guide passage 61 is formed by the tank bottom portion 38that is inclined with a falling gradient toward the inverter 27 from the intake port 36.

A shield assembly that may be disposed within an engine compartment of an agricultural vehicle, the shield assembly includes a plurality of shields that may block buildup of debris within the engine compartment. At least one shield of the plurality of shields includes a sloped surface that may direct debris away from the engine compartment. The shield assembly also includes a plurality of ducts formed between the plurality of shields. The plurality of ducts may redirect cooling fluid from a cooling fan package to the engine compartment to remove debris from within the engine compartment.

A genset enclosure includes a frame system, a plurality of side panels, a plurality of roof panels, a first connector, and a second connector. The frame system includes a plurality of interconnected frame members. The plurality of side panels are coupled to opposing sides of the frame system. The plurality of roof panels are coupled to a roof of the frame system and extend between the opposing sides of the frame system. The plurality of roof panels are oriented perpendicular to the plurality of side panels. The frame system, the plurality of side panels, and the plurality of roof panels together define an enclosure portion having a first open end and a second open end. The first connector and second connector are engageable with one another and are coupled to the frame system along a perimeter of the first open end and the second open end, respectively.

A heat storage cover is provided in an engine room. The heat storage cover covers an engine from above and surrounds the periphery of an upper portion of the engine to internally store, through the medium of air, heat dissipated from the engine and block upward heat dissipation. The engine includes an air inlet for introducing, into a combustion chamber, high temperature air obtained by the heat storage cover blocking the upward heat dissipation.

An apparatus and method of controlling heat of an engine compartment when stopped are provided. The apparatus and method of controlling heat of an engine compartment improve fuel efficiency by managing heat of the engine compartment when a vehicle is stopped after driving.
