In a thermal fluid system, a control valve includes a flow valve and a solenoid pilot valve. The flow valve has an inlet and an outlet; a control chamber for receiving a pilot pressure; and a valve member operable by the pilot pressure to selectively open and close a fluid path from the inlet to the outlet. The pilot pressure acts in a closing direction of the flow valve. The pilot valve provides the pilot pressure to the control chamber and is a 3/2 way valve with a first port in fluid communication with the control chamber, a second port to be connected to a pressure source, and a third port. The pilot valve has a first position connecting the first port with the second port and a second position connecting the first port with the third port.

An engine room heat exhausting structure configured to discharge heat from an engine room, is provided, which includes an engine room accommodating an engine with cylinders lined up in a front-and-rear direction of a vehicle, a wheelhouse provided outside the engine room in a vehicle width direction, an exhaust emission control device disposed between the engine and the wheelhouse, a wheelhouse liner configured to protect an inner wall of the wheelhouse, a discharging part provided rearward of the exhaust emission control device and configured to discharge into the wheelhouse a part of air cooled the exhaust emission control device, and a guiding part provided to the wheelhouse liner and configured to guide the air discharged into the wheel house to underneath the vehicle in a rear part of the wheelhouse.

A straddled vehicle including a radiator, a radiator fan disposed behind the radiator and configured to generate air passing through the radiator and flowing rearward, a fan cover disposed behind the radiator fan and including a lateral blowing port configured to blow out sidewards the air flowing rearward from the radiator, a side cover covering the radiator laterally and having an opening formed therein, an inner panel disposed between the side cover and the radiator, to thereby define an accommodation space between the inner panel and the side cover, and an electrical component disposed in the accommodation space. The inner panel includes a slope that is located rearward of the radiator, slants with respect to aright-and-left direction of the straddled vehicle, is configured to lead the air blown out from the lateral blowing port to the opening in the side cover, and divides the accommodation space.

This disclosure pertains to a device for removing air from a coolant liquid of a coolant system. The device has a body, a swirl pot having a first fluid outlet, and a pump end wall formed with the body and connected to the first fluid outlet. The pump end wall provides a second fluid outlet.

A fan structure is provided with a fan, a fan support, a base, and a motor. The fan is provided with a rotational shaft rotatable about a rotational shaft, and a blade coupled to the rotational shaft to rotate about the rotational axis together with the rotational shaft. The fan support rotatably supports the rotational shaft. The base slidably supports the fan support so as to be slidable in the sliding direction. The motor includes a motor main body supported by a fan support opposite to the rotational shaft of the fan in the axial direction along the rotational axis, and a motor rotational shaft connected to the rotational shaft so as to rotate the rotational shaft.

A system for flushing a cooling water pathway in a marine propulsion device includes a water control device, an electric power control device, a data communication module, and a controller. The controller controls the water control device to supply the water from a water source to the cooling water pathway to flush the cooling water pathway. The controller controls the electric power control device to supply electric power to the marine propulsion device during the flushing. The controller determines whether to end the flushing or not. When it is determined to end the flushing, the controller controls the electric power control device to stop the supply of electric power to the marine propulsion device, and controls the data communication module to notify the end of the flushing to a terminal of a user of the marine propulsion device.

An object of this invention is to efficiently warm up a catalyst and keep its temperature. Provided is a drive system, including: an internal combustion engine; a catalytic unit configured to purify an exhaust gas from the internal combustion engine; a motor used for at least one of drive or regeneration; and a flow path formed so as to allow an oil-based medium for lubricating the motor to flow in the vicinity of the catalytic unit. The oil-based medium is heated in the motor and exchanges heat in the catalytic unit to heat the catalytic unit.

An air release structure of an integrated flow control mechanism includes a flow control housing, a radiator nipple provided on an upper portion of the flow control housing and forming a bypass passage portion together with the flow control housing, a float provided in the bypass passage portion and an elastic member to support the float elastically and to selectively open the bypass passage portion.
