During operation under fuel cutoff control, the fuel cutoff control is interrupted when a decrease in temperature of cooling water from a temperature of cooling water that is detected at a start of the fuel cutoff control reaches or exceeds a second specified value under conditions that a degree of opening of an air mix door is greater than or equal to a predetermined opening degree and that a temperature setting is not raised in an operation unit.

Various disclosed embodiments include illustrative door assemblies, vehicles, and methods of assembling door assemblies. In an illustrative embodiment, a seat includes a base section, a back section, a first section of duct, and one or more vents couplable to the first section of duct. The first section of duct is configured to receive air from an air supply source and the first section of duct is disposed at least partially within the base section. The one or more vents are disposed at an aft surface of a section chosen from the base section and the back section.

A diffusing vent assembly may include a diffuser base and a diffusing head. The diffuser base may include a mounting flange, a collar extending from the mounting flange, and a ductwork fixation channel. The collar may span an infra-ceiling space of a vehicle. The diffusing head may include a diffuser vane configuration, a rotational flange surrounding the diffuser vane configuration, and an air blade. The diffuser base and the diffusing head further comprise complementary rotational securement members that permit rotation of the diffusing head relative to the diffuser base. The air blade may extend through the collar of the diffuser base. Installing the diffusing vent assembly may include engaging the ductwork fixation channel with a supply duct, inserting the diffusing head into the diffuser base, and securing the diffusing head and the diffuser base using the complimentary rotational securement members.

Disclosed is an air conditioner for a vehicle, the air conditioner having an improved guide structure capable of increasing an air volume by preventing a collision between air flowing through an upper passage and air flowing through a lower passage. The air conditioner for a vehicle comprises: an air conditioning case having an air passage formed therein and an air outlet which includes a defrost vent and a face vent; and a heat exchanger for cooling and a heat exchanger for heating, which are provided in the air passage of the air conditioning case. The air conditioner for the vehicle further comprises: a temperature door arranged between the heat exchanger for cooling and the heat exchanger for heating in order to adjust the degree to which cold air, which has passed through the heat exchanger for cooling, is heated by the heat exchanger for heating; a cold air passage through which cold air that has passed through the heat exchanger for cooling bypasses the heat exchanger for heating; a warm air passage through which cold air that has passed through the heat exchanger for cooling passes through the heat exchanger for heating; a cold air guide unit for guiding the cold air downstream of the heat exchanger for cooling; and a warm air guide unit for guiding the warm air downstream of the heat exchanger for heating.

A heat exchanger of an electrically driven motor vehicle, which includes a tube/rib block having a multiplicity of tubes and having a multiplicity of ribs. The tubes being arranged essentially in parallel to each other and spaced a distance apart, and the ribs each being arranged between two adjacent tubes. The ribs touching the two adjacent tubes, at least one manifold being arranged on one of the sides of the tube/rib block for the purpose of supplying fluid to tubes of the tube/rib block and for removing fluid from tubes of the tube/rib block. A cover device is arranged downstream and/or upstream from the tube/rib block for controlling the air flow through the tube/rib block temporarily or in certain regions for the defined removal of water from the tube/rib block. A method for operating a heat exchanger is also provided.

A heating, ventilation, and air conditioning (HVAC) door assembly includes a first HVAC door rotating about a first axis, a second HVAC door rotating about a second axis that is nonparallel with the first axis, an actuator, a mode cam. The mode cam is engaged with the actuator and controls movement of the first HVAC door and the second HVAC door.

Disclosed is an air conditioning apparatus for a vehicle, the air conditioning apparatus being applicable to an autonomous vehicle, etc. having console removed therefrom by ensuring a lower space of a driver's seat in a front part of the vehicle and being capable of preventing condensate water from flowing backward. The air conditioning apparatus for a vehicle comprises: an air conditioning case having an air flow path formed therein and a plurality of air discharge ports; and a cooling heat exchanger and a heating heat exchanger provided in the air flow path of the air conditioning case and exchanging heat with the air passing through the air flow path, wherein the air discharge ports include a front seat air discharge port and a back seat air discharge port, and the back seat air discharge port is arranged under the heating heat exchanger in the direction of gravity.

The present invention relates to an air conditioner for a vehicle, which includes an air-conditioning case (200), and at least one door (100) mounted to be opened and closed at a predetermined position, wherein the door (100) is formed integrally with an arm pivot (140), and the arm pivot (140) includes a pin part, and ribs formed integrally with both sides of the pin part to reinforce rigidity of the pin part and offset noise. The air conditioner further includes distortion preventing parts formed on a rotary shaft to be dented and to be crossed to each other, thereby reducing a transformation rate of the door and securing accuracy of the pin part.
