摘要： PROBLEM TO BE SOLVED: To resolve trouble in shifting from a high thermal load state to a steady state, hardly impair air conditioning in a rear seat having no seat sensor, and improve comfort of a rear seat occupant by directly supplying conditioned air. SOLUTION: A front passenger seat, a seat behind a driver's seat, and a seat behind the front passenger seat are provided with seat switches 61-63 for detecting presence of occupants. When a temperature within a cabin is very high with the front passenger seat vacant, both driver's seat side and front passenger seat side center louvers 43, 46 are swung with the driver's seat as the center so that a lot of cold air is directly supplied to a driver from driver's seat side and front passenger seat side center grilles 41a, 41b. When an air- conditioning state becomes a steady state, the driver's seat side and front passenger seat side center louvers 43, 46 are swung with the driver's seat and the front passenger seat as the respective centers so that the cold air circulates around the whole cabin.

摘要： PROBLEM TO BE SOLVED: To burn a burner in a stable manner while suppressing an increase of the manufacturing cost of a heating device for a vehicle. SOLUTION: A pipe 32 for a burner is connected to a side of an intake pipe 11 from an EGR valve 31. When an engine 10 is stopped, exhaust gas of the burner 22 is released to the side of a catalyst 15 by closing a throttle valve 13 also opening the EGR valve 31 and the exhaust gas of the burner 22 is discharged to an intake side of the engine 10 by opening the throttle valve 13 when the engine 10 is operated. In this way, the exhaust gas of the burner 22, after it is purified by the catalyst 15, is released into the atmosphere with a noise reduced by a muffler 16, so that the exhaust gas of the burner 22 can be purified without newly providing a catalyst and a muffler for the burner 22. And the exhaust gas of the burner 22, by sucking it to the engine regardless of an opening/closing condition of the EGR valve 31 when the engine 10 is operated, can be discharged without using a (displacement) type blower, combustion of the burner 22 can be operated in a stable manner.

摘要： PROBLEM TO BE SOLVED: To cool exhaust to reflux (recirculate) without newly providing a heat exchanger for an exhaust recirculating device. SOLUTION: Exhaust is recirculated to an intake side of an engine 1 after a heat exchange of the exhaust gas and cooling water by a combustor 11 when it is stopped. In this way, exhaust to reflux (recirclulate) can be cooled without newly providing a heat exchanger for an exhaust recirculating device, so that a space for setting up the heat exchanger does not need to be ensured newly in an engine room, and an increase in manufacture cost of a vehicle can be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide an air cleaner for a vehicle capable of deodorizing a cabin at the time of parking. SOLUTION: A deodorizing filter 6 used to an air cleaner 1 is constituted by attaching a photocatalyst particle such as titanium oxide etc., to an adsorbent (e.g. an activated carbon filter) composed of porous material, and is arranged in the lower part of a spit hole 8 exposed to sunshine. A blower 4 for generating an air flow in the air cleaner 1 case 2 actuates a solar battery 3 as an electric power source. Consequently the blower 4 can be actuated even at the time of parking, to operate the air cleaner 1 similarly at the time of travel to purify a cabin inside. Activated carbon used to the filter 6 lowers the adsorption capacity of the activated carbon with the increase of the adsorption quantity of an odor component, but the adsorption capacity of the activated carbon can be recovered by the action of a photocatalyst. Since the photocatalyst is activated by receiving the ultraviolet ray of the sunshine, the filter 6 can be refreshed at the time of not only the travel of a vehicle but also even parking.

摘要： PROBLEM TO BE SOLVED: To prevent the reduction of the heat radiating capacity of a radiator while realizing the reduction of the warming up operation time. SOLUTION: A shroud 6 is provided between a radiator 4 and a water cooling engine 1, a first air passage 61 (the first and the second blowing out holes 61a and 61b) to blow out the air to the engine 1 and its accessary is formed at the upper side of the shroud 6, and a second air passage 62 to discharge the air passed through the radiator out of the engine room 3 is formed at the lower side. As a result, the striking of the air directly to the water cooling engine 1 is prevented, and the turning in of the air up to the upstream side after passing through the clearance between the inner wall side of the engine room 3 and the radiator 4 (a reverse flow) is also prevented. Consequently, the reduction of the heat radiating capacity of the radiator 4 can be prevented while realizing the reduction of the warming up operation time.

摘要： PROBLEM TO BE SOLVED: To improve the room heating effect at the winter season, and the engine cooling effect at the summer season, by a simple cooling water circuit. SOLUTION: In the passage of a cooling water force feeding by a mechanical driving type water pump 6, an electric water pump 14 is arranged at the flowing position where the cooling water flows by converging, to a radiator 2 and a heater core 7 for heating, while a check valve 15 to let flow the cooling water only in one direction from the suction side of the electric water pump 14 to the delivery side is provided parallel to the electric water pump 14. When the electric water pump 14 is operated, the cooling water of the total flow rate by the mechanical driving type water pump 6 and the electric water pump 14 can be let flow to the radiator 2 and the heater core 7 for heating.

摘要： PROBLEM TO BE SOLVED: To obtain a heat-exchanger for vehicle having longer breadthwise dimensions than the vertical dimensions in which the temperature difference of the air being diffused in the breadthwise direction at a heat-exchanging core part is reduced by dividing the heat-exchanging core part into a plurality of core parts and flowing a heat source fluid at one and the other core parts reversely in the breadthwise direction at the core part. SOLUTION: The heat-exchanging core part 11 of a heat-exchanger for warming a vehicle comprises a flat tube 11a and a corrugated fins 11b and the breadthwise dimensions W are set extremely larger than the vertical dimensions H. The heat-exchanging core part 11 is divided vertically into first and second core parts 110, 111 and the inside of tanks 17, 18 are partitioned vertically by arranging partitioners 19, 20. Hot water from an inlet pipe 21 is fed from one end toward the other end of the core part in the breadthwise direction at the first core part 110 whereas hot water from an inlet pipe 22 is fed from the other end toward one end of the core part in the breadthwise direction at the second core part 111.

摘要： PROBLEM TO BE SOLVED: To provide a position control device for a sliding door that can be stopped in three preset specified positions. SOLUTION: In case of switching from a face mode to a bi-level mode, for instance, a servo motor is driven to move a sliding door 18 toward the other end side in a moving direction. With the movement of the sliding door 19, a first switch operating part 24a turns on a first switch 35, and a second switch operating part 24b turns on a second switch 36. When the first switch 35 and second switch 36 are turned on, current carrying to the servo motor is cut off, and the sliding door 19 is stopped in a third stop position.

摘要： PROBLEM TO BE SOLVED: To avoid shortage of a refrigerant in a refrigerating cycle and shortage of oil circulation irrespective of changes in the degree to which freezing of a coolant advances. SOLUTION: Solenoid valves 21, 22 are closed, and in that state a compressor 1 is operated. Thereby a refrigerant remaining in a cold-storage-type evaporator 15 is recycled into a receiver 6. Thereafter, the solenoid valve 21 is opened to allow the refrigerant to flow only to the cold-storage evaporator 15. Therefore, shortage of the refrigerant in a refrigerating cycle and shortage of oil circulation can be avoided irrespective of changes in the degree to which freezing of a cold storage material advances.
