Title: Room heating device of car mounted with water-cooled engine
Inventor: SAKURAI SHIGERU
IPC: B60H1/08
Filed: 1982-07-07
Abstract: PURPOSE:To obtain a sufficient degree of room heating temperature at cold time of an engine, by taking out cooling water from a water jacket for central cylinders divided by partitions in the cooling water jacket, heating the cooling water through a heat exchange with exhaust gas, and then guiding the water to a room heating heater core. CONSTITUTION:A cooling water jacket 1 in a 4-cylinder engine E is divided by partitions P1, P2 into a high temperature part water jacket 1a and a low temperature part water jacket 1b. Then cooling water in the low temperature part water jacket 1b flows in through a circulative route 20 interposing a radiator 21 by driving of a pump 23 and is cooled, and then returned from a flow inlet 17 into the water jacket 1b. While cooling water in the high temperature part water jacket 1a is firstly guided to a heat exchanger 10 by driving of a pump 22 and heated by exhaust gas flowing in an exhaust passage 9, and then guided to a heater core 5 of an air conditioner to heat air conditioning air, thereafter the water is returned from a flow inlet 2 into the water jacket 1a. At completion of warming operation, a thermostat valve 16 is opened to the side of a bypass passage 14, and the cooling water is cooled by a radiator 15.

Title: Damping force control device
Inventor: HARAYOSHI MITSUHIKO
IPC: B60G17/08
Filed: 1995-05-17
Abstract: PURPOSE: To facilitate car height adjustment, attitude control, and comfortableness control for a vehicle, requiring less energy. CONSTITUTION: A device is provided with an air pressure supply/discharge means 14 to supply/discharge air to/from a return chamber 12 of a double-acting type actuator 31 which absorbs relative attitude change between a car body and a wheel by supply and discharge of hydraulic oil. Separately from actuation of the actuator 31 by a hydraulic pump 38, air is supplied to/discharged from the return chamber 12 by an air pressure supply/discharge means 14, so relative position between the car body and the wheel is changed. A power source for adjusting car height thus becomes the one requiring less energy that is separate from a hydraulic system to perform attitude control and comfortableness control, thereby car height adjustment, attitude control, and comfortableness control of a vehicle can thus be performed, requiring less energy.

Title: Exhaust control device for engine
Inventor: SAITO FUMIHIKO
IPC: F01N3/28
Filed: 1992-05-12
Abstract: PURPOSE:To keep high purification efficiency of NOx by suppressing bad influence to a lean operation and increase of an external load, and preventing deterioration of a lean NOx catalyst which may be caused by oxygen adsorption. CONSTITUTION:During lean operation, it is judged whether a catalyst resisting temperature T0 is exceeded by a value which is obtained by a presumed temperature increasing rate T2 due to temperature-increasing operation to a catalyst temperature T1 11 periodically by a CPU 12 or not (S13). When the resisting temperature T is exceeded, a temperature-increasing operation is executed by catalyst heating 19 (S14). Other than the resultant periodical reduction of adsorbed oxygen, it is reduced every time when a multiplied value of an oxygen rate passing through a lean NOx catalyst exceeds a specified value. Operation can be carried out with an air-fuel ratio being temperarily shifted to rich instead of heating of the catalyst as a reduction means for the adsorption oxygen.
