Publication number: 20020046563Abstract: The invention provides an electronic control unit for controlling an air/fuel ratio of an engine having a lean NOx catalyst in its exhaust system in order to prevent the decrease of the fuel efficiency without deterioration of the drivability due to rich operation to reduce the NOx catalyst. The electronic control unit comprises: air/fuel ratio control means for changing the air/fuel ratio to a rich side when the amount of NOx occluded by the lean NOx catalyst exceeds a predetermined value and changing said air/fuel ratio back to a lean side when a first predetermined period has elapsed; lagging means for lagging ignition timing in synchronization with the air/fuel ratio changing to the rich side by said air/fuel ratio control means; and decrementing means for decrementing amount of the ignition timing lagged by said lagging means by a predetermined amount when a second predetermined period shorter than said first predetermined period has elapsed after the air/fuel ratio changing to the rich side.Type: ApplicationFiled: September 27, 2001Publication date: April 25, 2002Inventors: Masayuki Wakui, Junichi Suzuki, Masayuki Ueno, Osamu Kitamura

Publication number: 20020046570Abstract: Heat exchange is performed between a discharge side refrigerant and a suction side refrigerant also at the time of a heating operation. By this, a liquid phase refrigerant containing lubricating oil in the suction side refrigerant is heated by the discharge side refrigerant, and the liquid phase refrigerant is vaporized also at the time of the heating operation, so that the amount of the liquid phase refrigerant sucked into a compressor is decreased. Accordingly, the increase of compression work of the compressor is prevented, and an opening area of an oil return hole can be expanded to such a degree that an optimum amount of lubricating oil is attained at the time of the heating operation.Type: ApplicationFiled: October 17, 2001Publication date: April 25, 2002Inventors: Satoshi Itoh, Yoshitaka Tomatsu, Motohiro Yamaguchi, Yasushi Yamanaka, Toshio Hirata
