    摘要： Disclosed herein is an air/fuel ratio control system for an internal combustion engine. The system includes a first oxygen density sensor element, a second oxygen density sensor element having a slower detection response speed than the first sensor element, an air/fuel ratio control unit for controlling the air/fuel ratio of the engine on the basis of results of a comparison between a detection value from the first sensor element and a standard value, and an air/fuel ratio control correction means for effecting a correction to the air/fuel ratio control by the air/fuel ratio control unit on the basis of results of comparison between a detection value from the second sensor element and a second standard value. An air/fuel ratio controlling oxygen density sensor is also disclosed. The sensor is constructed of a first oxygen density sensor element and a second oxygen density sensor element for detecting the density of oxygen in exhaust gas at a slower detection response speed compared to the first sensor element. The first and second oxygen density sensor elements are both provided on a common base member.

    摘要： In a thermostat failure diagnosis apparatus for an internal combustion engine in which a failure diagnosis of a thermostat can be effectively made, in the case where, after starting of the engine, an intake air quantity of the engine or a parameter related to the intake air quantity is equal to or higher than a predetermined value, and a cooling water temperature is equal to or higher than an intake air temperature (outside air temperature), on the basis of a time in which a rising quantity in the cooling water temperature at an upstream side of the thermostat reaches a predetermined value, or a time in which the cooling water temperature rises to a predetermined temperature, the failure of the thermostat is judged. By this, the failure diagnosis of the thermostat can be rationally made only when the engine generating heat quantity is large to some degree to prevent erroneous diagnosis.

    摘要： In a swash plate type axial piston pump, a swash plate 23 is fixed and supported in a cabinet while being inclined with respect to the center axial line of a rotary shaft 3. A cylinder block 15 having a plurality of cylinders 13 is attached to the rotary shaft 3 so that the cylinder block 15 slides of the rotary shaft 3 in the axial direction thereof and is rotated integrally therewith. Each one end of a plurality of pistons 21 is slidingly engaged with the cylinder 13 and the other end thereof is abutted against the swash plate 23 through a shoe 25. A valve plate 31 having a suction port 33 and a discharge port 35 is disposed so as to be abutted against the inner surface of the cabinet 1 and the bottom the cylinder block 15 so that a suction path 39 and a discharge path 41 in the cabinet 1 are selectively communicated with a pump chamber 14 in each cylinder through the suction port 33 and the discharge port 35. An operating oil is supplied to the sliding portion between the valve plate 31 and the bottom of the cylinder block 15 by a lubrication means. With this arrangement, since the operating oil is positively supplied to the sliding portion being rotated of the swash plate type axial piston pump, the sliding portion is sufficiently lubricated even if the pump is started to thereby prevent the dry state of the pump.

    摘要： An air/fuel ratio control system is provided for use with an internal combustion engine. The system includes a first air/fuel ratio detector arranged on an upstream side of a catalytic converter so as to detect the air/fuel ratio of the engine from components of exhaust gas, a second air/fuel ratio detector arranged in the exhaust system and having a detection response speed slower than the first air/fuel ratio detector, a device for controlling the air/fuel ratio of the engine on the basis of results of a comparison between a detection value from the first air/fuel ratio detector and a predetermined first reference value, a device for effecting a correction to the control of the air/fuel ratio by the air/fuel ratio control device on the basis of results of a comparison between a detection value from the second air/fuel ratio detector and a predetermined second reference value, and a device for shifting the second reference value to a lean air/fuel ratio side in a specific operation state of the engine.
