    Abstract: 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.

    Abstract: 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.
