Abstract: PURPOSE:To favourably control the air-fuel ratio by changing the standard signal to the larger value and varying the feedback control constant for the air-fuel ratio to the rich side, when a gas detecting element detects a high temperature. CONSTITUTION:A gas detecting element M1 is connected with a high temperature judging means M4, which is connected with a standard signal varying means M5 and a feedback control constant varying means M6, and when the gas detecting element detects a high temperature, the standard signal is changed to the larger value, and the feedback control constant for air-fuel ratio is changed to the rich side. Therefore, the erroneous control of the air-fuel ratio to the lean side can be prevented, and the air-fuel ratio can be controlled favourably.

Abstract: PURPOSE:To make it possible to accurately measure the angular change of matter moving at a high speed, by obtaining the angular displacement of the moving matter by the change in the coordinates of an incident point of reflected light. CONSTITUTION:The light L from a light source 21 passes through a lens 22 and a glass plate 6 to enter the reflective mirror 1 provided to the upper surface of piston P and is reflected to be incident to an incident position detector 3 and the output of said detection 3 is inputted to an operation part 5. A rotary angle sensor 4 for detecting the moving position of the piston P is provided to a crank shaft and the angle signal 4a thereof is inputted to a timing circuit 57 which, in turn, counts the timing data T outputted from CPU56 every when the angle pulse in the signal 4a is inputted to emits a sample hold start signal 57a. The signal 57a is sent to an A/D converter circuit 53 through a sample hold circuit 52. CPU56 reads each signal sent through a data bus 58 and subjected to A/D conversion to calculate the incident point of the incident light of the detector 3. If the change in the coordinates of an incident point R is known, the angular change of the piston P can be measured.

Abstract: PROBLEM TO BE SOLVED: To improve a mechanism to suppress surge due to recirculation of working fluid in a compressor for supercharging and obtain a high surge suppressing effect even by a working fluid recirculating amount being as low as possible. SOLUTION: A compressor for supercharging suppresses a surge by effecting recirculation of a part of working fluid energized by at least a part of the working fluid energizing flow path of a rotor to the inlet part of the working fluid energizing flow path. A direction of the outlet of the working fluid recirculating path is kept such that working fluid recirculation of which is effected is injected against working fluid, flowing in the working fluid energizing flow path, in a state to be followed by a peripheral speed component reverse to the rotation direction of a rotor.

Abstract: PURPOSE:To prevent a knocking control device which controls the spark retardation compensating value for the timing of ignition upon occurrence of knocking, from controlling the timing of ignition in such a way that the spark retardation becomes excessive, by providing a compensating means for compensating the spark retardation compensating value in its decreasing direction upon occurrence of transient operation of an engine. CONSTITUTION:In knocking control device, there is provided an ignition timing compensating means MC which receives output signals from a knock sensor MB and which averages output signals from the knock sensor MB so as to calculate a knocking judging level in order to determine occurrence of a knocking after comparing the judging level with an output signal from the knock sensor MB. Upon occurrence of knocking, the spark retardation compensating value for the timing of ignition is controlled. In this arrangement, there is provided a transient operation detecting means MD for detecting the operating condition of an engine MA so as to detect a transient operation during which a variation in engine rotational speed exceeds a predetermined value. Upon detection of the transient operation, a compensating means ME compensates the spark retardation compensating value in its decreasing direction.
