摘要： A lip ring is attached to a piston so as to be rotatable relative to the piston in a circumferential direction, and a seal portion is provided between a ring attachment groove of the piston and an attachment portion of the lip ring. During a suction stroke, the lip ring can be rotated in a circumferential direction of the piston, thus distributing wear around the entire periphery of a lip portion of the lip ring. During a compression stroke, leakage of air from a compression chamber can be prevented by means of the seal portion provided between the ring attachment groove and the lip ring.

摘要： To increase the power generation efficiency of a microbial power generator by using an easy and inexpensive unit. Two plate-like cation-exchange membranes 31 are disposed in parallel in a tank 30. This arrangement allows an anode chamber 32 to be formed between the cation-exchange membranes 31. Two cathode chambers 33 are separated from the anode chamber 32 by using the respective ion-permeable nonconductive membranes 31. An oxygen-containing gas is made to pass through the cathode chamber 33. An anode solution L is supplied to the anode chamber, and, preferably, the anode solution is made to circulate. A biologically treated exhaust gas is used as the oxygen-containing gas to be supplied to the cathode chamber 33. Carbon dioxide in the biologically treated exhaust gas can promote transport of Na+ and K+ ions, and water vapor can increase the ion permeability, thereby increasing the power generation efficiency.

摘要： In an exhaust system for an internal combustion engine, including an upstream catalytic converter and a downstream catalytic converter, emission levels of exhaust gas are detected at positions upstream from the upstream catalytic converter, between the upstream and downstream catalytic converters, and downstream from the downstream catalytic converter, respectively. An air-fuel ratio is feedback controlled based on an emission level detected by the first emission sensor or feedback controlled based on an emission level detected by the second emission sensor when the engine operates in a specific vehicle operating condition. Deterioration of the downstream catalytic converter is detected based on an emission level detected by the third emission sensor while an air-fuel ratio is feedback controlled based on the emission level detected by the second emission sensor.

摘要： An engine exhaust purification system is provided with a catalyst in an exhaust line, and oxygen sensors disposed in the exhaust line upstream and downstream from the catalyst, respectively. Deterioration of the catalyst is judged based on a frequency ratio of reversal of an output from the downstream oxygen sensor with respect to a threshold value to an output from the upstream oxygen sensor with respect to a threshold value. The threshold value of the deteriorated oxygen sensor is changed so as to vary the frequency ratio of reversal.

摘要： An exhaust gas sensor in which a metal oxide semiconductor containing at least one member of a group of elements consisting of Sn, Fe, Ni and Co and Pt electrodes having ZrO.sub.2, deposited in the grain boundary are used. Such metal oxide semiconductors include, for example, SnO.sub.2, BaSnO.sub.2, BaSnO.sub.3, SrSnO.sub.3, and CaSnO.sub.3. The exhaust gas sensors are manufactured by mixing such compounds as BaCO.sub.3, SrCO.sub.3 or CaCO.sub.3 with SnO.sub.2 in equimolar ratio to react them in air at 1200.degree. C. for four hours. The compounds thus obtained were pulverized and Pt electrodes with ZrO.sub.2 were imbedded therein, then were molded into sensor chips. The chips thus molded were baked by heating in air. After the chip has been sintered the exhaust gas sensor was assembled. It comprised an insulating substrate of alumina, etc. having a recess provided at one end thereof in which the aforementioned sensor chip was housed. The electrodes on the chip were housed in grooves provided in the substrate with their ends connected with base metal outside leads. Then an alumina sheet was pasted on the substrate, leaving a gap along the circumferential rim of the chip, thereby shielding and protecting the electrode from the atmosphere.
