摘要： A gas component detector has a detector element of a metal oxide held on one end of a ceramic body. The detector element is electrically connected to a pair of electrodes and the pair of electrodes are in turn welded to a pair of sub-lead-lines to deliver a detected electric signal from the detector element. The pair of electrodes and sub-lead-lines are inserted in a pair of through holes of the ceramic body and the pair of electrodes are fixed by an inorganic adhesive within the through holes. The openings of the pair of through holes of the ceramic body at the opposite end with respect to the detector element are closed by a sealing material of an electrically insulating metal oxide.

摘要： A gas component detection apparatus comprises a first and a second gas sensing elements each composed of a metal oxide which exhibits variable electric resistances according to gaseous components and temperatures of gases to be detected. A catalyst is carried at least by the first sensing element for promoting oxidation reactions of the gaseous components of the gases. A first pair of electrodes are inserted into those portions of the first sensing element which are subjected to catalytic action of the catalyst. Into the portions of the second sensing element which are not subjected to catalytic action are inserted a second pair of electrodes. The first pair of electrodes sense a variation in electric resistances resulting from the gaseous components and temperatures of the gases, while the second pair of electrodes detect an electric resistance variation related mainly upon the gas temperatures. Consequently, an output signal reflecting substantially only the gaseous components of the gases is produced by offsetting both of the electric resistances separately sensed utilizing a suitable electric circuit.

摘要： A gas component detection apparatus for detecting gaseous components of exhaust gases from a combustion device. There is provided a gas component detecting element composed of semiconductive metal oxides and having its outer surface partly exposed to the exhaust gases. A catalyst layer is carried on the larger part of the latter outer surface of the detecting element. A pair of electrodes are provided for sensing the electric resistance exhibited at the portion of the detecting element which carries the catalyst layer. Also another electrode is provided for cooperating with one of the above pair of electrodes to detect the electric resistance exhibited at the portion of the detecting element which does not carry the catalyst layer. The former portion of the detecting element exhibits variable electric resistances resulting from concentrations of the gaseous components and the temperatures of the exhaust gases, while the latter portion thereof exhibits variable electric resistances related mainly upon the temperatures of the exhaust gases. Consequently, an output signal reflecting substantially only the gaseous components of the exhaust gases is produced by offsetting both of the electric resistances separately sensed utilizing a suitable electric circuit.

摘要： A gas component detection apparatus for detecting gas components contained in an exhaust gas from a combustion device and determining an air-fuel ratio of an air-fuel mixture supplied thereto. A gas component detecting element composed of a semiconductive metal oxide is contacted by the exhaust gas andexhibits variable electric resistances according to the concentrations of the gas components. The electric resistance is taken out as an electric signal through two electrodes disposed either on the surface of the detecting element exposed to the exhaust gas or within the detecting element adjacent that exposed surface. A porous coating layer having an exhaust gas permeability covers the surface of the detecting element exposed to the exhaust gas so as to prevent poisonous substances contained in the exhaust gas from depositing on that exposed surface of the detecting element. The coating layer is formed of a metal oxide having electrically insulating properties and carries therein a catalyst promoting an oxidation reaction of the exhaust gas. The detecting element exhibits an abruptly changed electric resistance when the actual air-fuel ratio of the air-fuel mixture supplied into the combustion device is deviated from a stoichiometrical air-fuel ratio, thereby enabling the control of the air-fuel ratio of the air-fuel mixture.

摘要： A spark plug includes a body of dielectric substance mounted on one of central and earth electrodes and having polarization effects. A gap for capacitive discharge is defined between the body of dielectric substance and the other of the electrodes, and a gap for inductive discharge is defined between the electrodes, which gap for inductive discharge is larger in dimension than the gap for capacitive discharge. With the arrangement, capacitive discharge to be produced in the early stage of discharge is caused at low discharge breakdown voltage due to polarization effects of the body of dielectric substance, and inductive discharge taking the main part of discharge for ignition is produced by utilizing the capacitive discharge of low voltage as trigger, thereby lowering discharge breakdown voltage to improve ignition performance of the spark plug.
