摘要： A plug hole pipe 79 has thread grooves 81 formed on an outer circumferential surface thereof and causes a spark plug 11 to be pressed against a cylinder head 51 when the plug hole pipe is fixedly attached to the cylinder head 51 through screw engagement. The spark plug 11 is configured such that no thread grooves are formed on the outer circumferential surface of a front end portion 25 of a metallic shell 19, and can be vertically inserted into a plug disposition hole 51a formed in the cylinder head 51. By vertically inserting the spark plug 11 into the plug disposition hole 51a while the orientation of a ground electrode 21 is set beforehand in relation to the cylinder head 51, the ground electrode 21 can be oriented in a specific direction.

As a result, a space for installing a coil body portion (37) can be secured largely in the inside of the protection metal pipe (31), so that the installation space need not be changed largely when the ignition coil is mounted in a cylinder head.

The residual oxygen concentration of the second processing chamber 5 is determined on the basis of a second oxygen pump current flowing between the second inner and outer electrodes 10 and 11, whereby the concentration of combustible gas components contained in the gas under measurement is determined.

摘要： A device and method for measuring combustible-gas concentration and a device and method for measuring hydrocarbon-gas concentration, which exhibit low dependence on oxygen concentration variations as well as low temperature dependence. Paste is applied to the inner surface of a closed-bottom cylindrical solid electrolyte element, thereby forming a layer serving as a reference electrode. Plating with platinum is performed, so as to form a layer serving as a first detection electrode, on the outer surface of the solid electrolyte element only at a portion extending from an end portion of the solid electrolyte element to the vicinity of the interface between a heating resistor and a heating-resistor lead portion, which are formed within a heater element contained in the cylindrical solid electrolyte element. Paste which contains gold powder and 10 parts of indium oxide is applied onto the platinum-plating layer so as to form a layer serving as a second detection electrode, followed by firing. Subsequently, a diffusion layer containing spinel is formed by thermal spraying on the surface of a detection electrode. The heater element is disposed in the solid electrolyte element such that an end portion abuts an inner bottom portion of the solid electrolyte element. Lead wires for measuring internal resistance, which extend from the reference electrodes, and a lead wire extending from the detection electrode are connected to a temperature controller.

摘要： The present invention provides an apparatus for measuring the concentration of a constituent to be detected in exhaust gas, which apparatus is capable of detecting with a high accuracy the concentration of the constituent to be detected in exhaust gas even though oxygen concentration in the exhaust gas varies. In an exhaust gas sensor 1 for use in the measuring apparatus, exhaust gas is introduced into spaces 15, 16 on both sides of an oxygen concentration cell element 4, and the oxidation catalyst activities of first to third electrodes 11 to 13 are adjusted so that there occurs a difference between the space 15 and the space 16 in consumption of the constituent to be detected, which consumption is caused by the oxidation of the constituent. Thus a concentration cell electromotive force is generated in the oxygen concentration cell element 4, and an oxygen pump element 3 pumps oxygen into or out of the space 15 so that the electromotive force is held at an target value EC not more than 10 mV. The pump current at this time is taken as the detection output on the constituent to be detected. The strengths of the oxygen concentration cell element 4 and of the oxygen pump element 3 can be increased by the provision of an integrated sintered body in which the elements 4 and 3 are laminated together with the space 15 formed between the first electrode 11 and the second electrode 12. Besides, the accuracy of detecting the constituent to be detected can be improved by the control over the temperature of the oxygen concentration cell element 4 and by the temperature compensation to the pump current.
