Abstract: A total amount of NO X (NO X IN) that flows into an NO X catalyst (18) between the time that air-fuel ratio control ends and the time that the air-fuel ratio control starts the next time, is obtained. A total stored amount (TSA), which is the sum of an oxygen stored amount (OSA) and an NO X stored amount (NSA) in the NO X catalyst (18) before the air-fuel ratio control started, is calculated based on the amount of reducing agent that has flowed into the NO X catalyst (18) during the air-fuel ratio control. The oxygen stored amount (OSA) is calculated by extrapolating a relationship between the total amount of N0 X (NO X IN) and the total stored amount (TSA). The relationship is established beforehand by executing the air-fuel ratio control with at least two levels.
Abstract translation: 流入NO X 催化剂（18）的总空气量（NO X IN） 控制结束，空燃比控制开始下一次的时间。 总存储量（TSA）是NO NO：X催化剂（18）中的氧存储量（OSA）与NO X存储量（NSA）的总和。 ）基于在空燃比控制期间已经流入NO X 催化剂（18）的还原剂的量来计算在空燃比控制开始之前的空燃比。 储氧量（OSA）通过外推总量N0 X （NO XIN> IN）和总储存量（TSA）之间的关系来计算。 预先通过执行至少两级的空燃比控制来建立关系。

Abstract: A protruding length L1 that is a distance between an inner circumference of a flow path through which fluid flows on an axis of a temperature sensor disposed in the flow path and the center of said temperature sensitive device is 50mm or more. A protruding location that is a distance between an inner circumferential surface of the flow path and the center of said temperature sensitive device on a cross section extending perpendicular to the axis of said flow path through the center of said temperature sensitive device is defined as L1 '. A flow path width that is a distance between intersections of the axis of the temperature sensor with the inner circumferential surface of said flow path when the temperature sensor is projected onto said cross section is defined as D1 . A relation of L1' / D1 is specified as a function of the value of D1 , thereby reducing heat transfer in an exhaust temperature sensor and enabling the temperature to be measured accurately.

Abstract: A temperature sensor including a temperature sensitive device which is disposed in a flow path through which fluid flows and whose electric characteristic changes as a function of temperature of the fluid in the flow path, signal lines connected at top end sides thereof to said temperature sensitive device through electrode wires and at base end sides thereof to lead wires for connection with an external circuit, a sheath member retaining the signal lines therein, and a holding member which holds an outer circumferential surface of said sheath member directly or indirectly through another member. The resonance (primary) frequency at a top end of the temperature sensor against acceleration in a radius direction of the temperature sensor is 480Hz or less, thereby reducing the transmission of vibration to the top end of the temperature sensor to avoid the breakage of the temperature sensitive device and the disconnection of the electrode wires 502102 even when the temperature sensor resonates.

Abstract: A method of manufacturing a spark plug having an attachment fitting 2, an insulator 3, a center electrode 4 and an earth electrode 5. While fixed to attachment fitting 2, earth electrode 5 has a convex part 510 formed by projecting a part of an opposed surface 51 toward center electrode 4, and a concave part 520 formed toward the opposed surface 51 from the earth electrode's back surface 52. The convex part 510 is disposed so that the extension of a shaft center of the convex part 510 passes through the area in which the concave part 520 is formed. The relation S1>=s is realized when an area of an opening of the concave part 520 is set to S1 and an average cross-section area of a cross section of the convex part 510 perpendicular to an axial direction of the spark plug is set to s.

Abstract: Carbon fouling adhered on an insulator tip of a spark plug of the present invention is burnt down by a leak current during an inductive discharge period, due to a promoted ionization before beginning a capacitive discharge, in such an arrangement of a central electrode that a border portion of a body and narrowed portion is positioned in an insulator. The carbon burning-down effect is further improved by a narrow projection provided with an earth electrode, due to increased inductive energy and extended inductive discharge time period. This is because an electric field in a discharge gap is raised, thereby decreasing a discharge voltage and suppressing an energy emitted from a coil during the capacitive discharge.

Abstract: A spark plug and a production method thereof is provided which is designed to improve the high temperature oxidation resistance of a ground electrode without sacrificing the mechanical strength of a weld of the ground electrode with a metal shell. The ground electrode is made of a Ni-based alloy containing 10% or more by weight of Cr and 1.5% or more by weight of Al and joined to the metal shell by resistance welding in a substantially oxygen free atmosphere.
