摘要： A spark plug that prevents a decrease in strength of a member to which a mark is attached while ensuring a readability of the mark, and a method of manufacturing the spark plug. The spark plug is configured to ignite an air-fuel mixture in an internal combustion engine. The spark plug includes: a mark formed of an oxide film generated on a surface of a metallic member or is formed of the metallic member and the oxide film; and a coating material covering the whole mark and allowing transmission of light.

摘要： A method to determine reference actuator positions for a gasoline engine, includes entering a base torque request, a known spark advance, a known CAM position and a known exhaust gas recirculation (EGR) valve position into an inverse torque model to generate a first iteration desired air per cylinder (APC) value. The first iteration desired APC value is passed through a deadband filter to produce a filtered first iteration desired APC signal. A Predicted As Cal (PAC) spark advance is calculated for the filtered first iteration desired APC value. The PAC spark advance and the base torque request are modified, and data from a first lookup table is entered to generate a second iteration desired APC value.

摘要： A spark plug and a method of manufacturing the same, where the spark plug has a metal shell, an insulator, a center electrode, a ground electrode, and a gasket located over a threaded portion of the shell and used to seal the spark plug against a cylinder head. Once the gasket is attached on the spark plug, it is shrunk to become a post-formed gasket with an inner diameter that prevents the post-formed gasket from slipping over a threaded portion of the metallic shell. This process may be carried out with a collet type machine that produces a post-formed gasket that is flat and has a substantially uniform thickness, which can improve the sealability of the gasket. This may be important when the spark plug is installed in a cylinder head made from a lost foam casting process or other process that creates a somewhat porous sealing surface.

摘要： A sparkplug including an induction coil and an electrode. The induction coil includes two end portions, the electrode extending in a continuation of one of the two end portions. The induction coil includes a conducting wire wound to form a succession of turns, the one of the two end portions having a terminal turn connected to the electrode. The one of the two end portions includes a plurality of coaxial end turns that extend between the terminal turn and an upstream turn, and the terminal turn has a diameter smaller than the diameter of the upstream turn so to reduce strength of the electric field induced in the one of said two end portions near the terminal turn.

摘要： A spark plug (20) includes an insulator seat angle (αi) of 35° to 50° and an increased insulator thickness (ti) in selected areas around the insulator seat (28). The insulator seat angle (αi) is greater than or equal to a boundary value provided by the equation: 90°−a cos [1−(R1−R2)÷(R4+R5)], and preferably not greater than 150% of the boundary value. The radii (R1, R2, R3, R4, R5) can be adjusted to maximize R4 while maintaining an acceptable R2. A gasket is compressed between the insulator (22) and shell (58), and the inner gasket thickness (tg2) is greater than or equal to 70% of the outer gasket thickness (tg1).

摘要： An ignition device for an internal combustion engine and method of construction therefore includes a housing with an insulator secured therein. A center electrode is mounted within the insulator. A ground electrode extends from the housing with a portion of the ground electrode defining a spark gap across from the center electrode. The center electrode has a firing tip, wherein a resistance weld joint initially bonds the firing tip to the center electrode and a continuous bead of overlapping first weld pools formed substantially from the material of the firing tip further bonds the firing tip to the electrode. A continuous bead of overlapping second weld pools formed radially outwardly from the first weld pools forms a rounded shoulder surface extending from the first weld pools to an outer surface of the center electrode.
