摘要： A fuel injection valve has: a tubular body, a valve seat member, a valve body, a core tube, a bias spring, and an electromagnetic actuator. The core tube is press fitted into the tubular body. The core tube has a first end side opposing an absorption section of the valve body in such a manner as to form an axial gap interposed between the first end side of the core tube and the absorption section. The core tube has a second end side axially extending in the tubular body to a certain position on a way to the second end side of the tubular body. The axially extending second end side of the core tube has an outer periphery which is formed with a reduced diameter section for increasing an accuracy in positioning the core tube when the core tube is press fitted into the tubular body.

摘要： A valve timing control device includes a drive pulley driven by a crankshaft of an engine, and a driven camshaft. The camshaft has a cam that serves to open and close an intake port. An engine valve is spring-loaded by a valve spring, whereas the cam opens or closes the engine valve against the bias of the spring. Torque is transmittable between the drive pulley and the camshaft, and a rotation angle adjusting mechanism is provided therebetween. The rotation angle adjusting mechanism has a movable operating member being movable in a radial direction.

摘要： Before starting an air-fuel ratio feedback control utilizing an air-fuel ratio sensor, activation of a wide-range air-fuel ratio sensor in an internal combustion engine is diagnosed by calculating heat transferred to and from the air-fuel ratio sensor whose output value varies in response to oxygen concentration in exhaust which varies according to the air-fuel ratio of an intake air-fuel mixture of the internal combustion engine, and estimating the activation time from the starting of the engine until the air-fuel ratio sensor is activated, based on said calculated result of the heat transfer. Alternatively, activation of the sensor is diagnosed under the condition that an output voltage of the oxygen concentration detecting unit of the sensor is fixed to a value either equal to or above a rich-side set voltage or equal to or under a lean-side set voltage, before starting the air-fuel ratio feedback control.

摘要： Cylinder judgment signals are output from a plurality of cam sensors at every uneven crank angle interval. The number of cylinder judgment signals output from one cam sensor during a time of period between a previous output and a present output of cylinder judgment signals from the other cam sensor, is counted up, to judge a specific cylinder based on the number of outputs, so that cylinders other than the specific cylinder are judged based on the judgment result and the cylinder judgment signals, and at the same time, each time the cylinder is judged by the above method, a period of from the previous cylinder judgment to the present cylinder judgment is calculated, to judge erroneous detection of cylinder judgment signal due to noise based on a ratio between a previous calculation value and a present calculation value of the period, and when the erroneous detection is judged, the cylinder judgment result based on the cylinder judgment signals is canceled.

摘要： A controller that outputs control signals to an actuator of a variable valve timing mechanism is integrally equipped with a cam sensor that takes out from a camshaft signals for discriminating a cylinder corresponding to a reference piston position. The controller discriminates the cylinder corresponding to the reference piston position, computes a rotation phase of the camshaft relative to a crankshaft, and transmits the result of the cylinder discrimination process to an engine controller.
