Abstract: A drive device for vehicles includes a transmission device including a transmission mechanism that changes a speed of inputted rotation of a drive source of a vehicle and outputs the rotation and that is provided on an axis of rotation orthogonal to a front-rear direction of the vehicle; and a casing that holds the transmission mechanism; and a control device that performs electronic control of the transmission device, at least a part of the control device being installed on an outside of the casing, and the control device is installed at either one of a front side portion and a rear side portion of the casing in the front-rear direction of the vehicle.

Abstract: An integrated ignition and electronic auto-choke module for an internal combustion engine and an internal combustion engine including the same. In one aspect, the module includes a housing that is configured to be mounted to an engine block of an internal combustion engine. The housing may contain at least a portion of a first temperature sensor that measures a first temperature indicative of an engine temperature. The housing may also contain a controller and at least a portion of an ignition circuit. The controller may be coupled to the first temperature sensor and configured to determine a starting position of a choke valve based on the first temperature and operate an actuator to move the choke valve into the starting position accordingly.

Abstract: A non-resonant knock sensor includes: a sensor body having a metal shell provided with a shell-side cylindrical portion and a shell-side flange portion, a piezoelectric element, a weight arranged to hold the piezoelectric element between the shell-side flange portion and the weight and a fixing member having a third through hole through which the shell-side cylindrical portion is inserted and being arranged to press the weight toward the shell-side flange portion and thereby fix the weight in position; and a resin molded part. The fixing member has formed therein flow paths for introducing a resin into an inner space between the shell-side cylindrical portion and the piezoelectric element. The flow paths are provided in the form of at least one of being connected to the third through hole and being separated from the third through hole and are formed intermittently in a circumferential direction of the fixing member.

Abstract: A fuel injection device (fuel supply system) of a common rail type fuel injection system for an engine includes a pressure sensor disposed in a fuel inlet of an injector for measuring a fuel pressure at a position where the sensor is disposed and an ECU for sensing various kinds of pressure fluctuations associated with the injection including a pressure leak due to an injection operation of the injector and waving characteristics due to actual injection thereof based on sensor outputs from the pressure sensor. The ECU serially obtains the sensor outputs from the pressure sensor at intervals of 20 ?sec.

Abstract: The arrangement for mounting a sparkplug of an internal combustion engine includes mounting the sparkplug so that all of the outside electrodes are arranged at an intake port side area and/or an exhaust port side area. Alternatively, in the case where at least one of the outside electrodes is located outside of the above-mentioned areas, no other remaining outside electrodes are arranged at a position that faces that outside electrode across the central electrode.

Abstract: A mounting fixture for an engine knock sensor is provided. The fixture includes a base and a support member. The support member is joined to the base with a press fit joint. The base includes an aperture and the support member is inserted in the aperture. The support member can be a bolt or a sleeve. The invention can also include a lip, associated with the support member for retaining a spring washer. The spring washer can be deflected between the support member and a knock sensor component for pressing the knock sensor component against the base.
