摘要： A novel cylinder head arrangement for an in-line four cylinder or eight cylinder engine. A modified arrangement allows additional space for installation of wider rocker arm assemblies used for variable valve lift (VVL), cylinder deactivation (CDA) and other types of variable valve actuation (VVA). In one embodiment, cam towers adjacent the end two cylinders are not used. At least one end support is used, which may be an outboard bearing on a camshaft for each end. The wider rocker assemblies may then be installed. In another embodiment, cam towers adjacent the inner two cylinders are eliminated and a single camshaft support piece with a support bearing is installed between the inner cylinders to provide support for the camshafts. The wider rocker assemblies may then be installed on at least one of the middle cylinders. A novel oil control valve operates latches in switching rocker arm assemblies.

摘要： A cover has an aperture through which an accessory gains access to the interior side of the cover and a cavity. The accessory may be any kind of sensor or actuator. To secure the accessory to the cover, an adapter coupled to the cover is provided. In one example, the adapter has a cylindrical connection section that is spin welded into place in the cavity. In another example, the adapter has self-tapping threads that engage with the surface surrounding the cavity. The adapter also has tabs extending outwardly from the cover, the tabs having a proximate section and an engagement section. The accessory has a retaining orifice that couples with the tabs in a snap-fit relationship to secure the accessory to the cover.

摘要： A valve gear for an engine includes a camshaft including a cam, a rocker shaft, and a first rocker arm which swings when pressed by the cam. The valve gear includes a spring, which biases the first rocker arm and a second rocker arm which presses an intake valve or an exhaust valve, in a return direction. The valve gear includes a first pin hole of the first rocker arm, a second pin hole and a third pin hole of the second rocker arm, a first switch pin, a second switch pin, a third switch pin, and a switch which switches between a connected state and a non-connected state of the switch pins. The second rocker arm includes a stopper against which the first rocker arm abuts. When the first rocker arm abuts against the stopper, all of the pin holes are located on the same axis.

摘要： Valve gap measuring device for measuring an axial gap between a valve seat ring of an internal combustion engine which is pressed into a blind through bore, and the base of the blind through bore, has an imaging optical system for imaging the gap at at least one circumferential location on the borehole. The imaging optical system is in image transmission connection with a digital image sensor and a digital evaluation apparatus situated downstream from the image sensor. The evaluation apparatus is configured for determining the gap width, based on the image recorded by the image sensor.

摘要： A method for setting lash on a switching rocker arm assembly includes providing a rocker arm having (i) an outer arm having a first outer side arm and a second outer side arm, the outer arm defining an opening, (ii) an inner arm disposed between the first and second outer side arms, (iii) a roller follower that selectively engages a cam, the roller follower mounted about a bearing axle that extends through the opening. A zero lash shim is inserted into a gap defined between the bearing axle and the outer arm at the opening. The rocker arm is installed into the valvetrain with the master tip cap. Lash is measured between the cam and the roller follower. The rocker arm and the master tip cap is removed. A select fit valve tip cap is installed based on the master tip cap and the measured lash.

摘要： Disclosed is a vehicle control apparatus which can execute a start-up control for improving acceleration performance at the time of starting an internal combustion engine during the running of a hybrid vehicle. When a hybrid ECU determines that a predetermined time has not yet elapsed after termination of the start-up control of the engine, and that the hybrid vehicle is in a high speed, high load condition, but not in a warming-up state, the hybrid ECU sets a value Nupest2 larger than a value Nupest1, that is usually set as a maximum value Krmx of a rise rate of an engine rotational speed.
