    摘要： A lubrication facilitation device is disclosed for mounting within a splash lubrication space of an engine. The device may have a rotatable engine part that has an axis of rotation about which it is configured to be rotationally disposed within a splash lubrication space of an engine. The rotatable engine part may be provided with a plurality of oil retention pockets. Each oil retention pocket may comprise an enclosure extending from a well portion to an aperture that is spaced radially away therefrom.

    摘要： An oil distribution system for an internal combustion engine comprising a longitudinal bore in the engine head or block connected to an engine oil pump. A longitudinal insert is disposed in the engine bore, the insert being formed and disposed to define segmented galleries within the bore, a first oil gallery being in communication with the engine camshaft bearings and a second oil gallery being in communication with switchable cam followers in the engine. The two galleries are separated but connected by one or more oil control valves. Thus, the camshaft bearings are exposed to high engine oil pressure at all times independent of the switchable cam followers; likewise, the switchable cam followers may be latched and unlatched at any time or condition deemed beneficial for engine operation without jeopardizing lubrication sufficiency to the camshaft bearings.

    摘要： Provided is a variable valve lift internal combustion engine including a control shaft (24) pivotally supported by a cylinder head (1) via a pivot arm (23c) pivotally supported by the cylinder head so as to able to move angularly around a rotational center line extending in parallel with an axial line of the control shaft, a power transmitting member (23a) supported by the control shaft, an actuator (21) for causing an angular movement of the control shaft around the rotational center line via the power transmitting member and a control arm (25) having a base end pivotally supported by the control shaft and a free end interposed between a cam lobe (4d) of an engine camshaft (4) and a part of a rocker arm (6). The lift of the engine valve can be varied by angularly moving the control shaft around the rotational center line and moving the base end of the control arm.
