    Abstract: A cam element portions is configured such that respective maximum lift portions (lift ending points) of both-side end-face cams thereof are provided at respective phases which are different from each other in a rotational direction and that a maximum value of a length, in an axial direction, between respective cam faces of the both-side end-face cams which are provided at the same phase is set to be a distance, in the axial direction, between a first operational member and a second operational member or smaller. Accordingly, in a valve gear of an engine in which cams operative to control opening/closing of a valve are switchable, it can be properly prevented that a camshaft locks and stop rotating because of an operational malfunction of an operational member or the like.

    Abstract: An adjustable valve device includes: a first cam portion penetrated by a camshaft, rotating with the camshaft, and including an elongated hole formed therein; a U or L shaped second cam portion supported by the first cam portion so as to swing to move between a first state and a second state; a stopper pin fixed to the second cam portion and penetrating through the elongated hole; a biasing member biasing the stopper pin so that the second cam portion becomes in the first state; a lock mechanism locking the second cam portion only when the second cam portion is in the first state; and a cam follower exerting a reactive force so that the second cam portion becomes in the second state in a state where a lock of the second cam portion is released, wherein the reactive force is greater than a biasing force of the biasing member.

    Abstract: A variable valve lift apparatus of an engine includes a first body rotated at within a preset angle range by rotating a high-speed cam coupled to a camshaft, a second body coupled to the first body or decoupled from the first body and rotated within a preset angle range by rotating a low-cam coupled to the camshaft when the second body is decoupled from the first body, a latching pin provided retractably forward of the first body such that the first body is coupled to or decoupled from the second body, and an actuating unit to retractably actuate the latching pin. The degree of the lift of the valve is variably controlled in two stages of high-speed and low-speed modes through the rotary motion of the high speed cam or low speed cam by coupling or decoupling the first and second bodies to or from each other.

    Abstract: An overhead-camshaft internal combustion engine is disclosed, in which the fuel pumps are arranged to use efficiently the space within a cylinder head assembly of the engine. The cylinder head assembly includes a cylinder head block, and the engine comprises a camshaft rotatable about a camshaft axis and having a plurality of inlet and exhaust cams for actuating associated inlet and exhaust valves of the engine, and at least one fuel pump comprising a unit pump assembly driven directly by a respective pump cam provided on the camshaft. The engine further comprises a plurality of rocker arms driven by the inlet and exhaust cams and arranged to actuate the inlet and exhaust valves. Each rocker arm is pivotable about a rocker arm axis which is substantially parallel to the camshaft axis. The or each pump assembly is mounted between the rocker arm axis and the cylinder head block.

    Abstract: An engine valve actuation mechanism for producing a variable engine valve event includes a cam, a rocker arm, a rocker arm shaft, an eccentric rocker arm bushing, and a bushing actuation device. The eccentric rocker arm bushing is disposed in an axial hole in the rocker arm, the rocker arm shaft being disposed in the eccentric rocker arm bushing with the rocker arm shaft and the eccentric rocker arm bushing having offset axial centerlines. One end of the rocker arm and the cam is connected to form a kinematic pair and the other end of the rocker arm is located above the engine valve with a gap between the cam and the engine valve. The bushing actuation device is placed in the rocker arm and drives the eccentric rocker arm bushing to rotate, and the rotation of the eccentric rocker arm bushing changes the gap to generate the variable engine valve event.
