Abstract: An apparatus for providing two features that improve fuel economy of four stroke internal combustion engines. The first is the provision of a compression ratio which is higher than normal when the engine is operating at light load; and which varies from very high at idling, down to normal at full power. This is effected by a movable piston associated with the inlet valve and connected to the throttle. The second is the provision of variable timing as well as a variable amount of opening of the inlet valve, such that at idle, the valve opens at top center of the main piston, opens only a fraction of its full lift, and closes about 70° crankshaft past top center. As the throttle is opened, the inlet valve opens farther at each open excursion to create as little flow resistance as possible to the inlet draw. At the middle of its open excursion during each valve actuation it moves in the same direction as the crankshaft enough that as the open duration becomes greater, the valve always begins to open as the main piston starts its inlet stroke, but closes later. Finally, at full power, the inlet valve begins to open slightly before the main piston comes to top center, opens fully, and closes somewhat after the main piston has reached bottom center and has started the compression stroke.

Abstract translation: 一种用于提供改善四冲程内燃机的燃料经济性的两个特征的装置。 第一个是当发动机在轻负载下运行时，提供比正常高的压缩比; 并且其在空转时非常高，在全功率下降到正常。 这通过与入口阀相关联并连接到节气门的可移动活塞来实现。 第二个是提供可变定时以及进口阀的可变量的打开，使得在怠速时，阀在主活塞的顶部中心开口，仅打开其全升程的一部分，并且关闭大约70 曲轴经过顶部中心。 当节气门打开时，入口阀在每次打开的偏移中打开得更远，从而产生尽可能少的流入阻力。 在每个阀门致动期间，在其开启偏移的中间，其沿与曲轴相同的方向运动，足以使得随着开启持续时间变大，当主活塞开始其入口冲程时，阀总是开始打开，但随后关闭。 最后，在全功率下，进气阀在主活塞到达顶部中心之前开始稍微打开，在主活塞达到底部中心并开始压缩冲程后，完全打开并稍微关闭。

Abstract: As this radial needle bearing 7c, a radial needle bearing is used which includes a cage 10b. Respective pillar portions 12, 12 which make up the cage 10b are disposed more radially inwards than a circle pitch of respective needles 8, 8. In addition, the needles 8, 8 which are adjacent to each other in a circumferential direction are caused to approach each other, so as to secure the number of such needles 8, 8. As a result, no large bending stress is applied to a tappet roller 6 without increasing the thickness of the tappet roller 6.

Abstract: A split-cycle engine includes a crankshaft rotatable about a crankshaft axis. A compression piston is slidably received within a compression cylinder and operatively connected to the crankshaft such that the compression piston reciprocates through intake and compression strokes during a single rotation of the crankshaft. An expansion piston is slidably received within an expansion cylinder and operatively connected to the crankshaft such that the expansion piston reciprocates through expansion and exhaust strokes during a single rotation of the crankshaft. A crossover passage interconnects the expansion and compression cylinders. The crossover passage includes crossover compression (XovrC) and crossover expansion (XovrE) valves defining a pressure chamber therebetween. At least one of the XovrC and XovrE valves is a balanced valve. A fluid pressure balancer biases the valve for balancing fluid pressures acting against the valve in both opening and closing directions, reducing the forces required in actuating the valve.

Abstract: A device for controlling valve movements in an internal combustion engine includes a rotating camshaft having a cam curve, the camshaft being designed, via a rocker arm, to interact with a valve mechanism for operating the inlet or exhaust valve by a valve spring. The valve mechanism includes timing gear which allows the return movement of the valve mechanism to be controlled during the closing phase of the inlet valve or exhaust valve, independently of the cam curve. A resilient element is arranged between the rocker arm and a fixed point in such a way that the rocker arm continuously follows the cam curve as the camshaft rotates. The force of the valve spring is adjusted to the moving mass of the valve mechanism and to forces counteracting the valve closure. The force exerted by the resilient element are adjusted to the mass of the rocker arm for the purpose of minimizing the energy losses of the valve mechanism. Respective central contact points between the rocker arm shaft and the rocker arm during the period when the rocker arm and the valve mechanism are separated or not separated are displaced in relation to one another in order to ensure lubrication of the rocker arm shaft.

Abstract: A rocker shaft having at least two transversely formed interior compartments is provided each of which is devised for, and capable of, containing fluid at differing pressures. A multiplicity of generally radially directed holes present along the length of the rocker shaft communicate hydraulic fluid to the compartments via passageways present in the rocker arms, or valve deactivating rocker arm sections mounted thereon. Plugs installed within the rocker shaft at locations on either side of the holes provide compartmented regions within the shaft, each region of which has the capacity to contain hydraulic fluid at different pressures. The rocker shaft is capped at each end. Hydraulic fluid may be provided to the rocker shaft interior in a number of ways, such as through additional holes aligned with passageways provided in the cylinder head or through clearance openings between rocker shaft fasteners and rocker shaft mounting holes.

Abstract: An internal combustion engine includes a throttle controlling mechanism; a valve characteristic varying mechanism which controls an internal EGR rate by the control of an overlap period Pa and a non-overlap period Pb; and an output setting means which sets a required amount of engine output. The throttle controlling mechanism controls an opening degree of a throttle valve to fully open the throttle valve at a predetermined load Da with an increase in an operating amount D in a first load range Fa which covers load range below the predetermined load Da in a low-load range, and to keeps the throttle valve fully opened in a second load range Fb which covers a load range over the predetermined load Da. The valve characteristic varying mechanism controls the engine output by controlling the overlap period Pa or the non-overlap period Pb according to the required amount D over the entire load range, and controls valve operation characteristics to obtain a maximum internal EGR rate at the predetermined load Da.

Abstract: A deactivating rocker arm mechanical adjustment system for internal combustion engines is provided wherein a lash adjustment screw which has eccentric cam and a feature by which the screw can be rotated using a tool. The adjustment screw is installed a valve actuation section of a split rocker arm wherein the cam end of the adjustment screw engages a feature of the cam follower section of the split rocker arm. When the lash adjustment screw is rotated, the design of the cam is such that the angular orientation of the valve actuation and cam follower sections is varied and in turn varies the distance or lash between the cam follower section latch pin and the receiving latch pin hole in the valve actuation section. The lash adjustment screw is rotated until a previously specified lash is obtained and then a jam nut is tightened to prevent rotation of the lash adjustment screw. Valvetrain component design may be altered that other than threaded means may be used to control the rotational orientation of the adjustment cam. An additional feature of the invention is that in the preferred embodiment, the lash adjustment screw provides a valve actuation section feature upon which a lost motion spring is mounted.
