Abstract: A multicylinder engine for a motorcycle includes a valve actuation mechanism having a hydraulically-operated valve pausing mechanism for holding at least one of an intake valve and an exhaust valve of selected cylinders in a suspended state. The valve actuation mechanism operates the intake valve and the exhaust valve, and controls flow of oil through an oil passage which introduces working oil to the valve pausing mechanism from a hydraulic-pressure control device. Air-bleeding holes are formed in the cylinder head. The air-bleeding holes are fluidly connected with portions of the oil passages that are located at a highest level in the oil passages while the motorcycle is parked in an inclined state with its side stand down.

Abstract: An improved deactivation hydraulic lash adjuster wherein the prior art lost motion spring or springs formerly located within the body of the DHLA and below the pin housing are either omitted completely or are reduced in length, spring force, and/or number and are augmented hydraulically, allowing a shorter, more compact lifter body and reduced overall lifter length. The prior art lost motion spring chamber becomes a hydraulic chamber connected to a new pressurized oil supply gallery containing an accumulator in the engine. An embodiment having no lost motion spring and solely hydraulic lost motion return can be even shorter than a spring-hydraulic hybrid because the potential hydraulic pressure to be brought against the pin housing is not a function of the length of the lost motion chamber, which length is limited only by the required displacement of the pin housing.

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: An upper surface of a head part of a valve lifter has a predetermined turn back portion at which, with a variable valve control device kept controlled to induce a maximum lift of an engine valve, a swing stroke of a rounded cam surface of a swing cam relative to the upper surface of the head part changes a traveling direction from a radially outward direction for opening the engine valve to a radially inward direction for closing the engine valve. An inlet end part of an oil hole formed in the head part is placed at a radially inside position of the upper surface other than a position where side edges of the rounded cam surface of the swing cam are in contact with the inlet end part of the oil hole when the rounded cam surface is placed in the vicinity of the turn back portion.
