摘要： PROBLEM TO BE SOLVED: To provide a variable valve train facilitating shim attaching/detaching work by positively preventing the fall of a shim for absorbing a clearance between a reference wall part and a body of a valve characteristic adjusting mechanism of an internal combustion engine.
SOLUTION: A space Da between inner surfaces 164d of the shim 164 is larger than a width Dc between retreat faces 130c, so that a sufficient allowance can be provided between the retreat faces 130c and the shim 164 to facilitate attaching/detaching work to/from a rocker shaft 130 when selecting the shim 164. Since the space Da between the inner surfaces 164d is smaller than a diameter Db of a base outer peripheral surface 130d of the rocker shaft 130, the shim 164 is prevented from falling from the rocker shaft 130 because the shim 164 does not rotate large. Further, the retreat faces 130c extend into the internal space of swing cams 124, 126, positive pressure or negative pressure of gas and liquid generated in the swing cams 124, 126 can be easily discharged to the outside of an intermediate drive mechanism 120. The valve characteristic adjustment can thereby be made with little energy.

摘要翻译：要解决的问题：通过积极地防止用于吸收内部燃烧的阀特性调节机构的参考壁部分和主体之间的间隙的垫片的下降来提供便于垫片附接/拆卸工作的可变气门机构发动机。解决方案：垫片164的内表面164d之间的空间Da大于后退面130c之间的宽度Dc，使得在退回面130c和垫片164之间可以提供足够的余量以便于附接/分离工作当选择垫片164时，与摇臂轴130相对/从摇臂轴130移动。由于内表面164d之间的空间Da小于摇臂轴130的基底外周表面130d的直径Db，因此防止了垫片164从摇摆轴130因为垫片164不旋转大。此外，后退面130c延伸到摆动凸轮124,126的内部空间中，在旋转凸轮124,126中产生的气体和液体的正压力或负压可以容易地排出到中间驱动机构120的外部。因此能够以很少的能量进行阀门特性调整。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To further reduce the number of part items, by omitting a pin, while securing the same function as the pin separate from a control shaft.
SOLUTION: This valve train drives a valve for opening and closing by transmitting rotation of an intake camshaft to the intake valve by a slider 48; and changes a valve characteristic of the intake valve by being displaced in the shaft direction while rotating the slider 48, by transmitting the movement in the shaft direction of the control shaft 36 to the slider 48 via an engaging projection part 35 and a peripheral groove 49. In this valve train, a guide groove 55 for connecting an end surface 48D of the slider 48 and the peripheral groove 49 in the shaft direction, is arranged on an inner wall of the slider 48. The engaging projection part 35 is introduced to the peripheral groove 49 via the guide groove 55 from an external part of the slider 48, and is engaged in a place different from a connecting part with the guide groove 55 of the peripheral groove 49 by relatively rotating the control shaft 36 and the slider 48 in this state.

摘要： PROBLEM TO BE SOLVED: To provide a variable valve train materializing valve characteristics independent for each cylinder group and easily arranged on a cylinder head of a multi-cylinder internal combustion engine. SOLUTION: Two control shafts 131, 132 corresponding to number of cylinder groups exist in parallel at a rocking center part common for all intermediate drive mechanism. The two control shafts 131, 132 can exist for each control shaft without interference even if the all intermediate drive mechanism arrange on a same shaft. Each control shaft can be driven independently in an axial direction to materialize valve characteristics different for each cylinder group. Consequently, combustion conditions in #2, #3 cylinders and in #1, #4 cylinders can be independently adjusted without relying on a throttle valve and expansion of installation space can be suppressed. In a case of reduced cylinder process, valve lift of the cylinder group of objective of reduced cylinder can be made "0" and fuel economy can be improved further. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：为每个气缸组提供独立于可容易地设置在多缸内燃机的气缸盖上的可变气门机构实现阀特性。解决方案：对应于气缸组数量的两个控制轴131,132平行于所有中间驱动机构共用的摆动中心部分。即使全部中间驱动机构设置在相同的轴上，两个控制轴131,132也可以不受干扰地存在于每个控制轴上。每个控制轴可以在轴向独立地驱动，以实现每个气缸组不同的阀门特性。因此，可以独立地调节＃2，＃3气缸和＃1，＃4气缸中的燃烧条件，而不依赖于节流阀，并且可以抑制安装空间的扩大。在减缸运行的情况下，气缸组减缸的气门升程可以为“0”，进一步提高燃油经济性。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To reduce friction more than a case in which a rotating energization force by a lost motion device is set constant while securely pressing a cam input part against a cam. SOLUTION: An acting angle variable mechanism 33 transmits the rotation of an intake cam 24 to an input arm 38 through a cam input part to swing the arm 38 and opens an intake valve 21 against a valve spring 23 by an output arm 39 swung in association with the input arm 38. The acting angle of the intake cam 24 is changed by changing a relative phase difference between input/output arms 38 and 39 in the swing direction. The lost motion device 55 presses the cam input part against the intake cam 24 by rotatingly energizing the input arm 38 in the reverse direction of the swing direction of the input arm 38 by the intake cam 24. Also, in an area specified by the acting angle, a rotating energizing force by the lost motion device 55 is reduced in an area where the acting angle is large less than that in an area where the acting angle is small.

摘要： PROBLEM TO BE SOLVED: To accurately measure a valve lift quantity; and to prevent complication of a valve system, when measuring the valve lift quantity for adjusting a variable valve system. SOLUTION: A screw thread 41 for screwing in a nut 40 is formed in a part exposed from a body 31 when supplying oil to a rash adjuster 22 when operating an engine in an outer peripheral surface of a plunger 36 of the rash adjuster 22. Immersion in the body 31 of the plunger 36 for accurately measuring the valve lift quantity, can be prohibited even if the engine is not operated by abutting on the body 31 by fastening this nut 40. Since such prohibition of immersion in the body 31 of the plunger 36 can be realized by a simple constitution for arranging the screw thread 41 on the outer peripheral surface of its plunger 36, complication of the valve system can be restrained.

摘要翻译：要解决的问题：准确测量气门升程量; 并且当测量用于调节可变阀系统的气门升程量时，防止阀门系统的复杂化。解决方案：当在皮疹调节器的柱塞36的外周表面中操作发动机时，将螺母40拧入螺纹40的螺纹41形成在从主体31露出的部分中，当向皮疹调节器22供油时即使发动机通过紧固该螺母40而碰撞在主体31上而不能进行操作，也可以禁止浸入活塞36的主体31中以精确地测量气门升程量。由于这种禁止浸入主体31 可以通过将螺纹41布置在其柱塞36的外周面上的简单结构来实现，因此可以抑制阀系统的复杂化。版权所有（C）2006，JPO＆NCIPI

The non-lift zone for the oscillation arm 18a is shorter than the non-lift zone for the oscillation arm 18b.

摘要： PROBLEM TO BE SOLVED: To provide a valve characteristic control device for an internal combustion engine capable of favorably controlling a change in an engine operation status such as engine output and engine rotation speed apt to occur when forcibly driving a variable valve system.
SOLUTION: An electronic control device 7 executes drive control of a variable valve system 3 capable of varying a valve characteristic of an intake valve 21. The electronic control device 7 judges that an abnormality is present in the variable valve system 3 when the deviation of an actual valve characteristic from a target valve characteristic set on the basis of an engine operation status exceeds a reference value and the status exceeding the reference value continues for a predetermined time. When the judgment on the presence of abnormity is made, the variable valve system 3 is forcibly driven. In the forcible drive, the electronic control device 7 forcibly drives the variable valve system 3 on the condition that a throttle valve 17 provided in an intake pipe 1PI of the engine 1 is closed.

摘要： PROBLEM TO BE SOLVED: To provide a variable valve train exerting control of valve characteristics with high precision by constituting so as to maintain the strength of a control shaft for regulating the valve characteristics. SOLUTION: Each engaging part 132c to be engaged with a slider gear is made of an iron based material, and each coupling shaft 132d is made of an aluminum alloy material same as that of a cylinder head. Thus, coefficient of thermal expansion of the control shaft 132 can be more approximated to that of the cylinder head than that in the case of constituting the entire control shaft 132 of an iron-based material. Consequently, even in the case of change in ambient temperature, displacement of the position of the engaging part 132c relative to the cylinder head is restrained. The strength of the engaging part 132c is adequately maintained by the use of the iron-based material in the engaging part 132c, and deformation of the control shaft 132 can be prevented.
