摘要： An internal combustion engine includes an engine block, a piston, a cylinder head, and a valve train. The engine block includes a cylinder block including a cylinder bore and a crankcase defining a crankcase chamber with a crankshaft positioned within the crankcase chamber. The piston is coupled to the crankshaft and configured to reciprocate within the cylinder bore. The cylinder head is coupled to the cylinder block. The valve train includes a camshaft, a first and second pushrod, a first and second rocker arm, an exhaust valve housed, and an intake valve. The first rocker arm, the second rocker arm, the exhaust valve, and the intake valve each include at least a layer of a low friction material. The first and second pushrod each pass through a pushrod seal to prevent fluid from reaching the rocker chamber to fluidly isolate the rocker chamber from the crankcase chamber.

摘要： A valvetrain system for primary mode and auxiliary mode variable valve actuation, comprising a primary rocker arm, a rotatable cam shaft, a valve bridge, and a switchable capsule. The rotatable cam shaft is configured for variably transferring forces directly or indirectly to the primary rocker arm to rock the primary rocker arm according to a primary mode valve actuation profile. The valve bridge comprises a primary arm comprising a primary valve mounting area and a pass- through. An auxiliary valve mount is configured to transfer an auxiliary mode valve actuation profile through the pass-through. A switchable capsule comprises a movable element. The movable element is switchable between an extended position and a collapsed position. The switchable capsule is configured to actuate on the auxiliary valve mount to impart the auxiliary mode valve actuation profile to the auxiliary valve when the movable element is in the extended position.

摘要： An internal combustion engine has a valvetrain that includes a rocker arm assembly on which is mounted an electronic device and at least a part of a generator. The generator converts some of the mechanical energy that is transmitted through the rocker arm assemblies into electricity. That electricity may be used to power an electric latch, a transmitter, or another type of rocker arm assembly-mounted electrical device. Various generator configurations are described. In some configurations, the generator is piezoelectric. In other configurations, the generator is electromagnetic. In some configurations, the generator is driven by force transmitted by the rocker arm assembly from a cam. In some configurations, the generator is driven by vibrations.

摘要： A decompression assembly (12) and method can include a linkage mechanism (20), a biasing assembly (38) for normally biasing the linkage mechanism toward a locked position when an internal combustion engine (10) is in an unpowered state, and an actuating piston (44) for driving the linkage mechanism from the locked position toward the unlocked position when the engine (10) is in a powered state. The engine can include a cam lobe (70) for driving pivotal oscillation of a rocker arm (36) engageable with a valve (16) in the engine for movement between open and closed positions. The linkage mechanism allows a full range of movement of the rocker arm when in an unlocked position, and restricts movement of the rocker arm to less than a full range of movement when the linkage mechanism is in a locked position for maintaining the valve in a partially open position.

摘要： A valve operating system includes a cam and a roller follower. An input piston is spring-biased to follow motion of the roller follower. A hydraulic chamber filled with fluid selectively transfers motion from the input piston to an output piston operatively engaged with a poppet valve. A variable -bleed valve is in fluid communication with the hydraulic chamber and an outlet channel and configured to selectively vary a bleed rate between the hydraulic chamber and outlet channel. Displacement of the input piston into the hydraulic chamber causes movement of the output piston, depending on the bleed rate. A pushrod may transfer motion from the roller follower to the input piston. A hydraulic damping shoulder may restrict the closing velocity of the output piston. The system may be further characterized by an absence of a rocker arm. An auxiliary piston may replace the variable-bleed orifice in the lost-motion hydraulic linkage.
摘要翻译：阀操作系统包括凸轮和滚子从动件。输入活塞被弹簧偏置以跟随滚子从动件的运动。填充有流体的液压室选择性地将运动从输入活塞传递到与提升阀可操作地接合的输出活塞。可变偏心阀与液压室和出口通道流体连通并且被配置为选择性地改变液压室和出口通道之间的排出速率。输入活塞进入液压室的位移导致输出活塞的运动，这取决于排放速率。推杆可以将运动从滚子从动件传递到输入活塞。液压阻尼肩可能会限制输出活塞的关闭速度。该系统的进一步特征在于没有摇臂。辅助活塞可以代替失速液压联动装置中的可变排放口。

摘要： A locking mechanism for a plural rocker arm valve train assembly is provided. The locking mechanism is adapted for use with a camshaft having a plurality of different cam lobes having a plurality of different profiles, which result in variable valve displacement and duration. A plurality of rocker arms are located on a pivot shaft which runs parallel to the camshaft, each rocker arm having structures configured to be acted upon by respective lobes of the camshaft. An active rocker arm has structure configured to act upon an engine valve or valves. A movable locking element is fully enclosed by the rocker arms and is capable of selectively moving along the pivot shaft to allow the active rocker arm to selectively engage one or more of the other rocker arms for common pivoting, resulting in varied displacement of the engine valve or valves.

The upper rocker arm is in contact with the cam at one end and is nested on a push rod for valve wherein the valve-driving device further includes a shaft for lower rocker arm between the upper rocker arm and the cylinder head,a lower rocker arm fitted on the shaft for lower rocker arm, and a concave wheel fitted on the camshaft,the lower rocker arm being in contact with the concave wheel at one end, being nested on the push rod for valve at the other end and can slide freely on the push rod. There is a segment of contacting face between the upper rocker arm and the lower rocker arm, and the upper rocker arm and the lower rocker arm can be turned in the same direction by the interaction between the contacting faces.
