Embodiment Construction

[0020] will now first refer to figure 2 , Figure 3A , Figure 3B , Figure 3C and Figure 4 Example valve bridges and actuation systems are described in accordance with aspects of the present disclosure. The directional terms "longitudinal", "transverse" and "vertical" will be used herein and are defined by Figure 3A Orthogonal axes "L", "T" and "V" in represent. The valve actuation system 100 may include a valve bridge 200, and the valve bridge 200 may include a main event rocker interface portion 210 for receiving motion from a main event rocker 110, the main event rocker 110 is connected with the auxiliary event rocker 110 as an auxiliary The auxiliary rocker 140 of the motion source together may be mounted for pivotal movement on the rocker axis 112 . As an alternative to the auxiliary rocker 140, the auxiliary motion source may comprise, for example, a master / slave hydraulic system. The first valve interface portion 220 and the second valve interface portion 240 ...

Abstract

A system for actuating engine valves may include a valve bridge having a main event rocker interface portion, a first valve interface portion and a second valve interface portion extending in generally opposite directions from the main event rocker interface portion. The second valve interface portion may include an open end including a slot for receiving a bridge pin. The slot permits the valve bridge to be removed from the actuation system without removal of the main event rocker or other actuating components, such as an auxiliary rocker. The valve bridge can be removed from the valve trainwithout requiring removal of other actuation system components, such as auxiliary rockers or main event rockers. A single valve bridge configuration can be used with different valve spans, which may occur among different cylinder sizes in a given engine family, or across different engine families.

Description

technical field [0001] The present disclosure generally relates to valve actuation system components and valve actuation systems used in internal combustion engines. Background technique [0002] Internal combustion engines generally include a plurality of valves for cyclically controlling the entry and exit of combustion components from a combustion chamber, usually defined by a movable piston and cylinder arrangement. In addition to intake and exhaust valves, auxiliary valves may be provided to support auxiliary valve events associated with different respective engine functions. Each cylinder of the engine may include multiple intake valves, multiple exhaust valves, and multiple secondary valves. Cam and rocker elements actuate and control valve position to achieve desired engine functions. Additionally, the prior art includes actuation systems for controlling and actuating each of a plurality of valves differently to achieve different engine power goals. These power go...
