Abstract (en)
[origin: WO2021226636A1] A valve bridge system comprises a valve bridge body configured to extend between at least two engine valves of an internal combustion engine. The valve bridge body comprises a through-bore configured to align with a first engine valve and to receive a bridge pin. A bridge pin boss has the through-bore formed therein, has a longitudinal length and terminates in an upper surface. The longitudinal length is configured such that the upper surface of the bridge pin boss contacts a surface of the auxiliary rocker arm to resist uncontrolled movement of the valve bridge when the valve bridge is in an uncontrolled state relative to the at least two engine valves.
