Abstract

An integrated exhaust rocker arm assembly capable of selectively enabling an engine braking mode includes an inner body, an outer body, and a switchable system for selectively operatively coupling the outer body to the inner body. The inner body includes a secondary roller. The outer body includes a cam end, a valve end, and a main roller. The valve end includes a brake capsule that comprises another switchable system configured to selectively extend a plunger body to act on a valve bridge. The valve end further includes a lost motion mechanism that permits selective translation of a lost motion shaft along a lost motion receiving passage for transmitting integrated exhaust rocker arm motion to the valve bridge.
