Abstract

A valvetrain for a type II engine comprises a valve bridge, a switching rocker arm, a center capsule, a first auxiliary rocker arm, and a first auxiliary capsule. The selectively switching rocker arm is configured to switch configurations to transfer a first valve actuation profile from a first overhead cam lobe to the valve bridge center point and to transfer a second valve actuation profile from a second overhead cam lobe to the center point. The center capsule is configured to switch between an active state and a lost motion state. The first auxiliary rocker arm is configured to transfer a first auxiliary valve actuation profile from a third overhead cam lobe to the valve bridge first valve mounting area. The valvetrain can further comprise a second auxiliary rocker arm and a second auxiliary capsule.
