Abstract: A rocker arm assembly for a Type II valvetrain arranged for cooperation with a cylinder head includes a roller finger follower (RFF) and a lost motion with reset (LMR) hydraulic assembly. The RFF has a first end and a second end. The first end cooperates with a valve. The LMR hydraulic assembly has a hydraulic control element and a plunger. The LMR hydraulic assembly moves the plunger between a rigid position and a non-rigid position. The LMR hydraulic assembly is configured at the second end of the RFF.

Abstract: A method of providing a rocker arm set for a valvetrain includes providing a first intake rocker arm, a second intake rocker arm and a first exhaust rocker arm. The first intake rocker arm is configured as a switching rocker arm for a first intake valve on a first cylinder. The second intake rocker arm is for a second intake valve on a second cylinder. The second rocker arm is configured to operate in a normal Otto cycle mode. The first exhaust rocker arm is provided for a first exhaust valve on the second cylinder. The first intake rocker arm operates in one of an LIVC or EIVC mode where the first intake rocker arm is configured to open or close at a different time compared to the second intake valve. The first exhaust rocker arm operates in a cylinder deactivation mode.
