Increased volumetric efficiency 4:1 Gear ratio mechanism as long as transferring torque from the input gear to the camshaft 180° of crankshaft rotation resulting in 90° of valve duration 240° of crankshaft rotation resulting in 120° of valve duration Fulcrum Rotation of no more than 24° Translational movement of rocker tower Current Timing Chain

New Components Baseplate Tappet in addition to tappet guide Fulcrum in addition to bushings Camshaft

Divide model into two portions at cam – rocker arm interface Observe de as long as mation in addition to Von Mises stresses at two distinct times: Impact position (Cam initially makes contact with rocker arm) Maximum Load position (Maximum normal as long as ce between cam in addition to rocker arm)

Impact Load: Maximum Load:

Redesign of VGC system to be located outboard of tappet guide assembly Reduce generated as long as ces by reducing separation distance, cam inertia Explore alternate 4:1 gear ratio designs Component Refinement – Redesign of high-stress components
