Abstract
A valve train assembly () includes a fuel injector (), an intake rocker lever assembly (), and an exhaust rocker lever assembly (). The intake and exhaust rocker lever assemblies () can include an eccentric hydraulic lash adjuster () that is located in the nose () of the respective rocker lever assemblies (). The rocker lever assemblies () are configured to allow a clearance area between a nose () of the intake rocker lever assembly () and the nose () of the exhaust rocker lever assembly (). As such, the fuel injector () can be positioned in the clearance area, while still allowing the eccentric hydraulic lash adjusters to apply a load onto a corresponding valve bridge (). For example, the eccentric hydraulic lash adjuster () can include an outer housing () and a pivot ball (), wherein the pivot ball () is positioned at an offset () from a lateral centerline of the outer housing ().
