Abstract
A greatly simplified turbocharger assembly comprised of a minimum number of parts allows accurate and efficient control of oil flow over the bearings ( ), thereby permitting excellent lubrication of the bearings with a reduced amount of oil flow through the bearing housing ( ), resulting in significantly lower hydrocarbon leakage from the turbocharger into the engine or engine exhaust, and ultimately lower hydrocarbon emissions by the engine.
