  • Turbocharger bearing lubrication system
    Patent number: 6709160
    Abstract: A greatly simplified turbocharger assembly comprised of a minimum number of parts allows accurate and efficient control of oil flow over the bearings (44,46), thereby permitting excellent lubrication of the bearings with a reduced amount of oil flow through the bearing housing (16), resulting in significantly lower hydrocarbon leakage from the turbocharger into the engine or engine exhaust, and ultimately lower hydrocarbon emissions by the engine.
