Coolant jacket for a turbocharger oil drain

摘要

A system including a turbocharger, comprising a turbocharger bearing housing supporting a turbocharger drive shaft; an oil drain including an inlet in fluidic communication with the turbocharger bearing housing and an outlet in fluidic communication with an oil sump; and a coolant jacket enveloping the oil drain. The coolant jacket envelopes the oil drain and is positioned to provide coolant to the turbocharger bearing housing and draw heat from the oil draining through the oil drain to prevent coking of hot oil within the oil drain.
