Abstract
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.
Claims19
A method, comprising:
- supplying oil to a turbocharger from an engine block of a V engine with inbound exhaust conduits, the turbocharger positioned between banks of the V engine;
- draining oil from the turbocharger back to the engine block via an oil drain extending from the turbocharger to an oil sump;
- and
- directing coolant from the V engine to the turbocharger, through a coolant jacket located peripherally around a region of the oil drain external to a turbocharger housing,
- wherein the coolant jacket is coaxial with the region of the oil drain external to the turbocharger housing.
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 circumferentially enveloping an outside of the oil drain in a region of the oil drain exterior to the turbocharger,
- wherein a direction of a flow of coolant within the coolant jacket is counter to a direction of flow of oil through the oil drain.
A system for a turbocharger, comprising:
- a pressure fed oil inlet providing oil to the turbocharger;
- an oil drain to drain the oil from the turbocharger;
- and
- a coolant jacket located around a circumference of an outside of the oil drain at a region of the oil drain located exterior to the turbocharger
- wherein the region of the oil drain located exterior to the turbocharger housing extends along an entire length of the oil drain between a turbocharger housing and an oil sump within an engine block.
