Abstract
A turbocharger system for an internal combustion engine includes a turbocharger with a utility pedestal extending between the turbocharger and the hard point associated with the cylinder block. The utility pedestal includes a mounting pad for attaching the combined turbocharger and pedestal assembly to an engine, as well as oil and coolant supply passages for supplying the turbocharger with coolant and lubricating oil under pressure. An internal, isolated, turbocharger oil drainback passage conducts waste oil from the turbocharger to a crankcase sump without permitting the waste oil to contact the engine's moving parts.
Claims12
A turbocharger system for an internal combustion engine having a cylinder block, with said turbocharger system comprising:
- a turbocharger;
- and
- a utility pedestal extending between the turbocharger and a mounting point associated with the engine, with said utility pedestal comprising:
- a mounting pad for the pedestal;
- an oil supply passage for conveying lubricating oil under pressure from the engine to the turbocharger;
- and
- a return oil passage, contained at least in part within said pedestal, for conveying lubricating oil from the turbocharger to a lubrication system incorporated within the engine, with said return oil passage being routed such that contact between waste oil flowing from said turbocharger and moving parts of the engine is minimized prior to de-aeration of the waste oil.
An internal combustion engine, comprising:
- a V-block configured cylinder block;
- a plurality of cylinder heads attached to said cylinder block, with said cylinder heads and said cylinder block defining a valley between the cylinder heads;
- a turbocharger mounting pad configured upon said cylinder block within said valley;
- and
- a turbocharger mounted upon a utility pedestal extending between the turbocharger and a hard point associated with the cylinder block, with said utility pedestal comprising:
- a mounting pad for the pedestal;
- an oil supply passage for conveying lubricating oil under pressure from the cylinder block to the turbocharger;
- an internal, isolated turbocharger oil drainback passage, located at least in part within said pedestal, for conveying waste lubricating oil from the turbocharger to a lubrication system incorporated within the engine, with said drainback passage being routed such that contact between waste oil flowing from said turbocharger and moving parts of the engine is minimized prior to de-aeration of the waste oil.
An internal combustion engine, comprising:
- a cylinder block;
- a turbocharger mounting pad configured upon said cylinder block;
- and
- an internal, isolated turbocharger oil drainback passage, located at least in part within said cylinder block, for conveying waste lubricating oil from said turbocharger mounting pad to a lubrication system incorporated within the engine, with said drainback passage being routed such that contact between said waste oil and moving parts of the engine is minimized prior to de-aeration of the waste oil.
