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.
Claims20
A turbocharger system for an engine having a cylinder block, with said turbocharger system comprising:
- a turbocharger;
- and
- a utility pedestal extending between the turbocharger and a mounting pad positioned upon the cylinder block within a valley associated with the engine, said utility pedestal comprising:
- a return oil passage having at least a portion within said pedestal and at least an uppermost part located within the cylinder block, for conveying lubricating oil from the turbocharger to the engine, with said return oil passage having a plurality of baffles.
An 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 generally planar mounting pad positioned upon said cylinder block within said valley;
- and
- a turbocharger mounted upon a utility pedestal extending between the turbocharger and the generally planar mounting pad, with said utility pedestal comprising:
- a utility pedestal mounting pad for the utility 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 utility pedestal and at least in part within the cylinder block, 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 engine, comprising:
- a cylinder block;
- a generally planar mounting pad positioned upon the cylinder block within a valley defined by cylinder heads;
- and
- an internal, isolated turbocharger oil drainback passage, located at least in part within said cylinder block and within the mounting pad, for conveying waste lubricating oil from the mounting pad to a lubrication system incorporated within the engine.
