Abstract
A turbocharger system for an internal combustion engine includes a turbocharger with a utility pedestal extending between the turbocharger and 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 internal oil and coolant supply passages for supplying the turbocharger with coolant and lubricating oil under pressure.
Claims20
A turbocharger system for an engine having a cylinder block, comprising:
- a turbocharger;
- and
- a utility pedestal fastened to the turbocharger and mounted to a hard point that extends laterally between opposing cylinder banks and is located on a mid-portion of the cylinder block, with said utility pedestal comprising:
- a mounting pad located at a lower extremity of the pedestal for mounting the pedestal to the hard point;
- an internal oil supply passage for conveying lubricating oil under pressure, from an internal lubrication passage in the cylinder block through the hard point, to the turbocharger;
- and
- an internal coolant supply passage for conveying coolant under pressure, from an internal coolant passage in the cylinder block through the hard point, to the turbocharger.
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 hard point configured upon said cylinder block within said valley, with said hard point comprising a plurality of ported bosses for furnishing lubricating oil and coolant to a turbocharger, the hard point extending laterally between opposing cylinder heads of the cylinder block;
- and
- a turbocharger mounted upon a utility pedestal extending between the turbocharger and said hard point with said utility pedestal comprising:
- a mounting pad for the pedestal, with said mounting pad having a plurality of mounting bosses with fastener bores extending therethrough at an acute angle with respect to a horizontal plane, such that fasteners inserted within the fastener bores pass inboard and into threaded bores formed within the hard point;
- an oil supply passage for conveying lubricating oil under pressure from the cylinder block to the turbocharger, with said oil supply passage being operatively connected with one of said ported bosses furnishing lubricating oil under pressure;
- a return oil passage for conveying lubricating oil from the turbocharger to a lubrication system incorporated within the engine;
- and
- a coolant supply passage for conveying coolant under pressure to the turbocharger, with said coolant supply passage being operatively connected with one of said ported bosses furnishing coolant under pressure.
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;
- and
- a turbocharger mounted upon a utility pedestal extending between the turbocharger and a hard point, the hard point configured upon said cylinder block within said valley, with said hard point comprising a plurality of ported bosses for furnishing lubricating oil and coolant to the turbocharger.
