Filed:

Sep 16, 1999

Appl. No.:

9/397170

Inventors:

Karen A. Alpan - LaGrange IL
David G. Bergman - Sugar Grove IL
David L. Rowland - Burr Ridge IL

Assignee:

International Truck and Engine Corporation - Chicago IL

International Classification:

F01M 1106

US Classification:

123196R

Abstract:

The present invention describes an engine having an oil pan (100) with a pick-up tube (140) for moving oil from an oil reservoir (105) to an oil pump (130). An engine crankcase (110) is connected to a front cover (120) having a front half (122) and a back half (124). The oil pan (100) is connected to the crankcase (110) and the front cover (120). A pick-up tube (140) is disposed along the oil pan (100) and connects the oil reservoir (105) to an inlet path (128) formed by the front half (122). A nipple (150) connects to the pick-up tube (140) to the front half by being inserted into an opening (129) of the inlet path (128). A gasket (160) is disposed adjacent to the nipple (150) and between the pick-up tube (140) and the front half (122). An alternate embodiment omits the nipple (150).

Abstract:

An internal combustion engine includes a spaced apart surge tank, the surge tank being an integral component of a pressurized liquid engine cooling system. A first conduit fluidly couples the surge tank to a component of the pressurized liquid engine cooling system. The conduit has an internal fluid passageway defined therein. The conduit is heat responsive, an application of heat to the conduit acting to effect a contraction of the fluid passageway. Further, a method of controlling fluid flow in a conduit connecting the surge tank to a component of a pressurized liquid engine cooling system, comprises the steps of: forming the conduit of a heat responsive material; flowing a fluid through the conduit; running the engine to an elevated fluid temperature; and contracting the conduit fluid passageway responsive to the heating of the conduit caused by the fluid flow therein.
