Abstract
Abstract An engine intercooler has an inlet passage receiving heated air from the turbocharger, an intercooler core and a plurality of outlet passages directing air to the engine cylinders. The housing of the intercooler is divided by the core into a plenum chamber for receiving air and an air intake chamber delivering air to the engine cylinders by way of the outlet passages. The core is supported at its opposite ends and is also supported by a perforated intermediate support plate which includes a pair of deflector surfaces directing incoming air in opposite directions to aid in distributing air evenly through all portions of the intercooler core.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
178 words
An internal combustion engine comprising, an air intake system including, means defining an inlet passage and a plenum chamber for receiving air from a supercharger, an air intake chamber and passages for supplying air to the engine cylinders, means defining an intercooler core chamber for cooling air flowing from said plenum chamber to said air intake chamber including chamber walls intermediate the plenum chamber and said intake chamber, an intercooler core having a plurality of cooling fluid conduits extending the length of said core mounted in said core chamber, support means on the ends of said intercooler core carrying the end of said core, a plurality of cooling fins interleaved between the end supports on said cooling fluid conduits, a perforated intermediate support plate on the center portion of said intercooler core having mating side surfaces adjacent said core chamber walls, an air deflector on said support plate aligned with said inlet passage for distributing air over said intercooler core, damping means on said core chamber walls engaging said support plate providing an intermediate support for damping vibrations.
Claim 2
Dependent Claim
178 words
An internal combustion engine comprising, an air intake system including, means defining an inlet passage and a plenum chamber for receiving air from a supercharger, an air intake chamber and passages for supplying air to the engine cylinders, means defining an intercooler core chamber for cooling air flowing from said plenum chamber to said air intake chamber including chamber walls intermediate the plenum chamber and said intake chamber, an intercooler core having a plurality of cooling fluid conduits extending the length of said core mounted in said core chamber, support means on the ends of said intercooler core carrying the end of said core, a plurality of cooling fins interleaved between the end supports on said cooling fluid conduits, a perforated intermediate support plate on the center portion of said intercooler core having mating side surfaces adjacent said core chamber walls, an air deflector on said support plate aligned with said inlet passage for distributing air over said intercooler core, damping means on said core chamber walls engaging said support plate providing an intermediate support for damping vibrations.
Claim 3
Dependent Claim
53 words
An internal combustion engine as set forth in claim 1 wherein said air divider on said intermediate support plate of said intercooler core includes means defining arcuate deflecting surfaces for deflecting incoming air toward both ends of said intercooler core for even distribution of air flow through all portions of the cooling core.
Claim 4
Dependent Claim
33 words
An internal combustion engine as set forth in claim 1 wherein said damping means for said intermediate support plate includes resilient mounts for supporting said plate on opposing sides of said intercooler core.
Claim 5
Dependent Claim
51 words
An internal combustion engine as set forth in claim 1 wherein said inlet passage defines a central passage for directing air to said air deflector of said support plate and wherein said air deflector includes a pair of surfaces directing air in opposite directions, toward opposite ends of said plenum chamber.
Claim 6
Dependent Claim
43 words
An internal combustion engine as set forth in claim 1 wherein said support plate defines symmetrical arcuate air deflecting surfaces for directing incoming air toward both ends of said intercooler core for uniform air flow through all cooling surfaces of said intercooler core.
Claim 7
Dependent Claim
67 words
An internal combustion engine as set forth in claim 1 wherein said inlet passage includes means centrally mounting said inlet passage on said plenum chamber for supplying air to said plenum chamber, means axially aligning said air deflector with said inlet passage on opposing sides of said support plate for diverting air flow to both ends of said intercooler core for uniform flow through the intercooler core.
Claim 8
Dependent Claim
32 words
An internal combustion engine as set forth in claim 1 wherein said support plate includes a screw fastener for threadedly engaging a threaded openind in the wall of said intercooler core chamber.
Claim 9
Dependent Claim
25 words
An internal combustion engine as set forth in claim 1 wherein said damping means includes two diametrically mounted resilient supports supporting said intermediate support plate.
Claim 10
Dependent Claim
37 words
An internal combustion engine as set forth in claim 1 wherein said core defines a circular cross sectional configuration of said intercooler core, means defining arcuate intercooler core chamber walls mating the external surface of said core.
Claim 11
Dependent Claim
26 words
An internal combustion engine as set forth in claim 1 wherein said intermediate support plate includes two set screws mounted in the intercooler core chamber walls.
