US 2011/0214630 A1 · ENGINE BLOCK ASSEMBLY FOR INTERNAL COMBUSTION ENGINE

Abstract

An engine block assembly for an internal combustion engine comprises a cylinder portion having a plurality of cylinder walls disposed therein. A water jacket, having opposed side walls, extends about the plurality of cylinder walls to define a coolant flow path. A coolant inlet in fluid communication with the water jacket delivers coolant thereto and a coolant outlet in fluid communication with the water jacket removes coolant therefrom. Opposed sealing shoulders extend into the coolant flow path from the water jacket side walls and a longitudinally extending coolant baffle is disposed in the water jacket adjacent to the sealing shoulders. The coolant baffle includes a baffle sealing face configured to engage the opposed sealing shoulders to direct the coolant entering the water jacket in a single direction around the cylinder walls of the cylinder portion.

An engine block assembly for an internal combustion engine comprising:

a closed deck cylinder portion having a plurality of cylinder walls disposed therein;
a water jacket, having opposed side walls, extending about the plurality of cylinder walls to define a coolant flow path around the cylinder walls;
a coolant inlet in fluid communication with the water jacket for delivery of coolant thereto;
a coolant outlet in fluid communication with the water jacket for removal of coolant from the water jacket;
first and second, opposed sealing shoulders extending into the coolant flow path of the water jacket from the water jacket side walls, the cooling shoulders extending the height of the water jacket;
an opening extending through the closed head cylinder portion adjacent to the opposed sealing shoulders;
and
a longitudinally extending coolant baffle inserted into the water jacket through the opening in the closed cylinder head portion, the coolant baffle having a baffle sealing face having first and second sealing surfaces configured to engage the opposed sealing shoulders to define a face seal therebetween and to close a portion of the water jacket against coolant flow and direct the flow of coolant entering the water jacket through the coolant.
