Abstract

A modular system for constructing a coolant core/cylinder head structure, is described. The system comprises a modular coolant core having an inlet and an outlet, a plurality of passageways within an interior space of the coolant core, the passageways fluidly connecting, which create a specific coolant flow pattern between the inlet and the outlet, wherein the coolant core has a single pattern geometry for assembling into the cylinder head core box. Use of the individual modular coolant cores permits construction of customized cylinder heads, which use the same tooling across multiple engine platforms, while providing more uniform coolant velocity and heat rejection from cylinder to cylinder and improved structure with more uniform clamping load between head bolts around the combustion chamber.
