Thermal structure concept for an air-cooled high-performance cylinder head of a boxer engine with asymmetric three-valve architecture

Abstract

Air-cooled cylinder head (1) for a boxer engine with at least one combustion chamber, characterized in that the cylinder head (1) has a thermal structure concept comprising an asymmetric three-valve arrangement with two inlet valves (2) and a single exhaust valve (4), thermal material bridges formed between the combustion chamber and the cooling structure, and a cooling structure, wherein the aforementioned features work together functionally to improve heat conduction in the area of ​​the exhaust valve seat and to reduce thermally induced material stresses.
