Reciprocating piston internal combustion engine with a cylinder head equipped with inlet and exhaust valves

摘要

In order to prevent losses in volumetric efficiency due to the limiting of a combustion chamber depression (21) in the cylinder head (10), especially in an in-line V-internal combustion engine, mutually overlapping combustion chamber extensions (22, 23) are provided next to at least one of the valves (12). <IMAGE>
