Abstract
A cylinder head arrangement for a direct injected internal combustion engine and particularly one having multiple valves. The cylinder head configuration is such that the injector can be positioned centrally in the combustion chamber and disposed below the overlying ports, which preferably are the inlet ports without significantly detracting from their flow area or without requiring sharp curvature or bends in their configuration that could restrict air flow.
