ABSTRACT:
A cylinder head assembly for a direct-injection engine is provided. The cylinder head assembly includes a cylinder head at least partially defining a combustion chamber. The cylinder head is sufficiently configured to receive a fuel injector operable to inject fuel directly into the combustion chamber in a spray pattern. An ignition source, such as a spark plug, is spaced from the fuel injector and operable to initiate ignition of the fuel. A fuel mixture diffuser tab is mounted with respect to the cylinder head and extends into the combustion chamber. The fuel mixture diffuser tab is positioned between the fuel injector and the ignition source and is operable to direct a portion of the fuel toward the ignition source. An internal combustion incorporating the disclosed cylinder head assembly is also provided.
