Abstract
Disclosed herein is an internal combustion engine including an ignition port having an outlet opening into a cylinder combustion chamber, a spark plug mounted in the ignition port, and a deflector located on the cylinder head adjacent the ignition port outlet. The deflector surrounds the side of ignition port outlet closest to the fuel intake port and diverts lubricant and/or other heavy residuals collecting on the cylinder head around the ignition port outlet so as to minimize fouling of the spark plug.
