Abstract
A fuel injector is mounting in a cylinder head assembly. The cylinder head assembly includes a mounting bore that extends into a recess wall that forms a portion of a combustion chamber. A sleeve is placed within the mounting bore. The fuel injector is secured with a nozzle portion extending through the sleeve. The fuel injector and sleeve interface is sealed by a heat resistant sealing member. The sleeve has any of a number of configurations designed to reduce the temperature of the nozzle. In addition, the nozzle can be recessed within the sleeve to reduce the direct exposure of the nozzle to flames propagated within the combustion chamber.
