ABSTRACT:
A combustion gas seal assembly adapted for a fuel injector installed in a cylinder head of an engine. The seal assembly includes a hollow adapter adapted to be connected to the cylinder head, an injector case positioned in the adapter, and a flexible annular seal positioned between the case and the adapter. The case and adapter each define opposed annular seat portions contacting one another. At least one of the seat portions of the case and the adapter defines an annular groove in which the flexible annular seal is positioned. The combustion gas seal assembly prevents pressurized combustion gas, originating from an engine combustion chamber, from leaking past the interface between the case and the cylinder head. The assembly also facilitates low cost retrofitting or adaptation of new or different fuel injectors to an existing cylinder head of a conventional engine.
