  • Seal configuration for fuel injector
    Patent number: 11174825
    Abstract: A seal configuration for a fuel injector is disclosed. The seal configuration may include a seal ring within a seal groove of the fuel injector. The seal ring may be formed from a first material. The seal configuration may include a spacer ring within the seal groove of the fuel injector. The spacer ring may be formed from a second material. An outer diameter of the spacer ring may be greater than a diameter of a fuel injector bore of the fuel injector. The spacer ring may be configured to be adjacent the seal ring within the seal groove to form a seal of a fuel injector slot of an engine head of an engine, and the fuel injector slot is configured to support the fuel injector.
