Abstract

An injector clamp (80) for securely clamping a plurality of fuel injectors (14) to an engine housing (16) is described. The clamp comprises a plurality of rigid clamp regions (82) separated by flexible clamp regions (84), each of the clamp regions (82) providing clamping means (56) for clamping an injector (14) to the engine housing (16). The injector clamp (80) further comprises a fuel passageway (22) for fluidically connecting a high pressure fuel inlet to the plurality of fuel injectors. The flexible clamp regions (84) allow the injector clamp (80) to bend to adapt to variations of height of each fuel injector (14). An injector assembly suitable for mounting in an engine housing is also described.
