An apparatus and method for multi-mode fuel injection is disclosed. A sleeve is disposed about a fuel injector tip movable between a first and second position and wherein the sleeve is capable of impinging the fuel spray as it enters into the combustion chamber. By impinging the fuel spray, different spray profiles or plumes can be obtained allowing the fuel injector to inject in different modes, including homogenous charge compression ignition.

A dual-function clamping assembly adapted for i) connecting a hydraulically-actuated injector to an engine member, such as a cylinder head, and ii) for sealedly connecting an actuating fluid supply passage between the engine member and an actuating fluid inlet passage of the injector located at one end portion of the injector. The clamp assembly is applicable, for example, for angled-body injectors having the actuator and valve assembly positioned offset from and angled relative to the main longitudinal axis of the injector body.
