    摘要： An exhaust valve apparatus for an internal combustion engine exhaust valve having a thermally prestressed bender actuator, which moves through a displacement in response to a command signal from a control unit. An actuator drive responsive to motion of the thermally prestressed bender actuator operates an exhaust valve actuator system, which, in turn, operates the exhaust valve. The thermally prestressed electroactive bender actuator and the exhaust valve actuator system operate the exhaust valve to effect engine compression braking.

    摘要： An electrical actuator subassembly, preferably for use in a fuel injector, includes an externally threaded ferromagnetic metallic body, an internally threaded collar, an electrical actuator, an electrical connector, and a plastic cap. In one embodiment, the electrical actuator is a solenoid, while a piezoelectric actuator is used in a second embodiment. The electrical actuator directly controls a pilot valve member positioned between the metallic body and the injector body, and a needle valve which opens or closes a nozzle outlet at the bottom of the injector. The electrical actuator subassembly is attached to a fuel injector body by mating the external threads of the metallic body to the internal threads of the collar. The collar is attached to the injector body with a groove and snap ring configuration.

    摘要： The present invention provides a method and system to control emissions in an engine by controlling spray plume characteristics, such as length and angle. Specifically, a system implementing the present invention includes an fuel injector, an engine cylinder and an electronic control module (ECM). The ECM determines spray plume parameters, including time from start of injection, nozzle hole diameter, pressure differential between the cylinder and fuel in the fuel injector nozzle, and gas temperature and density in the cylinder. Upon determining the spray plume parameters, the ECM calculates the spray plume characteristics and compares them to the optimal spray plume characteristics. The ECM then proceeds to adjust fuel injection characteristics, such as injection on time, rail pressure, and injection timing relative to piston position, to optimize the spray plume.
