摘要： An apparatus and method for causing a fuel injector to overcome its inherent fuel injection pressure threshold long enough to completely inject a predetermined volume of fuel during each fuel shot associated with a particular fuel injection event. The fuel injector is in electrical communication with an electronic controller for receiving control signals of pre-calculated timing and duration therefrom. Furthermore, the fuel injector is in mechanical communication with a cam follower. A camshaft has a cam profile in mechanical communication with the cam follower, the cam profile including at least one lobe operable to generate pressure within the fuel injector sufficient to overcome the fuel injection pressure threshold in predetermined intervals in conjunction with the control signal of the electronic controller.

摘要： A fuel injection control system and method for controlling multiple fuel injections to a cylinder of an engine during a fuel injection event based upon engine operating conditions, the control system including an electronic controller coupled to an electronically controlled fuel injector, the controller being operable to determine and deliver a fuel injection current signal to the fuel injector to adjust the duration of each fuel shot associated with a particular fuel injection event to compensate for the inherent delay of the fuel injector in responding to the injection current signal, that is, the delay between the start of the injection current signal and the actual start of the fuel injection.

摘要： In a power transmission or generation apparatus having a source of heated pressurized air, the problem of achieving rapid controlled engagement of a hydraulically actuated clutch at low ambient temperatures is solved by utilizing a portion of that heated pressurized air for heating only that small control volume of hydraulic fluid within a clutch control circuit needed to achieve rapid actuation and stable control of the hydraulic clutch. Our invention is thus particularly applicable in a power transmission or generation apparatus having a gas turbine engine, or a turbocharged piston engine as the prime mover. With gas turbine engine powered units, our invention contemplates the use of compressor discharge air, rather than exhaust products for heating the hydraulic fluid. Similarly, for piston engines our invention contemplates the use of turbocharger discharge air rather than exhaust products. In one embodiment a clutch and a control circuit are provided in which the fluid volume of the control circuit is minimized, and fluid removal features are provided to effectively drain all residual fluid from a portion of the control circuit following disengagement of the clutch. On subsequent start-up from cold ambient temperatures, the drained portion of the control circuit is filled with pre-heated fluid prior to engagement of the clutch thus eliminating problems of slow response and controllability encountered due to cold viscous fluid in prior clutch control circuits.
