  • Patent number: 10516412
    Abstract: An interleaved digital-to-analog converter (DAC) system may include a first sub-DAC and a second sub-DAC and may be configured to provide both a converter output signal and a calibration output signal. The converter output signal may be provided by adding the first sub-DAC output signal and the second sub-DAC output signal. The calibration output signal may be provided by subtracting one of the first and second sub-DAC output signals from the other. The calibration output signal may be used as feedback to adjust the phase of one of the sub-DACs relative to the other, to promote phase matching their output signals.

  • Patent number: 7013212
    Abstract: A compression ignition engine (10) has a control system (24) for processing data, one or more cylinders (16), a fueling system (18), and a variable valve actuation mechanism (20). Control system (24) develops both fueling data for fueling the engine and timing data representing time during the engine cycle for intake valve closure to a cylinder that will endow the cylinder with an effective compression ratio (ECR) appropriate to current engine operation for causing auto-ignition to occur near or at top dead center in the engine cycle. During a compression upstroke, the cylinder is fueled according to the fueling data and intake valve closure for the cylinder is performed according to the timing data. This creates an air-fuel mixture that is increasingly compressed to the point of auto-ignition near or at top dead center.

  • Patent number: 6742504
    Abstract: A mechanical oscillator for attenuating pressure waves formed in a rail having a volume of fluid therein includes a rigid enclosed fluid cavity having a selected volume, the volume communicating with the rail actuating fluid though an orifice having a select volume for containing actuating fluid, the orifice having an aperture in fluid communication with the actuating fluid selected such that when an pressure wave impinges on the aperture of the orifice, the motion of the actuating fluid in the volume of the orifice is set to vibrating, the vibrating acting to excite the actuating fluid within the enclosed volume, a resulting amplified motion of the actuating fluid in the orifice, due to phase cancellation between the actuating fluid in the volume of the orifice and the actuating fluid volume in the enclosed cavity, causing energy absorption of the pressure wave due to frictional drag in and around the orifice. An pressure wave attenuator and a method of attenuation are also included.

  • Patent number: 6604507
    Abstract: A fuel injector includes a spool control valve, a plunger which moves in a fuel pressure chamber between retracted and full stroke positions. The fuel injector may include a spill port for spilling fuel from the fuel pressure chamber, the spill port being open at the start and closed by the translating motion of the plunger to delay the start of injection. The fuel injector chamber may further include a control port which is closed at the start of plunger motion and is opened by the plunger to connect the pressure chamber to a needle back chamber to bias the needle valve closed. The needle back chamber becomes isolated from the pressure chamber by further movement of the plunger and includes a pressure control passage to allow the pressure therein to decay upon control port closure, thereby effecting split injection or rate shaping.
