IGNITION-ASSISTED FUEL COMBUSTION SYSTEM

Ignition-Assisted Fuel Combustion System Conventional direct injection internal combustion engines will not completely ignite and burn relatively lower-cetane-number fuels such as 100 percent methanol or ethanol because the fuel spray injection pattern usually cannot carry or propagate a flame to all the injected fuel which is typically made up of individual fuel streams which are separated by pockets of fuel-deficient intake air. The present fuel combustion system includes a fuel ignition-initiating device such as a glow plug and apparatus for interconnectedly contacting and continuously bridging all of the individual fuel streams with an auxiliary cloud of well-atomized fuel. In this manner, a flame initiated by the fuel ignitioninitiating device is rapidly and completely propagated via the auxiliary cloud of fuel to all the individual fuel streams.

CONTROL CIRCUIT FOR POSITIONING AN EARTHMOVING BLADE

Control Circuit for Positioning An Earthmoving Blade Fluid control circuits are commonly used to control actuation of a pair of cylinders for positioning an earthmoving blade.

The subject fluid control circuit includes a selector valve for determining the direction of fluid flow to and from the head end and rod ends of the tilt cylinders and a single control valve for modulatably controlling the fluid flow from the pump to the cylinders. With this circuit, the selector valve can be prepositioned in the desired position prior to actuating the control valve so that positioning of the blade is readily controlled by manipulation of only the single control valve.

REMOTE SENSOR WITH COMPENSATION FOR LEAD RESISTANCE

Remote Sensor With Compensation For Lead Resistance An apparatus increases the accuracy of a signal delivered from a remote analog sensor to an analog to digital converter.

It is, therefore, advantageous to closely control the voltage applied to the sensor. The apparatus monitors the voltage drop across the lead lines which extend between the sensor and a power supply and increases the voltage applied to the sensor by a magnitude corresponding to the lead line voltage drop. The accuracy of the sensor is preserved independent of the lead line length and resistance.

Efficient Wave Form To Control Fuel System

An efficient control wave form is utilized to actuate the solenoids of a fuel system to reduce boost power/energy consumption. The solenoid is initially energized by applying a boost voltage from an electronic controller across a solenoid coil circuit. The electronic controller monitors the current level in the solenoid coil circuit, and changes to a reduced battery voltage when the current level in the solenoid coil circuit reaches a predetermined trigger current. The controller then maintains a pull-in current based upon battery voltage for a pull-in duration that initiates movement of the solenoid armature from an initial air gap position toward a final air gap position. After the pull-in duration, the current level is dropped to a hold in level for the remaining duration of the actuation event.
