摘要： An arrangement for authorizing transfer of software into one or more embedded systems includes a service/recalibration tool connectable to one or more embedded control units. A service technician or other operator of the tool obtains a hardware identification code corresponding to an identifier associated with an embedded control unit, or to an identifier associated with the tool, and also establishes a download number corresponding to the desired number of downloads when the identifier is associated with the tool, and a software identification code corresponding to an identifier of software to be transferred from the tool to the embedded control unit, and provides this information to a provider of the software who creates one or more passwords based thereon. The service technician may then use the one or more passwords to transfer one or more password-protected portions of the software from the tool into the one or more embedded control units.

摘要： A method and apparatus is disclosed for recursively estimating vehicle mass and/or aerodynamic coefficient of a moving vehicle. The vehicle speed and push force data are collected and a segment of qualified data is then selected from the collected data. Newton's second law is integrated to express vehicle mass and/or aerodynamic coefficient in terms of vehicle push force and vehicle speed. This expression is then used in a recursive analysis of the qualified data segment to determine an estimated vehicle mass and/or aerodynamic coefficient.

摘要： A fuel injector for use in a diesel engine which is equipped with an engine brake governed by a hydraulic circuit includes an injector body with a hollow interior, a plunger located within the injector body, a moveable coupling positioned within the injector body, a nozzle for the dispensing of fuel, and a variable rate return spring which is positioned between the injector body and the moveable coupling. The variable return spring is designed with a variable pitch between adjacent coils such that the pitch between coils near the end(s) of the spring is reduced over that near the center of the spring. The use of the variable rate spring is intended to address the problem of premature fatigue failures caused by the return spring oscillating at or above its natural frequency. The oscillations are induced due to the exhaust valve opening and closing events and are transmitted directly through the engine brake hydraulic circuit to the injectors by way of the injector push tube. With the variable rate spring, if resonance occurs at one harmonic, the end coils close and open up, thus changing the natural frequency of the spring and tending to throw it out of resonance. In this manner, the spring will not oscillate at its natural frequency since the natural frequency is changing.

摘要： A closed crankcase ventilation system for a turbocharger internal combustion engine which uses differential pressure between the turbo compressor inlet and the crankcase to force blow-by gases through a separation device. The zone of low pressure of the turbo compressor inlet is located at the innermost diameter of the compressor inlet shroud. The difference between the pressure in the compressor inlet and the crankcase creates a vacuum which pulls gas from the crankcase into the ventilation system. The ventilation system includes a high restriction separator for removing oil from the blow-by gases. A control valve bypasses the separation device when insufficient pressure differential exists to drive the separator. Additionally, a system for ventilating crankcase gases from a crankcase of the engine includes a first flow passage communicating between the crankcase and a turbocharger of the engine, an high restriction separator positioned in the flow passage for separating air contaminant mixtures from crankcase gases, a first connection for connecting a first end of the flow passage to the crankcase, a second connection for connecting a second end of the flow passage to a predetermined point of the turbocharger, a second flow passage communicating between the first flow passage and an intake manifold of the engine, and a bypass flow passage for bypassing the separator. In this case, the crankcase gases are directed through the separator during heavy load, light load and idle operating conditions when sufficient vacuum exists to draw the crankcase gases through the coalescing filter and through the bypass flow passage when a sufficient vacuum is not present.

摘要： An improved turbocharged internal combustion engine is provided having a system and method for preventing a rapid decrease of turbocharger power during rapid fuel reduction transients in engine operation due to reductions in fuel flow rate to the engine. The engine includes a turbocharger power enhancing system including an exhaust valve control device capable of varying the timing of opening of the engine exhaust valves. The turbocharger power enhancing system also includes a processor which generates a control signal when a reduction in the fuel delivery rate is detected. The control signal operates the exhaust valve control device to advance the timing of opening of the exhaust valves to cause additional exhaust gas to be delivered to the turbine thereby preventing a rapid decrease of compressor speed and preventing compressor surge. The system and method may require the presence of one or more other engine operating conditions before the exhaust valve timing may be advanced, such as a minimum intake pressure, a minimum reduction in the fuel rate, a fuel rate reduction within a specific time period and/or an engine speed below a predetermined value.

摘要： A control valve comprising a valve housing including a valve cavity, an inlet means formed in the valve housing for directing fluid into the valve cavity, and an outlet means formed in the valve housing for directing fluid out of the valve cavity. The control valve further includes a valve element mounted for reciprocal movement in the valve cavity between open and closed positions and biased toward the closed position by fluid pressure forces. A valve seat is associated with the valve element which engages the valve seat when in the closed position and permits flow between the valve seat and the valve element when in the open position. A flow force inducing means is positioned adjacent the valve element for redirecting fluid from the inlet means through a predetermined flow path arranged relative to the valve element to cause fluid flow to impact the valve element and create flow induced forces of sufficient magnitude necessary to advantageously counteract the fluid pressure forces.

摘要： A method for controlling a vehicle engine coolant fan. Because operation of the engine coolant fan creates a power drain upon the engine, it is undesirable to operate the coolant fan when the engine is fueled. Conversely, a power drain upon the engine is desirable when an attempt is being made to slow the vehicle. Consequently, the present invention requests activation of the coolant fan whenever a power drain upon the engine is desirable. Not only is this desirable in order to slow the vehicle, but it also lowers the coolant temperature, thereby reducing the chance that the coolant fan will have to be operated in the future when such operation is undesirable.

摘要： The present invention relates to a method and apparatus for control of current rise time during multiple fuel injection events. The invention utilizes a single boost voltage supply circuit, in which the boost capacitor is designed to store slightly more than twice the total energy required to pull-in a single fuel injector solenoid during the prescribed time. A reference waveform simulating the desired current rise time is compared to the actual boost voltage produced by the circuit. The boost voltage is modulated (switched on and off) in order to maintain the boost voltage within a predetermined window around the reference waveform. This modulation will compensate for any droop in boost voltage at the time of actuation, and will also compensate for two solenoids being actuated at the exact same time. It is only necessary that a nninimum amount of energy be stored in the boost capacitor at the completion of an actuation event, and the level of this minimum amount of energy can easily be determined by analysis or experimentation. Additionally, it is very easy to modify the shape and duration of the reference waveform, thus allowing for a very flexible solenoid drive circuit whose pull-in time and boost energy consumption can be easily changed to meet the requirements of an application without modifying the LRC time constants of the system.

摘要： A swirl tip injector nozzle housing is provided for a fuel injector which includes a fuel atomization enhancing feature for creating effective fuel atomization and breakup during discharge from the injector. The fuel atomization enhancing feature includes a plurality of curvilinear spray holes having an angle of curvature equal to approximately 90 degrees. Fuel flowing from the inlet of each spray hole to the outlet is induced, by the 90 degree angle of curvature, to flow through a tangential flow path or swirl within the spray hole causing rapid spreading and breakup of the fuel jet spray upon exiting the outlet of the spray hole. The fuel atomization enhancing feature may also include positioning each spray hole so as to extend orthogonally from the interior surface of the fuel cavity to create optimal entry of the fuel into the tangential flow path.
