摘要： An exhaust gas recirculation system for an internal combustion engine by which a portion of exhaust gases produced by the engine is recirculated from an exhaust line of the engine into an intake line of the engine introduces the EGR exhaust gas flow into the intake passageway via a mixer ejector which is provided with mixer lobes and a diffuser downstream of the lobes. The mixer ejector enhances the momentum transfer from the intake flow to the exhaust flow, and in this way, the static pressure of the exhaust flow at the entrance to the mixing region is decreased, thereby increasing the differential pressure across the EGR tube and increasing the exhaust flow. In a second embodiment, in addition to, or instead of, using the special ejector construction of the first embodiment, an ejector pump is located in the EGR tube. The ejector in the EGR tube is connected to the vehicle air system compressor or turbocompressor and serves to pump the exhaust gases to the engine intake passageway. This embodiment enables a more precise controlling of the EGR rate to be obtained, and can provide more EGR flow that which could be obtained with an intake ejector or venturi alone.

摘要： A pneumatic throttle system for maintaining sufficient exhaust pressure to maintain exhaust flow through an EGR system. The throttle system includes an apertured throttle plate positioned to selectively restrict the flow of exhaust gasses exiting the engine. Movement of the plate is controlled by a pneumatic piston assembly connected thereto. The piston assembly includes a piston movably mounted within a gas-tight chamber. The piston head functionally divides the chamber into two variable-volume portions. The first chamber portion is pneumatically connected to the intake manifold, while the second portion is pneumatically connected to the exhaust manifold. The gas pressure in one chamber portion relative the other determines the relative volume of each chamber portion according to P1V1=P2V2. The piston moves within the chamber to satisfy the above relationship. As the piston moves in response to changes in the respective manifold pressures, the throttle plate moves to increase or decrease gas flow therethrough, accordingly changing the exhaust back-pressure.

摘要： A method and system for preparing a suite of test scripts for testing a proposed network management application. The proposed network management application, termed a subsystem control facility (SCF), is first defined as a set of requirements with the aid of a developmental tool incorporating a subsystem knowledgebase and a test generation knowledgebase. The subsystem knowledgebase contains the rules governing the operation of a given network and a library of permitted commands, objects, attributes, modifiers and other data. The test generation knowledgebase includes information relating to those commands and object specific to the proposed subsystem control facility set of requirements. A user interface coupled to the knowledgebases permits the selection of types of tests and specific commands and objects to be tested. Once test selection has been specified, test scripts corresponding to the selected tests are generated from the first and second knowledgebases for use in testing the proposed set of requirements for the SCF prior to coding the SCF. The suite of test scripts can be used to test the proposed SCF set of requirements, detect nonconformance with the rules and permit modification of the proposed set of SCF requirements. If necessary, additional testing may be performed using the same test scripts or a subset thereof, until the test results indicate no errors and a minimum number of warnings. Thereafter, the SCF product module can be coded. Errors in the developmental stage can be thus corrected early in the developmental cycle.

摘要： A fuel measurement and control system for a gaseous fuel engine having a solenoid actuated fuel flow control valve which is electronically actuated to control a desired metering duration when the control system is operating in a fuel flow control mode. The fuel measurement and control system further includes mode control valve for switching the control system between a fuel flow control mode and a positive fuel shutoff mode, wherein the fuel flow control valve is prevented from opening when the control system is operating in a positive fuel shutoff mode. The fuel flow control valve includes a pressure balance chamber to balance the biasing forces acting on the valve from the gaseous fuel, wherein gaseous fuel is introduced into the pressure balancing chamber to provide the balancing forces. The mode control valve connects the pressure balance chamber to either the fuel supply or the air stream mixer inlet to provide the desired pressure in the pressure balance chamber, wherein the fuel flow control valve is biased to a closed position and prevented from opening when the pressure balance chamber is connected to the air stream mixer inlet and the fuel flow control valve is pressure balanced and may be actuated to control fuel flow when the pressure balance chamber is connected to the gaseous fuel supply. A damping chamber is connected to the pressure balance chamber for damping the oscillations of the solenoid actuator and further reducing the effects of engine vibrations on the solenoid actuator.

摘要： A gas flow network in combination with a highly turbocharged diesel engine for the blending of either EGR gas or blow-by gas from the crankcase vent with fresh charge air is disclosed. In the diesel engine assembly which incorporates the flow network for EGR gas, a venturi conduit and control valve combination is positioned between tile intake manifold and aftercooler and is connected to a flow line carrying the EGR gas. When the turbocharged diesel engine assembly is configured with a flow path for blow-by gas, the venturi and control valve combination is positioned between the intake manifold and aftercooler and is connected to a flow line carrying blow-by gas. These systems utilize a low static pressure at the narrow throat of the venturi so as to induce the flow of EGR gas or blow-by gas into the fresh charge air, the flow being controlled by the state of the control valve.

摘要： A crankcase ventilation system for a vehicle includes an arrangement of flow conduits and control valves which cooperate with a two-chamber accumulator and with various vehicle components to route crankcase gases to the intake manifold. The primary vehicle components include a compressor, an aftercooler positioned downstream from the compressor, and an engine having an intake manifold and a crankcase. One chamber of the accumulator is coupled by one conduit to the inlet side of the compressor and by a second conduit to the outlet side of the compressor. These two conduits are controlled by a dual valve arrangement. The other chamber of the accumulator is connected by one conduit to the crankcase and by a separate conduit to the intake manifold. Each conduit includes a control valve. The system operates on pressure differences existing between these various components. The cycle begins by opening the conduit which is connected to the inlet side of the compressor. This creates a low pressure on that side of the diaphragm. Due to their higher pressure, the crankcase gases empty into the accumulator and when a predetermined pressure is reached, the various valves change state, allowing the high pressure side of the compressor to empty into the accumulator. This pushes the lower pressure crankcase gases out of the accumulator through a different conduit to the intake manifold. These crankcase gases are then burned in the cylinders and the crankcase gases are not vented directly to the atmosphere.
