摘要： The disclosure illustrates an electronically controlled fuel pump in which a bypass valve regulates its output pressure to a predetermined level above a control pressure. A downstream throttling valve re-regulates the pressure to a predetermined level below a control pressure. The control pressure is established by an electro-hydraulic valve which is, in turn, fed with signals with a microprocessor to provide appropriate control. The use of the control pressure in effect causes a servo action and utilizes the pressure of the fuel to manipulate the valve and minimize the power requirement of the electro-hydraulic valve.

摘要： A system is provided for estimating engine exhaust temperature in accordance with an exhaust temperature model based on a number of engine operating parameters. In one embodiment, the engine exhaust temperature model is based on current values of engine speed, intake manifold temperature, mass charge flow, default fuel command parameters, and a first set of model constants. In an alternative embodiment, the engine exhaust temperature model is based on current values of engine speed, intake manifold temperature, intake manifold pressure, mass charge flow, default fueling parameters, and a second set of model constants including a lower heating value of fuel constant.

摘要： A system is disclosed for estimating the mass flow of recirculated exhaust gas (EGR) from an exhaust manifold to an intake manifold of an internal combustion engine via an EGR conduit disposed therebetween and a fraction of EGR attributable to a mass of charge flow entering the intake manifold. An engine controller is responsive to current values of various combinations of the engine exhaust temperature (ETE), intake manifold pressure (IMP), differential pressure (ΔP) across an EGR valve, and EGR valve position (EGRP) to determine an estimate of EGR mass flow. The controller is further operable to estimate EGR fraction as a function of the estimated EGR mass flow value, mass flow of charge entering the intake manifold, and engine speed.

摘要： An add-on feedback control unit is connected to an existing mechanical governor for a turbocharged engine to control fuel flow to the engine in response to engine load and thereby maintain an adjustable low speed droop for the engine. The preload on the governor control spring is determined by a movable stop, the position of which is controlled by a pivotally mounted reset lever. A control arm is connected to the reset lever at a selected position relative to the pivotal axis of the latter. The control unit includes a housing having an interior chamber separated into first and second subchambers by a diaphragm disposed therein. One side of the diaphragm is subjected to the turbocharger boost air pressure of the engine. The control arm includes a shaft connected to the opposite side of the diaphragm and having an outwardly projecting end portion connected to the reset lever at the selected position to provide feedback in response to engine load. The engine speed is trimmed by adjusting the length of the control arm shaft, and engine speed droop is adjusted by varying the distance between the selected position and the pivotal axis of the reset lever.

摘要： A system for diagnosing fault conditions associated with an air handling system for an internal combustion engine includes an air handling control mechanism responsive to a mechanism command to control fluid flow through an air handling system of an internal combustion engine. An engine controller is configured to compute predicted responses of a number of engine operating parameters each as a different function of the mechanism command, and to compute a corresponding number of correlation coefficients each as a function of one of the engine operating parameter signals and a corresponding one of the predicted responses. The controller is operable to diagnose a fault associated with the air handling control mechanism if at least some of the correlation coefficients are below a first threshold, and to diagnose a properly functioning air handling control mechanism if at least some of the correlation coefficients are above a second threshold.

摘要： A configurable vehicle monitoring device is disclosed that provides two discrete levels of access to configuration routines. In the first level, the owner/operator can configure the unit at a full access configuration level. At the second configuration level, the driver accesses a limited configuration capability to configure certain non-critical operating features. The configurable vehicle monitoring device gathers data from an engine controller over a standard public domain defined data link. The data is analyzed and vehicle operation data is produced including miles per gallon, fuel consumed, trip time, idle time, fuel consumed during idle versus fuel consumed during driving and other pertinent information relevant to fleet or vehicle operation. An electronic audit trail and data regarding power losses provide an indication of device tampering.
