Abstract: The control system controls lean-rich modulation of fueling using a set of engine specific fueling parameter maps. One set of maps is a set of lean fueling maps, and another set is a set of rich fueling maps. The two map sets each comprise a fuel injection pressure map, an EGR valve opening map, and a VGT valve opening map, established for the particular diesel engine, with neither form of modulation requiring post injection. The strategy is represented by a flow diagram and is useful in regenerating an NOx adsorber catalyst in the engine exhaust system in a manner that controls torque so that the regeneration process is transparent to the operator of the vehicle, while producing significant fuel savings.

Abstract: An actuator for actuating a linearly translatable member, such as an engine valve includes a unit trigger actuator, the unit trigger actuator having a trigger being electrically actuatable, a hydraulic cartridge having a selectively translatable component and being operably coupled to the trigger for receiving actuation commands therefrom, the unit trigger actuator being an open loop system. A pivot element is operably coupled to the translatable component and to the engine valve, the pivot element amplifying motion imparted to the pivot element by translatory motion of the piston at the engine valve. A lash adjuster is operably coupled to the pivot element for decoupling the hydraulic cartridge from lash inherent in a plurality of components and assembly of an engine valve arrangement. A method of actuation is further included.

Abstract: The use of green sand is eliminated by replacing green sand molds with all core sand assemblies that provide, during casting, both the internal and external surfaces of a casting, such as a cylinder head or engine block. In the process, a mold is formed from the same core sand that is used to form the core elements defining the internal passageways of the casting. A mold-core carrier is constructed with tapered sides that hold the assembled mold and core elements together during pouring of the molten iron alloy into the mold-core assembly and the cooling period to form the casting. Although the carrier sides can use a refractory liner, preferably the sides are made of replaceable sheet metal backed by an open structural framework to enhance cooling of the casting. After the casting is formed, the core sand from both the mold elements and the core elements is recovered, and may recycled and processed to form further mold elements or core elements or both.

Abstract: A delay device for use with a fuel injector, the fuel injector having an electric controller for controlling the flow of a high pressure actuating fluid responsive to initiation and cessation of a pulse width command, the pulse width command defining the duration of an injection event, and an intensifier being in fluid communication with the controller, the intensifier being translatable to increase the pressure of a volume of fuel for injection into the combustion chamber of an engine; the delay device includes an apparatus, shiftable between a first disposition and a second disposition over a certain period of time after initiation of the pulse width command, the period of time effecting a delay in initiation of fuel injection after initiation of the pulse width command. A fuel injector including a delay device. A method of controlling a fuel injection event, includes the steps of flowing an actuating fluid from the controller to an intensifier responsive to a pulse width command, pressurizing a volume of fuel by means of the intensifier, flowing a high pressure fuel from the intensifier to an injector nozzle, and interposing a delay in at least a portion of the flow of fuel to the injector nozzle.

Abstract: A control system and method for an EGR valve, particularly in a diesel engine. A processor processes data in feedback control of the position of the valve element to develop from the data a position control signal for setting the extent to which the valve is open. The processing includes processing data corresponding to actual position of the valve and data representing a desired position of the valve to develop a position error signal, processing data that defines actual EGR rate and data representing a desired EGR rate to develop a rate error signal, and processing the position error signal and the rate error signal to develop the position control signal. Emission control system event monitors flag potential error sources in their incipiency to afford opportunity for correction before mandatory logging occurs.

Abstract: A fluid delivery system for delivering a supply of a fluid from a fluid source to at least one fuel injector includes a rail for conveying a fluid and being positionable proximate the fuel injector. The rail has a fluid passageway defined therein, the fluid passageway being in fluid communication with the source of fluid. A connector is in fluid communication with both the rail and with the fuel injector for fluidly connecting the rail to the fuel injector. The connector is universally shiftable in three orthogonal axes for accommodating static tolerances existing between the rail and the fuel injector and for accommodating dynamic relative motion between the rail and the fuel injector.

Abstract: A device and method for catalytic reduction of NOx in gaseous products of a combustion process before entry into the atmosphere. The gaseous and particulate products of a combustion process flow radially through a radial flow particulate filter element (24) that is effective to trap particulate matter, and are then directed axially through a collector (26). An injector (30) introduces a reductant into an axial end of the collector for entrainment with axial flow through the collector in a direction away from the injector. Flow leaving the collector is directed through an SCR catalyst (40) where catalytic reduction of NOx occurs.

Abstract: A method of determining a need to perform regeneration of a diesel particulate filter in a diesel engine exhaust predicts a soot load of a diesel particulate filter with a pressure change based soot load estimate based upon a pressure change across the diesel particulate filter at a first time and a second time. A restriction sensitivity for the diesel particulate filter is calculated based upon the pressure change across the diesel particulate filter at the first time and the second time. The method transitions from the pressure change based soot load estimate to a model based soot accumulation estimate of the soot load of the diesel particulate filter upon the restriction sensitivity falling below a predetermined threshold. Regeneration of the diesel particulate filter is requested after the estimated soot level reaches a preset level based upon the soot accumulation model.
