An EGR flow path for recirculating exhaust gas from the exhaust system to the intake system includes an EGR valve (48) for controlling EGR flow. The EGR flow path is connected to the exhaust system upstream of the throttle valve and downstream of both the CDPF and the turbine, and to the intake system upstream of the turbocharger compressor Valves (36, 48) are under coordinated control provided by an engine control system (24) for selectively restricting the respective valves to attain desired EGR flow.

Abstract: A method of determining an adjusted boost signal includes determining a steady-state boost for a turbocharger (103, 105) for an internal combustion engine (101). The steady-state boost is adjusted (509, 513) for at least one of current transient speed conditions and current transient load conditions of the internal combustion engine, yielding an adjusted boost signal. The adjusted boost signal is sent (517) to the turbocharger.

During a timing adjustment period, the timing for fuel injection(s) may be adjusted (405) incrementally, e.g., in a series of steps or increments, and/or based at least in part on the time elapsed since the detected of the change in the number of fuel injections.

Abstract: A method and apparatus for providing broadcast group data when a subscriber unit provides a data service message to a data gateway. The data service message includes identity of the subscriber unit and identity of at least one targeted host. The data gateway determines the data service message is for group data broadcast and temporarily stores the identity of the subscriber unit and the identity of the at least one targeted host. Then, the data gateway receives data from a targeted host of the at least one targeted host. When the identity of the targeted host is verified, the data gateway provides the data to a group of subscriber units, wherein the subscriber unit is included in the group of subscriber units.

Abstract: A valve operator position is determined for an exhaust gas recirculation valve (117) for an internal combustion engine (101). The valve position may be adjusted (313) for transient engine speed conditions and/or adjusted (309) for transient engine load conditions. During high transient states, the EGR valve is closed more, to allow more air to reach the cylinders of the engine, thereby improving engine performance.

The light source is manually or automatically activated. The light source is activatable over any angle between the cover and the rest of the housing, thus an angle for turning on the light source is selectable.

Abstract: An engine (10) has a fueling system that uses hydraulic fluid to force fuel into engine combustion chambers via fuel injectors. Pressure of the hydraulic fluid is determined by a steady state strategy (ICP—DES—1) and a transient strategy (34, 36) that develops transient data values to account for certain transients in engine operation by processing engine speed data and data representing rate of change of engine speed, and data representing engine fueling to develop sub-strategy data values (ICP—FF—TS, ICP—FF—TL) for a transient component. The data values ICP—DES—1, ICP—FF—TS, and ICP—FF—TL are algebraically summed to develop a data value (ICP—DES—2) for a transient-modified desired hydraulic fluid pressure that is compared with a data value for actual hydraulic fluid pressure (ICP) to develop a data value for an error signal ICP—ERR. The data value for the error signal is processed according to a closed-loop strategy to develop a data value that controls the hydraulic fluid pressure.

Abstract: An apparatus for and method of utilizing the temperature of one electronic component (203) reduces pre-cycle warm-up of another component (107 or 113). For example, a temperature sensor (205) for a driver (203) of an electronic component (107 or 133), such as a glow plug or fuel injector coil, is utilized to determine when a temperature condition is exceeded. When that temperature condition is exceeded (305), pre-cycle warm-up for the electronic component associated with the component is reduced (311).

Abstract: A light source is disposed in a cavity in an enclosure that supports a part of the wall. The enclosure may be disposed substantially within the wall, such that the enclosure does not provide an obstacle to those moving near the wall. Because the enclosure is capable of supporting a part of the wall, the enclosure may be substituted for one or more substructures of the wall, including, but not limited to, concrete blocks, cement blocks, bricks, cinder blocks, and combinations thereof. The enclosure may be disposed at most any height in the wall.

Abstract: A connection system for exhaust gas recirculation (EGR) in a diesel engine has an EGR conduit, an exhaust manifold, and a sealing strand. The EGR conduit forms a first surface surrounding an inlet. The exhaust manifold forms a second surface surrounding an outlet. The sealing strand is disposed in a groove formed by one of the first and second surfaces. The groove has an inside surface. The first and second surfaces are pressed together to form a first seal. One of the first and second surfaces compresses the sealing strand against the inside surface to form a second seal. One of the first and second surfaces may be a convex surface. The other surface may be a concave surface.

Abstract: A refractory lining is formed in a furnace by providing a carrier for a lining form which has dimensions that provide a uniform space for the introduction of refractory material when the lining form is concentrically located within the furnace. The carrier concentrically engages and is attached to the lining form, and includes a portion that engages the furnace and locates the carrier and the lining form, when attached, concentrically within the furnace to provide a uniform space therebetween. The carrier can also have an upper surface that slopes downwardly from adjacent its center to its periphery to convey particulate refractory material poured onto the surface into the space between the lining form and the furnace. Further, a fixture is provided to hold the lining form concentric while the particulate refractory material is compacted by vibration.
