摘要： An injector cleaning system (13) for use with an exhaust treatment device is disclosed. The injector cleaning system may have a supply of injection fluid (64) and an injector (52) configured to receive and inject the injection fluid. The injector cleaning system may also have a pressure sensor (60) associated with the injector to generate a signal indicative of the pressure of the injection fluid supplied to the injector. The injector cleaning system may further have a controller (62) in communication with the injector and the pressure sensor. The controller may be configured to determine a pressure decay rate of injection fluid supplied to the injector during a normal injection event based on the signal. The controller may be further configured to compare the determined pressure decay rate to an expected pressure decay rate, and supply cleaning fluid to the injector based on the comparison.

摘要： A pre-chamber (120) for a fuel injector (112) is disclosed. The pre-chamber (120) includes a cylindrical body member (140) extending axially from a first end portion (146) to a second end portion (148) opposite to the first end portion (146). The pre-chamber (120) further includes a bottom plate (142) located proximal to the first end portion (146) of the cylindrical body member (140). The pre-chamber (120) also includes a sacrificial member (144) extending axially outwards from the second end portion (148) of the cylindrical body member (140).

摘要： A method of remanufacturing a prechamber assembly includes determining a width W of an original circumferential weld bead (50) that extends around and joins a proximal end of an outer peripheral wall of a prechamber housing (30) and a distal end of an outer peripheral wall of a body assembly (20), cutting through the weld bead (50) in order to separate the prechamber housing (30) from the body assembly (20), and removing material from an outer peripheral portion of a distal end portion of the body assembly (20). The method includes removing the material in an axial direction parallel to the central axis of the prechamber assembly for a distance that is from 2.5 - 3 times the width W.

摘要： A method for manufacturing an engine block (10) includes removing material from the top deck (18) of the engine block (10) surrounding a first opening to create a first recessed area (22), placing a first seal (90) within the first recessed area (22), positioning a first insert (50) within the first recessed area (22) and against the first seal (90). The method may also include removing material from the top deck (18) of the engine block (10) surrounding a second opening to create a second recessed area (70) that at least partially overlaps the first recessed area (22), placing a second seal (95) in the second recessed area (70) and positioning a second insert (78) within the second recessed area (70) and against the second seal (95).
