摘要： A drive axle system can be converted between a single drive tandem axle arrangement including a rear drive axle a dual drive tandem axle arrangement. A forward bowl is provided for a forward axle system. One of a geared forward carrier and an ungeared forward carrier is mounted on the forward bowl, depending upon whether a dual drive or a single drive tandem axle arrangement is desired. To convert to the other type of tandem axle arrangement, the one of the geared forward carrier and the ungeared forward carrier is removed from the forward bowl and replaced, with the other one of the geared forward carrier and the ungeared forward carrier.

摘要： A method for operating an exhaust aftertreatment system injector to prevent coking includes steps of injecting fuel for heating the aftertreatment devices, when not injecting fuel, flowing air to purge and cool the nozzle to prevent carbon deposits when exhaust gas temperature is low, and substantially stop air flow to allow passive heating of the nozzle by the exhaust for oxidation of any accumulated carbon when exhaust temperature is high enough to support oxidation. Preferably, the nozzle has a catalytic material coating to reduce the temperature necessary for oxidation of the coking material.

摘要： Components in an exhaust after treatment system (EATS) for a diesel engine are monitored by measuring heat released (QDOC) across a diesel oxidation catalyst (DOC) and heat released (QEATS) across the DOC and a diesel particulate filter (DPF) during an A Hi injection event, by calculating heat input from AHI fuel (QAHI) during performance of the AH I injection event with a fully functioning AHI nozzle, and by measuring NOX conversion efficiency (nSCR) from NOX to N2 by a selective catalytic reduction system (SCR) at a condition where a SCR is sensitive to feeding gas compositions while AHI is not in use. Malfunctioning components are identified using these measurements and calculations.

摘要： Methods and systems for controlling reductant levels in an SCR catalyst are provided. In one aspect, reductant levels are adjusted in response to a ratio of change of NOx conversion efficiency to a change of reductant level. In another aspect, reductant injection levels are periodically adjusted to see if NOx conversion efficiency is better or worse at the adjusted levels.

摘要： In a method of monitoring an engine starting system in an engine, the engine starting system includes a charging system, a battery, a starter, a flywheel, and a controller. The controller and monitors can monitor components and systems associated with starting of an engine, such as engine or cranking speed, power cylinder unit compression, injection timing, and proper fuel delivery to predict and/or diagnose problems. For example, a charging system voltage is monitored and the charging system voltage is compared with predetermined charging system voltage values. Voltage of the battery is monitored and battery voltage is compared with predetermined battery voltage values. A signal to an operator is provided if one or more of the charging system voltage and the battery voltage are outside of predetermined ranges for the one or more of the charging system voltage and the battery voltage.
