摘要： Reductant is metered into an engine exhaust gas after-treatment system upstream of an SCR catalyst at engine exhaust gas temperatures both less than and greater than a DEF dosing threshold temperature to render the catalyst effective in reducing NOx without creating undesired reaction products which would impair effectiveness of the after-treatment system at engine exhaust gas temperatures less than the DEF dosing threshold temperature.

摘要： An exhaust gas turbocharger housing (10) for an engine includes a main turbine housing portion (14) and a throat portion (12) defining an exhaust gas passageway (20) that is in upstream fluid communication with the main turbine housing. The exhaust passageway (20) communicates exhaust gases (EG) to the main turbine housing portion (14). A flow divider (22) generally bisects the exhaust gas passageway (20) forming a first inlet passageway (24A) and a second inlet passageway (24B). A flow hole (26) is disposed through the flow divider (22) for permitting the fluid communication of exhaust gas (EG) from the first inlet passageway (24A) to the second inlet passageway (24B).

摘要： A method for determining the degree of saturation of a solid ammonia storage material in a storage unit includes activating a heater to release ammonia from the storage material until the pressure of the storage unit reaches a predetermined pressure. The method then deactivates the heater and determining a decay rate of the pressure of the storage unit while the heater is deactivated. The method estimates the degree of saturation of the ammonia storage medium in response to the decay rate. According to some embodiments, determining the decay rate may include measuring the time required for the pressure of the storage unit to drop from a first pressure threshold to a second pressure threshold.

摘要： A method controlling operation of an engine utilizing a number of preset operating parameters is provided. An operating mode of the engine is determined. An operating state of the engine is determined. A first plurality of engine parameter settings are retrieved from a memory in response to the determined operating mode and the determined operating state of the engine. The first plurality of engine parameter settings are applied to at least one control algorithm of the engine. A rate of soot accumulation from the engine is monitored. The rate of soot accumulation is compared to a predetermined soot accumulation rate threshold. A second plurality of engine parameter settings are retrieved from a memory in response to the monitored rate of soot accumulation exceeding the predetermined soot accumulation rate threshold.

摘要： A method of operating the turbine booster to improve engine operating response and to increase the effectiveness of emission control devices is disclosed. A turbocharger turbine booster for a turbo charged internal combustion engine provides pressurized air to the turbocharger turbine and increases the oxygen in engine exhaust without increasing the engine combustion oxygen content.

摘要： A method for controlling an internal combustion engine (10) limits emission of undesirable compounds of nitrogen and oxygen and provides increased transient power, the method comprising: operating the engine at a first power output by providing a first air/fuel mixture to a combustion chamber of the engine; receiving a request for an increased power output from the engine, that is greater than the first power output; providing a second air/fuel mixture to the combustion chamber of the engine, the second air/fuel mixture comprising a greater amount of fuel than the first air/fuel mixture; and treating a flow of exhaust gas with a non-urea aftertreatment to reduce a level of pollutant in the exhaust gas during a fuel enriched operation of the engine to invoke the real-time removal reduction of the pollutant while increasing engine power.

摘要： The present technology provides one or more methods of operating an engine in a motor vehicle. In at least one embodiment, the existence of an engine idle condition is determined. The method may also include determining whether an operator is present in the vehicle. In some embodiments, the engine operates at a performance idle speed when an engine idle condition exists and an operator is present in the vehicle. In further embodiments, the engine operates at a fuel economy idle speed when an idle condition exists and no operator is present in the vehicle. In still further embodiments, the fuel economy idle speed will be lower than the performance idle speed. The present technology anticipates engine workload and controls engine idle speeds. Based on the anticipated workloads, the present technology can reduce engine stalling while also reducing emissions and increasing fuel economy.
