摘要： A method for controlling diesel engine emissions is disclosed. The diesel engine's exhaust system has a NOx oxidation catalyst, a diesel particulate filter (DPF), and a lean NOx trap (LNT). The DPF is monitored to determine the need for regeneration. The LNT is monitored to determine the need for regeneration or desulfurization. A fuel injector is used to inject fuel upstream of the LNT under certain conditions, and a bypass may be used to bypass exhaust around the oxidation catalyst to provide richer or hotter exhaust to the LNT.

摘要： A method and system for controlling the temperature of recirculated exhaust gas in an exhaust gas recirculation (EGR) system, such as those used in connection with diesel engines. An EGR loop (which may be either a high pressure loop or a low pressure loop) has a dual-leg segment with an EGR cooler on one leg and an EGR heater on the other leg. By means of a valve, the EGR gas may be diverted to either one leg or the other, thereby providing either cooled or heated EGR gas to the engine.

摘要： A system is provided for rapidly changing the flow of recirculated exhaust gas to each cylinder of an internal combustion engine operating on diesel fuel or other fuels. The system preferably includes an exhaust gas recirculation line having an exhaust gas recirculation pump along with a reservoir and cooler for storing a desired volume of recirculated exhaust gas. Recirculated exhaust gas is preferably supplied from the reservoir to each cylinder of the associated engine through respective recirculated exhaust gas conduits. A metering valve is preferably disposed within each recirculated exhaust gas conduit immediately adjacent to each cylinder. The metering valves provide uniform distribution of recirculated exhaust gas to the respective cylinders and allow the system to rapidly change the flow of recirculated exhaust gas to each cylinder. The system provides recirculated exhaust gas at a point close to the combustion chamber where it is needed for effective reduction of undesirable NO.sub.x emissions.

摘要： A system for controlling exhaust gas recirculation flow rates and power augmentation of a turbocharged internal combustion engine operating on diesel fuel or other fuels. Exhaust gas from the engine's exhaust manifold is used to drive the turbocharger. Exhaust gas exiting from the turbocharger is directed through a filter trap. A first portion of the exhaust gas exiting the filter trap flows through an exhaust gas recirculation cooler to provide a first input to an electronically controlled diverter valve. Filtered intake air is supplied as a second input to the electronically controlled diverter valve. A mixed output of intake air and recirculated exhaust gas is directed from the diverter valve to an electrically driven compressor and then to the intake manifold of the diesel engine. The combination of the electronically controlled diverter valve and the electrically driven compressor controls both the exhaust gas recirculation flow rates and smoke limited power output at speeds below the peak torque speed of the associated engine. Above peak torque speeds, the turbocharger generally supplies all required intake air to the engine and the electrically driven compressor supplies only recirculated exhaust gas to control NO.sub.x emissions from the engine.

摘要： A method of reducing emissions by operating a diesel engine in a stoichiometric air-fuel ratio mode. To achieve an optimal stoichiometric mode, intake throttling, boost air intake control, fuel injection adjustments, and exhaust gas recirculation (EGR) are used.

摘要： A filtration system adapted to prevent diesel soot carried with recirculated exhaust gas from being recirculated through internal combustion engine. The filtration system provides continuous elimination of soot, thus reducing its negative impact on engine life, lubrication oil quality, and on components in the exhaust gas recirculation system. The filtration system comprises a non-thermal plasma generator that periodically, or continuously, oxidizes carbon deposited, or trapped, within a carbon filter disposed downstream of the non-thermal plasma generator.
