International Classification:

US Classification:
60286, 60274, 60285, 60288, 60311
Abstract:
A method for controlling diesel engine emissions is disclosed. The diesel engines exhaust system has a diesel particulate filter (DPF) and a lean NO trap (LNT). The DPF is a filter and 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 DPF to provide richer or hotter exhaust to the LNT. The sensor outputs and controls for providing the appropriate heat or fuel mix for regeneration and desulfurization may be controlled with enhancements to existing engine control circuitry.

Abstract:
A method for controlling diesel engine emissions is disclosed. The diesel engines exhaust system has a NO oxidation catalyst, a diesel particulate filter (DPF), and a lean NO 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.
Noreduction System For Diesel Engines, Using Hydrogen Selective Catalytic Reduction

International Classification:
B01D 53/34
US Classification:
422168
Abstract:
An emission control system for reducing NOin the exhaust of a diesel engine. A partial oxidation system receives diesel fuel from the engine's fuel tank and partially oxidizes the diesel fuel into hydrogen. The hydrogen is then introduced into the main exhaust line and the hydrogen-enhanced exhaust is delivered to a hydrogen selective catalytic reduction unit, which uses the hydrogen to convert the NOto nitrogen.

US Classification:
12356812, 606052
Abstract:
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.

Abstract:
An emission control system for reducing NOin the exhaust of a diesel engine. A partial oxidation system receives diesel fuel from the engine's fuel tank and partially oxidizes the diesel fuel into hydrogen. The hydrogen is then introduced into the main exhaust line and the hydrogen-enhanced exhaust is delivered to a hydrogen selective catalytic reduction unit, which uses the hydrogen to convert the NOto nitrogen.
Various methods and systems for augmenting the amount of NOin the exhaust of an exhaust flow simulation system. These methods and system can be “combustion” or “post combustion”. A combustion embodiment injects a nitrogen-containing compound (doping agent) into the burner, so that it mixed and combusted with the fuel.

Abstract:
An emissions control system is disclosed. The emissions control system may have a power source that creates a flow of exhaust and a filtering device that receives the flow of exhaust. A first sensor may be located at or upstream of the filtering device, the first sensor being configured to measure a first temperature, and an SCR catalyst may be located downstream of the filtering device. The emissions control system may also have an injector configured to inject a reduction agent into the flow of exhaust in the presence of the SCR catalyst. The emissions control system may further have a controller in communication with the first sensor. The controller may be configured to predict a change in an ability of the SCR catalyst to store reduction agent using a measured change in the first temperature and adjust the injector according to the predicted change in the storage ability of the SCR catalyst.
