摘要： A method of operating an engine includes igniting a combustible mixture in a combustion chamber of the engine, which produces exhaust gases. The exhaust gases are ejected into an exhaust manifold of the engine to create a primary exhaust stream. A portion of the exhaust gases is separated from the primary exhaust stream to create a secondary exhaust stream. Air and fuel are then mixed with the secondary exhaust stream to form a reformer feed mixture. The reformer feed mixture is reacted in a catalytic reformer to create a reformate exhaust stream, which is then mixed with an intake air stream to create a mixed air stream. The mixed air stream is the fed to the combustion chamber of the engine as the combustible mixture.

摘要： An exhaust purification system of an internal combustion engine comprising an exhaust treatment catalyst (13) arranged in an engine exhaust passage and a heat and hydrogen generation device (50) able to feed only heat or heat and hydrogen to the exhaust treatment catalyst (13). When the warm-up operation of the heat and hydrogen generation device (50) is completed and a reforming action by a reformer catalyst (54) becomes possible, if the temperature of the exhaust treatment catalyst (13) is a preset activation temperature or more, a partial oxidation reaction is performed at the heat and hydrogen generation device (50) and the generated heat and hydrogen are fed to the exhaust treatment catalyst (50). At this time, if the temperature of the exhaust treatment catalyst (13) is less than the preset activation temperature, a complete oxidation reaction by a lean air-fuel ratio is continued and a heat is fed to the exhaust treatment catalyst (13).

摘要： An aftertreatment device for reducing NOx, PM, HC, and CO generated by a compression-ignition engine. In this device, lean exhaust air generated in the engine is enriched using a reactor together with an oxygen sorption device according to a target deNOx efficiency value, and heat energy is recovered. The enriched exhaust gas then passes through an oxidation catalyst, where NOx is reduced with CO and HC. PM in the exhaust gas is further trapped in a DPF. To lower energy cost, an heat exchanger is used for more effectively heating the DPF during regeneration, and an exhaust gas compressor positioned upstream from the DPF is employed to control engine back pressure. When exhaust gas temperature is low, to regenerate the DPF with minimum energy consumption, an electrical heater is used to heat dosing fuel before it is mixed with exhaust gas, and a regeneration heating process is then jump-started.

摘要： A reducing agent supplying device includes a reaction container, an ozone generator, an air pump, an ozone-containing air pipe, a compressed air pipe, a switching device, and a switching controller. The reaction container defines a reaction chamber therein in which a reducing agent is reformed. The ozone generator generates ozone from oxygen in air. The air pump supplies air into the ozone generator. An ozone-containing air flows through the ozone-containing air pipe toward the reaction chamber. A portion of a compressed air flows through the compressed air pipe toward the reaction chamber. The switching device switches between an air pump mode, in which the ozone-containing air is supplied into the reaction chamber, and a supercharging mode, in which the compressed air is supplied into the reaction chamber. The switching controller controls the switching device based on a catalyst temperature, which is a temperature of the reducing catalyst, and an exhaust pressure, which is a pressure in the exhaust passage.

摘要： In situations where the demand for syngas is intermittent, a fuel processor is operated to provide a high absolute hydrogen and carbon monoxide production, rather than to give a high fuel-specific hydrogen and carbon monoxide production. When a syngas generator is operated to intermittently produce syngas, a heating process can be performed between periods of syngas demand in order to keep the fuel processor within a desired temperature range. The heating process can comprise various steps or events including performing a heating event, allowing a standby period, and/or performing a carbon conversion event. Carbon formed during the process of converting fuel to syngas can be advantageously converted to maintain the temperature of the fuel processor within a desired range in between periods of syngas demand. A predictive method can be employed to control at least a portion of the heating process.
