    摘要： Exhaust flow from an internal combustion engine is divided in a predetermined ratio between two adsorber catalysts arranged in parallel during lean operation. A regeneration cycle time is predetermined and regeneration is accomplished by injecting hydrocarbons into a catalyst leg having a reduced exhaust flow. Upon regeneration of the catalyst, the exhaust gas flow distribution is reversed and the opposite catalyst is regenerated while the regenerated catalyst bears the brunt of the exhaust flow. The exhaust flow then reverts to a normal (e.g. 50—50) flow distribution until another regeneration cycle is warranted. A catalytic soot filter placed upstream of each adsorber is also regenerated by hydrocarbon injection. The addition of the catalytic soot filter provides more time and surface area for the hydrocarbon to react with the oxygen. Some of the diesel fuel is reformulated into hydrogen and carbon monoxide for superior regeneration.

    摘要： The present invention provides for adsorber catalysts arranged in parallel. The exhaust flow from the engine is divided in a predetermined ratio between the two catalysts during lean operation (e.g. 50-50). At a predetermined regeneration time (for example, when the adsorber catalyst is 20% full), the exhaust gas flow is reduced through the parallel leg that is to be regenerated (e.g. 20-80). A quantity of hydrocarbon is injected into the reduced-flow leg in order to make the mixture rich. Once the leg has been regenerated, the flow distribution between the parallel legs is reversed, and the other catalyst leg is regenerated while the other side (which is now clean) receives the majority of the exhaust flow. Once both catalyst legs have been regenerated, the exhaust flow is adjusted back to normal (e.g. 50-50) until the catalysts are again ready for regeneration and reduction. A catalytic soot filter is positioned downstream from the adsorber. The heat generated by the regenerating adsorber is transferred downstream to the soot filter, thereby heating the soot filter above the temperature required for regeneration. Additionally, any hydrocarbon that slips through the adsorber is burned in the catalytic soot filter, further raising the temperature. Such burning of the hydrocarbon slip in the catalytic soot filter obviates the need for a diesel oxidation catalyst, thereby reducing system cost and package size.

    摘要： The present invention provides for an NOx adsorber aftertreatment system for internal combustion engines which utilizes adsorber catalysts arranged in parallel. The exhaust flow from the engine is divided in a predetermined ratio between the two catalysts during lean operation (e.g. 50-50). At a predetermined regeneration time (for example, when the adsorber catalyst is 20% full), the exhaust gas flow is reduced through the parallel leg that is to be regenerated (e.g., 20% through the leg to be regenerated, 80% of the flow to the other leg). A quantity of hydrocarbon is injected into the reduced-flow leg in order to make the mixture rich. Since the flow has been reduced in this leg, only a small fraction of the amount of hydrocarbon that would have been required to make the mixture rich during full flow is required. This will result in a substantial reduction in the fuel penalty incurred for regeneration of the adsorber catalyst. Once the leg has been regenerated, the flow distribution between the parallel legs is reversed, and the other catalyst leg is regenerated while the other side (which is now clean) receives the majority of the exhaust flow. Another advantage of the present invention is that since NOx is being stored in one leg while the other leg is being regenerated, the regeneration operation can be performed for a longer period of time, resulting in greater regeneration efficiency. Once both catalyst legs have been regenerated, the exhaust flow is adjusted back to normal (e.g. 50-50) until the catalysts are again ready for regeneration and reduction.

    摘要： An apparatus, system, and method are disclosed for determining a catalyst bed temperature. The method may include receiving a current fluid mass flow within an exhaust pipe and a total amount of unburned fuel available for catalytic combustion. The method may further include determining a plurality of fluid enthalpy values corresponding to various locations within the exhaust pipe. The method may continue with calculating an amount of fuel burned on an upstream catalyst based on the plurality of fluid enthalpy values, and determining an amount of fuel remaining that is available for combustion on a downstream catalyst. The method may determine a combustion efficiency of the downstream catalyst based on the temperature rise across the downstream catalyst, and an amount of heat generated within the downstream catalyst based on the combustion efficiency and the amount of fuel remaining that is available for combustion on the downstream catalyst. The method may conclude with determining a downstream catalyst bed temperature based on the net heat generation, the fluid mass flow through the downstream catalyst, and the thermal response of the downstream catalyst.

    摘要： A food winding apparatus, system, and method of forming a rolled food item utilizing a slotted spool or cup and a push plate to eject the rolled food item from the spool. A food winding unit utilizes a motor to rotate a slotted spool. The leading end of a supported strip of food is detected by a sensor and directed into the slot of a spool. A micro-controller triggers a motor in response to the sensor signal to rotate and form a rolled food item after a predetermined number of rotations. An actuator is activated to displace an ejection plate to eject the rolled food item from the slotted spool. The winding unit can be integrated into a system including an extruder to deposit food onto support strips, a series of conveyors, and a rotary knife to cut the supported strip of food into predetermined lengths suitable for being rolled into a food item by the winding unit.

    摘要： A system, method, and software that rapidly heats a diesel oxidation catalyst unit to an effective operating temperature at engine startup is disclosed. Upon ignition of an engine an electronic control unit is operable to lower a fresh air flow target value to a reduced fresh air flow target value as well as lower a valve opening limit of an exhaust gas recirculation valve to a reduced valve opening limit. The electronic control unit monitors a temperature value of a flow of exhaust entering the diesel oxidation catalyst unit until the temperature value reaches a first predetermined threshold value. After reaching the first predetermined threshold value, the electronic control unit causes the fuel system to set post-injection fueling to a predetermined post-injection fueling value until the temperature value of the flow of exhaust entering the diesel oxidation catalyst unit reaches a second predetermined threshold value.
