摘要： A method and apparatus for determining a leak in an HC fluid supply of an exhaust purification system for an engine is disclosed. The fluid supply includes an injector that injects an amount of a NOx reducing fluid, a tank that holds the NOx reducing fluid, and a pump that pressurizes the NOx reducing fluid. The system fluid pressure is read before and after the pump is shut off. The pressure readings are compared and the exhaust purification system is turned off in response to the difference between the pressure readings being greater than a predetermined value.

摘要： A modular catalytic converter and muffler is used to purify exhaust from a relatively large diesel engine. The device includes various structural components that are mounted in the exhaust flow path within a housing having an inlet and an outlet. A plate mounted within the housing divides the housing into an inlet chamber and an outlet chamber. A plurality of catalytic converter sub-cans are mounted across the plate between the inlet chamber and the outlet chamber. A flow distributor is mounted within the housing upstream of the catalytic converter sub-cans. The flow distributor divides and directs a portion of the exhaust to each of the catalytic converter sub-cans. Some muffler structure is mounted within the housing between the catalytic converter sub-cans and the outlet in order to attenuate noise in the exhaust.

摘要： The present invention is particularly well suited for purifying exhaust from relatively large lean burn diesel engines. The emissions purification system causes the addition of an optimal amount of fuel through the engine fuel injector after closure of the fuel injector needle check valve by enlarging the fuel injector SAC volume. The optimal amount corresponds to an amount that will achieve optimal NOx reduction rates for the given engine operating condition and exhaust temperature when the exhaust is passes through appropriate deNOx and oxidation catalysts located downstream from the injector. The emissions purification system of the present invention has the ability to greatly reduce NOx content of the exhaust while maintaining HC emissions at acceptable levels and greatly reducing system complexity.

摘要： The present invention is particularly well suited for purifying exhaust from relatively large lean burn diesel engines. The emissions purification system causes an after-injection of fuel through the engine fuel injector during the exhaust stroke of an internal combustion engine. A computer controls the injector to inject an optimal amount of NOx reducing fuel into the engine cylinder. The optimal amount corresponds to an amount that will achieve optimal NOx reduction rates for the given engine operating condition and exhaust temperature. A computer periodically senses the engine operating condition and determines the exhaust temperature, and calculates the appropriate injection amount. With appropriate deNOx and oxidation catalysts located downstream from the injector, the emissions purification system of the present invention has the ability to greatly reduce NOx content of the exhaust while maintaining HC emissions at acceptable levels and greatly reducing system complexity.

摘要： The present invention is particularly applicable to lean burn engines that produce exhaust containing insufficient amounts of unburned hydrocarbons to satisfactorily reduce NOx emissions without undermining engine performance. In the exhaust purification system, ethanol or another suitable hydrocarbon is injected into the exhaust stream at an appropriate location between the engine and the catalytic converter. A deNOx catalytic converter is positioned within the exhaust downstream from the ethanol injection point. The combination engine application, ethanol injection and suitable deNOx catalyst combine to reduce NOx to satisfactory levels without producing significant amounts of undesirable secondary nitrogen containing compounds. An oxidation catalytic converter is positioned in the exhaust downstream from the deNOx catalytic converter. The oxidation catalyst serves to convert any remaining unburned hydrocarbons into carbon dioxide and water. At the same time, only small amounts of secondary nitrogen compounds are converted back into NOx compounds upon passage through the oxidation catalyst. The end result being an over all reduction in both HC and NOx compounds particularly for lean burn engines to satisfactory levels.
