Title: Operation of nitrogen oxides storage catalyst treating exhaust from lean burn engine, measures downstream exhaust gas oxygen concentration in strategy determining useful capacity to optimize rich regeneration extent
Inventor: ZHANG HONG
IPC: F02D41/14
Filed: 1999-10-26
Granted: 2000-12-07
Abstract: Nitrogen oxides (NOx) are stored during lean burn running with weak fuel/air mixture. The engine (1) is taken into the rich regeneration phase briefly by the controller (2). During this phase rich regenerant mixture is supplied, converting the stored NOx. An exhaust constituent is measured (5) downstream of the NOx storage catalyst (3); the regeneration phase is concluded in accordance its concentration. Regenerant supplied during this phase is determined, until the constituent concentration falls below a threshold value. From the quantity of regenerant, the total storage quantity in the catalyst is determined. From this total quantity, an oxygen storage quantity is subtracted, determining the useful storage capacity for NOx. This NOx storage capacity is used to control subsequent operation of the NOx storage catalyst. Preferred features: The operation is carried out repeatedly, initiating regeneration when NOx storage capacity is about to be overloaded. Should NOx storage capacity fall below a minimum value, the NOx storage catalyst is diagnosed as defective. The oxygen storage capacity is obtained from a performance characteristic limited by operational parameters. To determine the regenerant quantity, a mass flow rate dependent on an operational parameter is integrated. Behavior of the NOx storage catalyst during storage is modeled and matched with the NOx useful storage capacity. The constituent of exhaust gas which is measured, is the oxygen concentration.
