Title: Air fuel ratio control system for engine with oxidation- and nitrogen oxides storage catalysts
Inventor: YAMASHITA YUKIHIRO
IPC: F02D41/14
Filed: 1999-04-26
Abstract: Engine lean burn operation alternates with NOx catalyst rich regeneration. A sensor (27) upstream of the NOx catalyst (14) in the exhaust pipe (12) measures exhaust oxygen concentration. A controller (30) controls rich combustion and degree of enrichment of exhaust gases for reaction in the NOx catalyst, by monitoring the signal from the oxygen concentration sensor (27) Preferred features: The catalyst (13) upstream of the oxygen concentration sensor (27) has oxygen storage capacity. There is a further catalyst (not shown) upstream of the sensor and NOx catalyst, with small oxygen storage capacity. An NOx computer (31) determines NOx adsorbed in the catalyst (14). A computer (31) determines a reference rich quantity on the basis of the calculated quantity of  NOx adsorbed in the NOx catalyst. The control unit (30, 31) determines combustion of the rich mixture corresponding to the calculated reference amount. The quantity of rich components accumulated is determined from the oxygen sensor output. Rich combustion is continued until the value reaches the reference amount for rich components. The controller calculates an interval from the oxygen sensor, required to vary air fuel ratio to a rich value exceeding stoichiometric, during rich combustion. Rich combustion is continued until the computed reference quantity of rich components has been reached. In a similar operation, the time and quantity criteria can be combined.
