Title: Exhaust emission control device for internal combustion engine
Inventor: SUGURO HAJIME
IPC: F02D43/00
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To prevent an after projection fuel for supplying hydrocarbon to a NOx catalyzer from adhering to a cylinder wall for getting mixed in a lubricating oil. SOLUTION: Inside temperature and inside pressure are presumed from an engine operation condition and an after injection time, and the lower limit setting value and upper limit setting value of the after injection quantity are computed from the result of above presumption (step 106, 107). In the case where the after injection quantity Y1 per cylinder computed from an engine operation state and an catalyzer temperature is smaller than the lower setting value, the after injection is stopped to integrate the after injection quantity for several cycles, and when the integrated value X becomes more than the lower limit setting value, the number of after injection cylinders is computed on the supply quantity of light oil per unit time Z and the number of revolutions of an engine, and the after injection quantity Y per cylinder (per stroke) is therefore computed (step 108-110).  In the case where the after injection quantity Y is larger than the upper limit setting value, the after injection quantity Y is corrected to the upper limit setting value, and then the after injection is carried out (steps 111, 112, 113).
