Abstract

PURPOSE: This device indirectly detects the combustion condition in a combustion chamber to control the switching of a reduction gas adjusting valve and makes reduction gas feed quantity correspond to the nitrogen oxide quantity in exhaust gassrapidly and accurately, preventing the blow-off of the reduction gas to the air.
