Title: Exhaust air particulate treatment device for internal combustion engine
Inventor: SHINJO TAKASHI
IPC: F02D45/00
Filed: 2000-08-03
Abstract: PROBLEM TO BE SOLVED: To securely promote combustion of particulates by utilizing NO2 even in an operation condition in which exhaust air temperature becomes low. SOLUTION: Oxidation catalyst and a particulate catching filter are arranged in series in an exhaust passage of a diesel engine. Exhaust air particulates are trapped by the particulate catching filter. NO in exhaust air becomes NO2 due to oxidation catalyst, and combustion of particulates deposited by NO2 is promoted. Since a conversion rate into NO2 depends on exhaust air temperature, a fuel injection amount is increased, an air excess rate λ is reduced (step 5), and CO exhaust amount is increased when exhaust air temperature (t) is lower than exhaust air temperature Toxi at which a predetermined conversion rate is obtained (steps 4, 5). The CO is oxidized and reacted into CO2 in oxidation catalyst so that exhaust air temperature rises due to reaction heat and a NO2 conversion rate is increased.
