Filed: 2002-05-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of determining the malfunction of an exhaust gas recirculation control device wherein the malfunction is flexibly and properly determined according to the exhaust characteristics of an internal combustion engine.   <P>SOLUTION: A controller for the exhaust gas recirculation control device compares the actual air intake GN to a given amount GNC1 when the engine is in stable idling (step S100 and S110). On condition that a state in which the actual intake GN exceeds the given amount GNC1 has lasted for a predetermined time (step S120 and S130), the controller determines that the amount of exhaust gas recirculation by the exhaust gas recirculation control device tends to be less than a standard amount corresponding to the stable idling state, and sets a recirculation exhaust gas deficiency flag XS to 'ON' (step S140). On condition that the recirculation exhaust deficiency flag XS is set to 'ON', the controller eases requirements for determination of the malfunction so as to reduce the chances of determining that there is a malfunction.  <P>COPYRIGHT: (C)2004,JPO
