Title: Method of setting fuel/air mixture for internal combustion engine
Inventor: SCHNAIBEL EBERHARD
IPC: F01N3/20
Filed: 2002-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a method of compensating a fresh catalyst for the shift of air-fuel ratio in lean direction during the control of the air-fuel ratio for an internal combustion engine having a catalyst and tow-sensor control. SOLUTION: The method of setting a fuel/air mixture for the internal combustion engine 2 having the catalyst 8 and at least one exhaust gas sensor 12 positioned behind the catalyst for providing first information about the oxygen content of exhaust gas, which adjusts the setting of the fuel/air mixture, forms second information about hydrogen existing in the exhaust gas behind the catalyst, which adjusts the fuel/air mixture. The method compensates the undesirable influence of hydrogen on the setting of the fuel/air mixture which causes the hydrogen cross detectability of the exhaust gas sensor in relation to the detection of hydrogen and the generation of hydrogen behind the catalyst.
