Title: Air/fuel ratio control device for internal combustion engine
Inventor: OKADA KOJIRO
IPC: F02D41/06
Filed: 2001-03-22
Abstract: PROBLEM TO BE SOLVED: To provide an air/fuel ratio control device for an internal combustion engine, achieving an effective lean air/fuel ratio while maintaining control stability by performing lean burn limit control in consideration of the volatility of a fuel. SOLUTION: In the internal combustion engine having a lean burn limit control mode, when combustion stability detecting means 45 detects the combustion stability of the internal combustion engine and fuel property detecting mean 46 detects the volatility of the fuel to be supplied to the internal combustion engine, air/fuel ratio control means 42 makes an air/fuel ratio lean if the combustion stability detected by the combustion stability detecting means 45 is higher than a predetermined reference during the lean burn limit control of the internal combustion engine. At this time, the air/fuel ratio control means 42 makes a change into lean burn slower depending on how low the volatility of the fuel detected by the fuel property detecting means 46 is.
