  • Internal combustion engine controller
    Patent number: 8374768
    Abstract: A controller of an internal combustion engine operable by an alcohol-containing fuel, includes: an alcohol concentration detecting unit, operable to detect an alcohol concentration of the alcohol-containing fuel; a feedback controller, operable to perform feedback control to make an exhaust air-fuel ratio of the internal combustion engine become equal to a target air-fuel ratio in accordance with an operation region; and an operation region setting unit, operable to set a stoichiometric operation region, in which the target air-fuel ratio is stoichiometric, in an enlarged manner when the alcohol concentration, detected by the alcohol concentration detecting unit, is higher than a concentration.
    Type: Grant
