Title:
内燃機関の作動方法および内燃機関制御装置のための制御エレメント
Document Type and Number:
Japanese Patent JP4431242
Kind Code:
B2
Abstract:
The method of operating an internal combustion engine, especially of a motor vehicle, having a combustion chamber (4), which is operable in a plurality of combustion cycles, includes feeding an air mass (42) and a fuel mass (3) into the combustion chamber (4) in each combustion cycle; adjusting a mixture composition lambda (lambd) of the air mass to the fuel mass for one of the combustion cycles so that lambd>1; determining a residual air portion present in the combustion chamber (4) due to combustion occurring in the combustion chamber in the combustion cycle in which the mixture composition lambda (lambd) is greater than one; and reducing the air mass to be supplied to the combustion chamber (4) in another combustion cycle following the one combustion cycle in which lambd>1 by about the residual air portion found in the one combustion cycle. The portion of the residual air in the combustion chamber is exactly accounted for in determining fuel/air stoichiometry during combustion in this method so that engine operation and exhaust gas composition are improved. The invention also includes an control unit and/or control element of a control unit that is operable to perform this method.
