  • Method for controlling an internal combustion engine in connection with an exothermal regeneration of an exhaust gas aftertreatment component
    Patent number: 9016049
    Abstract: A method is presented for controlling an internal combustion engine (10), which includes an exhaust gas system (12) having an exhaust gas aftertreatment component (22) that temporarily stores exhaust gas constituents and can be regenerated, wherein an expected value for a temperature of the exhaust gas aftertreatment component (22) is formed as a function of an increase in temperature, which arises as a result of exothermal reactions during the duration of an operating mode (BA2) of the internal combustion engine (10) which is set for the regeneration of said exhaust gas aftertreatment component (22), wherein the expected value is compared with an upper threshold value (T_max) and the control of said internal combustion engine (10) is changed when the threshold value (T_max) is exceeded, such that an expected value formed while taking the changed control into account does not exceed said threshold value (T_max).
