Estimating the term…
An internal combustion engine (1), in particular for a motor vehicle, is described, in which fuel may be injected into a combustion chamber (4) during an intake phase in a first mode of operation or during a compression phase in a second mode of operation, and in which exhaust gases may be sent to a catalytic converter (12). A control unit (18) determines a temperature difference between an actual exhaust gas temperature and a setpoint exhaust gas temperature at an operating point having a low exhaust gas temperature. In addition, at least one additional injection after combustion is implemented by the control unit (18) as a function of the temperature difference.
A method of operating an internal combustion engine (1), in particular of a motor vehicle, fuel being injected into a combustion chamber (4) of the engine (1) during an intake phase in a first mode of operation or during a compression phase in a second mode of operation, a catalytic converter (12) receiving the exhaust gases,
A control unit (18) for an internal combustion engine (1), for a motor vehicle in particular, fuel being injectable into a combustion chamber (4) during an intake phase in a first mode of operation or during a compression phase in a second mode of operation of engine (1), and a catalytic converter (12) being able to receive exhaust gases,
