Document Type and Number:
Japanese Patent JP7430805
Kind Code:
B2
Abstract:
A method for operating an internal combustion engine of a motor vehicle, where the internal combustion engine includes a combustion chamber and a prechamber spark plug which is assigned to the combustion chamber and which has a prechamber which is fluidically connected to the combustion chamber via a plurality of openings. The method includes operating the internal combustion engine in a catalytic converter heating operation in which an ignition time, at which an ignition spark for igniting a fuel-air mixture in the combustion chamber is generated in the prechamber within a particular operating cycle of the internal combustion engine, is shifted later compared to a normal operation. An injection time, at which a last direct fuel injection into the combustion chamber is carried out within the particular operating cycle, is a same in the catalytic converter heating operation and in the normal operation.
