Abstract
Method for detecting abnormal combustion, in particular combustion knock or pre-ignition, in at least one cylinder of an internal combustion engine, comprising a step of determining cylinder specific measurement data for each one of the at least one cylinder based on measurement signals acquired by at least one vibration sensor; a step of obtaining a cylinder specific detection configuration for each one of the at least one cylinder; and a step of analyzing, for each one of the at least one cylinder, the cylinder specific measurement data based on the associated detection configuration to detect an abnormal combustion condition.
Claims15
A method for detecting abnormal combustion, in particular combustion knock or a pre-ignition, in at least one cylinder of an internal combustion engine, comprising:
- a step of determining cylinder specific measurement data for each one of the at least one cylinder based on measurement signals acquired by at least one vibration sensor;
- a step of obtaining a cylinder specific detection configuration for each one of the at least one cylinder;
- and
- a step of analyzing, for each one of the at least one cylinder, the cylinder specific measurement data based on the associated detection configuration to detect an abnormal combustion condition.
A control unit of an internal combustion engine for detecting abnormal combustion, in particular combustion knock and/or pre-ignition condition, in at least one cylinder, wherein the control unit is configured for:
- determining cylinder specific measurement data for each one of the at least one cylinder based on measurement signals acquired by at least one vibration sensor;
- obtaining a cylinder specific detection configuration for each one of the at least one cylinder;
- and
- analyzing, for each one of the at least one cylinder, the cylinder specific measurement data based on the associated detection configuration to detect an abnormal combustion condition.
