Abstract
The present invention relates to a process for optimizing the combustion of an internal-combustion engine running under controlled self-ignition conditions, wherein the state of the combustion of an air/fuel mixture in combustion chamber ( ) is measured and, after processing the measuring signals sent to a logical processing unit ( ), at least one combustion control parameter is adjusted so as to obtain the desired combustion for the next cycles. The process includes several parameters to be adjusted are determined to optimize the combustion, said parameters are divided into fast parameters (PR) and slow parameters (PL), the fast parameters (PR) are managed by means of a control loop specific to said parameters and the slow parameters (PL) are managed by means of a control loop specific to the slow parameters to obtain the desired combustion for the next cycles.
