Abstract (en)

[origin: EP2639433A1] The method (4) involves determining measure of risk of premature ignition (1) of a portion of a combustion chamber. Measurement of the surface temperature is determined (2) as measure of the risk of the premature ignition for subsequent or later cycle and compared with a predetermined limit value. Alternation in an operating parameter of a drive train is initiated (3) for non-compliance with a threshold value (5) for a preceding cycle in current or following working phase. The parameter of fuel quality is determined from evaluation of activity of knocking control. An independent claim is also included for an engine control equipment.
