Embodiment Construction
[0030] The method according to the invention relates to a method of combustion control of an internal combustion engine which takes into account the phenomenon of knocking. The method includes estimating the engine knock intensity by processing the signal sent by the sensor, and the signal has physical meaning for directly qualitative combustion and possible occurrence of knock. The method is independent of the nature of the combustion and the cylinder pressure sensor technology used.
[0031] The present invention is described in terms of a specific embodiment, where the method is described as applied to a single cylinder, and does not contain specificities associated with the combustion mode of the engine. According to this embodiment, a cylinder pressure sensor is used. The nature of the internal combustion engine and the cylinder pressure sensor technology used do not affect the principle of the method.
