Abstract
An engine combustion control method may include: determining, by a controller, whether a fuel injection timing of an engine matches with an engine running condition of the engine; performing, by the controller, when the fuel injection timing matches with the engine running condition of the engine, a fuel injection variable establishment control (or a variable control of a fuel injection timing) that performs a Wavelet process on a frequency band selected by matching a vibration frequency of a vibration sensor signal to an engine frequency transformed under an engine running condition; and when the fuel injection timing matches with the engine running condition, updating a fuel injection parameter by correcting a target value of a combustion factor based on the fuel injection timing.
