Method and device for controlling combustion process of diesel engine

The invention discloses a control method and device for the combustion process of a diesel engine. The combustion process control method comprises the steps that target combustion characteristic parameters are obtained; obtaining current combustion characteristic parameters of the diesel engine; wherein the combustion characteristic parameters comprise at least one of a combustion rate parameter and an explosion pressure parameter; oil injection parameters of the diesel engine are adjusted according to the current combustion characteristic parameters and the target combustion characteristic parameters, so that the difference value between the current combustion characteristic parameters and the target combustion characteristic parameters is within a preset range; wherein when the target combustion characteristic parameters comprise the target combustion rate parameter, the fuel injection parameters comprise the fuel rail pressure and the sequential injection time, and when the target combustion characteristic
