A method of controlling a diesel engine mounted in a motor vehicle and the diesel engine mounted in a motor vehicle

摘要

This disclosure provides a method of controlling a diesel engine that includes performing a premixed combustion pattern fuel injection including one or more injections at a first point in time while an amount of EGR gas is injected into one according to an operating condition of the engine Cylinder is injected when engine load is low to operate in a premixed combustion mode, performing diffusion combustion pattern fuel injection including one or more injections at a second point in time later than the first point in time when the engine load is high is to operate in a diffusion combustion mode and includes performing diffusion combustion pattern fuel injection at a third timing which is later than the second timing while the amount of EGR gas is introduced into the cylinder according to the operating condition of the engine when is switched from the diffusion combustion mode to the premix combustion mode with a decrease in engine load.
