Abstract

A fuel injection control system for a diesel engine is configured to, during one combustion cycle, perform multiple fuel injections to induce multiple combustions in a cylinder. A PCM controls fuel injection of the diesel engine. The PCM is configured to execute control for: at a first timing during compression stroke, starting a first fuel injection; a second timing during the compression stroke at which a time period corresponding to a first crank angle period has elapsed after a completion of the first fuel injection, starting a second fuel injection; and, at a third timing approximately a top dead center of the compression stroke at which a time period corresponding to a second crank angle period has elapsed after a completion of the second fuel injection, starting a third fuel injection. The second crank angle period is less than the first crank angle period.
