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. The fuel injection control system comprises a PCM for controlling a fuel injection of the diesel engine. The PCM is configured to execute control for: at a first timing during compression stroke, injecting fuel in a first amount; at a second timing after the first timing and during the compression stroke, injecting fuel in a second amount greater than the first amount; and, at a third timing after the second timing and approximately a top dead center of the compression stroke, injecting fuel in a maximum amount greater than the first and second amounts.
