Patent abstract
During high-load operation of an engine, fuel for initial slow-burning combustion and premixed combustion is injected into a combustion chamber by continuous fuel injection, then fuel injection is paused, and fuel for diffusion combustion is injected after a predetermined interval has elapsed. Also, the fuel injection amount in the continuous fuel injection is set higher than the fuel injection amount for diffusion combustion. A spray autointerference cooling effect is achieved by the continuous fuel injection, thus promoting ignition delay so as to increase the proportion of premixed combustion, thereby suppressing the production of smoke. This enables high-volume EGR to be performed, thus enabling reducing the amount of NOx produced.
