ゼル機関。 The negative pressure supply system, which operates the EGR valve that controls the exhaust gas returned to the intake system of a turbocharged diesel engine with negative pressure, delays the negative pressure supply in response to the boost delay of the supercharger that occurs during transient periods. What is claimed is: 1. A diesel engine with a turbo supercharger, characterized in that it is provided with a delay means for causing the
