Title: Diesel engine

Abstract: A dish-shaped combustion chamber (14) is formed in a diesel engine piston (13), and a fuel injector (16) is installed on the center axis of this combustion chamber (14). A device (3,41) is provided for varying the intake air amount aspirated into the engine. It is determined whether the engine is an idle running state or a normal running state. The device (3,41) is controlled so that the intake air amount in the idle running state is less than the intake air amount in the normal running state, and the injector (16) is controlled so that part of the fuel is injected before a main injection when the engine is in the idle running state.
