ABSTRACT:
A diesel engine has a cylinder head, an auxiliary combustion chamber defined in the cylinder head, an atomization passage communicating with the auxiliary combustion chamber, and a fuel injection nozzle means mounted in the cylinder head and having a primary injection port opening into the auxiliary combustion chamber and a secondary injection port opening toward an inner wall surface of the atomization passage. When the diesel engine is under a low load, fuel is injected from the secondary injection port toward the inner wall surface of the atomization passage while fuel is prevented from being injected from the primary injection port, for thereby causing fuel to flow along an inner wall surface of the auxiliary combustion chamber, which is positioned downstream in the direction in which a swirl flows.
