Abstract
A direct injection diesel engine includes a cylinder head which is formed, for each cylinder, with a plurality of intake ports. At least one of the intake ports has an approximately straight throat extending tangentially to the cylinder and opening into a combustion chamber at upper reaches of swirling. Another of the intake ports has a throat opening into the combustion chamber at lower reaches of swirling. A glow plug extends downward from one side of the cylinder head, at which the intake ports open, toward a location between the other intake port. An exhaust port extends from another side of the cylinder head and opens into the combustion chamber.
