- 5. A direct injection diesel engine according to claim 1, wherein
the cylinder head is fixed by use of cylinder head bolts disposed on a first side of the row of cylinders and cylinder head bolts disposed on a second side of the row of cylinders; and the second intake port extends toward the second intake opening from a space between two cylinder head bolts disposed on the first and second sides, respectively, of the row of cylinders.
- 6. A direct injection diesel engine according to claim 1, wherein the first intake port is formed parallel to a glow plug mounted on the cylinder head as viewed from the center axis of the corresponding cylinder.
- 7. A direct injection diesel engine according to claim 1, wherein the fuel injection element injects pressurized fuel into the combustion chamber.
