    摘要: A diesel locomotive engine (10) having a combustion chamber (30) formed into the cylinder head (16) to have a diameter (D2) greater than the diameter (D1) of the cylinder liner (14). A piston (20) is disposed for reciprocating motion in the cylinder. The piston has a top wall (36) with a convex surface to form a generally ring-shaped combustion volume. A fuel injection nozzle (28) directs a flow of fuel into the combustion chamber in a direction generally along a radius of the generally ring-shaped combustion volume at a pressure of more than 1800 bar in one embodiment. A cooling passage (42) is formed in the cylinder head to remove heat energy, thereby reducing the production of the oxides of nitrogen during engine operation.
