Abstract
Previously the author investigated the relation between air swirl intensity and number of injection nozzle holes by a high speed 2 cycle uniflow scavenging type diesel engine. The fuel injection nozzle was mounted in the center of cylinder head and injected radially. The air swirl was produced by the inclination of scavenging ports. In this paper the anthor studied the relation between the engine performance and the direction of the sprays of 2 fuel injection nozzles mounted on the sides of cylinder head symmetrically. Test engine was the same as used in the previous experiment. The results show that the engine performance was good when the nozzle spray was injected in the same direction as the air swirl. The best angle β (see Fig. 1) of the spray was 30∼40°.
