FIELD: mechanical engineering; engines; fuel injection equipment. SUBSTANCE: nozzle has body 1 divided into two parts one of which arranged in combustion chamber forms fuel metered amount space between side and end face walls. Ports 10 are made above this space in side walls, and throttling hole 9, in end face wall. With piston 13 moving upwards, pressure rises owing to considerable difference in areas of holes 9 and outer surface of fuel bath, and pressure is created forcing fuel through hole 9. Design of nozzle provides direct relation between pressure in combustion chamber and fuel delivery into combustion chamber. Use of catalytic attachment at fuel outlet from throttle hole is permitted. EFFECT: enlarged operating capabilities. 4 cl, 3 dwg
