FIELD: mechanical engineering; two- stroke internal combustion engines. SUBSTANCE: injector has outer with mounting flange on its rear end, injection nozzle projecting from body at its front end, and fuel channel passing in center of injector. Spindle is installed from outer side of fuel tube and inside guide. Locking spring shifts spindle forward in direction of closing, and guide for spindle is pressed in injector body by means of stop bushing. Fuel tube is separate unit which is in contact with valve element arranged behind the unit through ring-shaped surface perpendicular to longitudinal axis of injector. Outer diameter of spindle front section is smaller than inner diameter of guide bore for spindle by μm, maximum. Inner diameter of spindle is greater than outer diameter of front part of fuel tube by μm, maximum. EFFECT: provision of more accurate control of sequence of injection and volumes of injected fuel. 12 cl, 1 dwg
