FIELD: engines.
SUBSTANCE: invention may be used in internal combustion engines. Proposed is sprayer (1) for fluid medium injection into exhaust gas cleaning device (15), having injector (2), which is located in injector holder (3), wherein injector (2) has receiving opening (4) and injector holder (3) structural part (5) extends into receiving opening (4). Said sprayer (1) is suitable, primarily, for supply of urea aqueous solution into device (15) for vehicle (12) exhaust gas cleaning. Preferably, structural part (5) in longitudinal direction (23) is rigid, and compressed in radial direction (24) due to deformed rubber sheath (22) for compensation of solution volumetric expansion at its freezing.
EFFECT: injection of fluid medium into device.
