Fuel atomizer МСВТ is intended for fuel giving in the inlet pipeline of the separate cylinder of the engine. Work of the electromagnetic valve of an atomizer operates ECU. The valve of an atomizer of spherical or needle type is executed normally closed. Fuel passes on channels in an atomizer, through обрытый the spherical or needle valve and through apertures распылительной plates is injected into the pipeline, fig. the Fuel atomizer. In распылительной to a plate it is executed six apertures, providing dispensing of a stream of fuel and formation конусного a torch it is thin the sprayed fuel in сопловой parts of a tip of an atomizer. From a tip of an atomizer fuel arrives in the inlet pipeline where there is a further dispersion and fuel evaporation before всасыванием in the cylinder. The atomizer with not tight valve causes pressure drop in fuel system after engine deenergizing. In certain cases this defect is shown in the complicated start-up of the engine (long rotation of a cranked shaft by a starter is necessary). Besides, small receipt of gasoline through not tight valve of an atomizer leads to engine work at калильном ignition after deenergizing of the lock of ignition.
