The multidot system of injection of fuel (МСВТ) is intended for a food of the engine by fuel in all conditions and power setting. Fuel arrives in the Engine through the atomizers located in the inlet pipeline about each cylinder.

The basic gauge for МСВТ is the gauge of concentration of oxygen (ДКК) in the fulfilled gases of the engine. ДКК it is established in the final pipeline (collector). On signals of DKK ECU establishes quantity of oxygen in the fulfilled gases and carries out structure regulation топливовоздушной a mix arriving in the Engine. The optimum structure топливовоздушной mixes 1:14,7 provides the most effective work каталитического neutralizer and a minimum level of emission of harmful substances with the fulfilled gases. As ДКК it is included in a chain of feedback ECU, a contour of management by structure топливовоздушной mixes fig. the Closed contour of management of structure топливовоздушной mixes is closed.
