At inclusion of ignition ЭБУ includes an electrogasoline pump which creates pressure of fuel in a distributive highway. During the same time ЭБУ processes a signal from the gauge of temperature of a cooling liquid for definition of duration of impulses of injection necessary for start-up. When the cranked shaft of the engine at start-up starts to be turned, ЭБУ forms an impulse of inclusion of the atomizers which duration depends on temperature of a cooling liquid.

At start-up of the cold engine the injection impulse increases, atomizers open on больший a time interval and inject большее quantity of fuel (more sated working mix turns out).

At start-up of heated-up engine EBU having received the information on temperature of a cooling liquid, gives a command on closing of the established valve of stabilisation of idling, as a result duration of an impulse of injection decreases, and time of opening of atomizers is reduced to the nominal.

Idling the information on ЭБУ arrives from a potentiometer throttle заслонки, being in the case throttle заслонки, and the gauge of the mass expense of air. At decrease in frequency of rotation there is a change of the moment of ignition and duration of an impulse of injection owing to what the quantity of injected fuel increases increases.

At normal work of the engine position throttle заслонки and passing through the gauge of the mass expense of air quantity of let in air define duration of opening of atomizers and by that power setting.
