The carburettor 2 is the carburettor of the overturned type, two-step with electronic adjustment. This carburettor has no traditional auxiliary systems of the main fuel system, for example, the equipment of work of start-up or the accelerating pump. Functions of these systems carry out two regulators: a position regulator заслонки and a regulator of installation of a throttle. Regulators receive electric impulses from a microprocessor control system which is placed behind the hiding place case.

The probe лямбда is in the forward muffler of system of an exhaust. It carries out maintenance gauging oxide carbon in exhaust gases and sends a corresponding signal (pressure) to a control system. Thanks to it the management equipment changes a parity of fuel and air which is soaked up in the carburettor, and thus оптимализирует burning conditions.
