The carburetor 2-ITS is the carburetor of the overturned type, two-step with electronic adjustment. This carburetor has no traditional auxiliary systems of the main fuel system, for example, of the equipment of work of start-up or the accelerating pump. Functions of these systems are performed by two regulators: regulator of position of the gate and 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 a lambda is in the forward muffler of system of an exhaust. It carries out measurement of content of carbon monoxide in exhaust gases and sends the corresponding signal (tension) to a control system. Thanks to it the equipment of management changes a ratio of fuel and air, soaked up in the carburetor, and thus optimalizirut burning conditions.
