4. CATALYTIC CONVERTER
The multipoint system of injection of fuel (MSVT) is intended for an engine food by fuel in all conditions and power setting. Fuel arrives in the Engine through the nozzles located in the inlet pipeline about each cylinder.

The main sensor for MSVT is the sensor of concentration of oxygen (DKK) in the fulfilled gases of the engine. DKK is established in the final pipeline (collector). On signals of DKK EBU establishes amount of oxygen in the fulfilled gases and carries out regulation of structure of the toplivovozdushny mix arriving in the Engine. The optimum structure of a toplivovozdushny mix 1:14,7 provides the most effective work of catalytic converter and a minimum level of emission of harmful substances with the fulfilled gases. As DKK is included in a chain of feedback of EBU, a contour of management by structure of a toplivovozdushny mix fig. is closed. The closed contour of management of structure of a toplivovozdushny mix.
