DDZ is established on the butterfly valve case from the opposite side from the lever of a drive of a zaslonka. DDZ is intended for transformation of an angle of rotation of a zaslonka to an electric signal which moves on EBU entrance. The provision of a butterfly valve is considered by EBU at determination of duration of a phase of opening of fuel nozzles. At complete opening of a butterfly valve of EBU provides the maximum supply of fuel through all four nozzles, increasing a phase of opening of nozzles or increasing frequency of operating impulses. DTsZ is connected to the butterfly valve roller, movement to which it is transferred from an accelerator pedal. For transformation of an angle of rotation of a butterfly valve to an electric signal the potentiometer which eats from EBU 5 V.Pri's basic tension turn of a zaslonka is used electric resistance of a potentiometer and tension of a target signal of DTsZ changes. On size of a signal of DTsZ EBU counts the current provision of a butterfly valve. |
