Abstract

DC60 Electronic control system for carburettors. Includes 24, 25 transmission devices that have been linked with valves 7, 8, electric actuators 20, 21 for driving valves 7, 8 and control units. Electronic 12a for controlling electric actuators 20, 21, transmission devices 24, 25, electric actuators 20, 21 and electronic control units 12a are packed in 10 housings mounted on the C trajectory carburetors. Ventilation 72, 74, 74 ', 89, 90 for making 10 inside of the housing contact with the outside. It has been connected to the housing 10, therefore it is possible to effectively pack the transmission device, the electric actuator and the electronic control unit in the same housing to reduce the size. Electronic control system for carburettors. And thus the durability of the control unit electronics And better electric drive The electronic control system for the carburettor consists of 24, 25 transmission devices linked with valves 7, 8, electric actuators 20, 21 for driving valves 7, 8 and electronic control units 12a for controlling the operation of the electric actuators 20. , 21 Transmission devices 24, 25, electric actuators 20, 21 and electronic control units 12a are packed in housings 10 installed on the carburettors C ventilators 72, 74, 74 ', 89, 90. For making the inside of the housing 10 contact with the outside Has been connected to the aforementioned 10 housings, therefore it is possible to contain the transmission equipment Electric actuator and electronic control unit Effectively in the same housing to reduce the size of the electronic control system for the carburettor and make Provides better durability of electronic control units and electric actuators
