Fuel economy carburettor auxiliary air intake - is controlled by solenoid operated butterfly valve

摘要

The auxiliary air intake is positioned on the engine side of the carburettor designed to open whenever the accelerator pedal is rapidly depressed, the extra air intake ensuring a proper mixture at such times. The air intake is controlled by a solenoid, powered as a function of the accelerator depression. The solenoid core is rotated when energised, the rotation being transmitted to a butterfly valve (23) housed in a block attached to the carburettor outlet (2). The valve is positioned in line with the solenoid core, a bolt with a slotted head (26) passing through it from side-to-side. The valve is turned by the shaped end of the solenoid core engaging with the slot. The core also operates a switch supplying a dashboard lamp or lamps providing a monitor function.
