Carburettor slow running jet control - has solenoid valve to close orifice when engine is braking vehicle

Abstract

Abstract The carburettor of a vehicle engine has a solenoid operated valve (1') in the fuel passage to the slow running jet. The solenoid can be energised by a contact (6') operated by the accelerator pedal. A parallel circuit energises it through a relay (8') which is normally closed and is opened by a tachometer (9') when the engine speed exceeds a preset minimum. At low speed, the valve is kept open by the tachometer. At high speed it closes if the accelerator is released to slow the vehicle down. The system thus shuts theslow running jet when the engine is braking the vehicle. A manual switch (7') can keep the valve permanently open.
