Idling Devices of Automobile | Idling Devices in Carburetor | Anti-Dieseling Device

Idling devices in carburetor During idling, the throttle plate is almost in the closed position. Then the mass rate of air flow through the venture is small. Hence, the vacuum or depression produced at the venture is also small. With this small depression, no fuel can issue from the fuel orifice. Hence, an idling device…
