Operation Overview
The engine of a vehicle is operated under a wide range of
conditions, from idling with the throttle valve remaining
almost closed, to full load or maximum output with the throttle
valve fully opened. In order to meet the requirements for the
proper mixture ratio under these varying conditions, a low
speed fuel system, or pilot system, and a main fuel system are
provided in these type of carburetors.
The function of a carburetor is to produce a combustible
air/fuel mixture by breaking fuel into tiny particles in the form
of vapor, to mix the fuel with air in a proper ratio, and to
deliver the mixture to the engine. A proper ratio means an
ideal air/fuel mixture which can burn without leaving an
excess of fuel or air. Whether the proper mixture ratio is
maintained or not is the key to efficient engine operation.
This carburetor has varying operations depending upon
varying driving conditions. It is constructed of a float system,
pilot system, main system, and starter system or initial starting
device.
