FUEL AND LUBRICATION SYSTEM 4-4
DIAPHRAGM AND PISTON OPERATION
The carburetor is a variable-venturi type, whose venturi cross section area is increased or decreased
automatically by the piston according to the vacuum present on the downstream side of the venturi.
Vacuum is admitted into the diaphragm chamber through an orifice provided in the piston.
Rising vacuum overcomes the spring force, causing the piston to rise to increase the said area and thus
prevent the air velocity from increasing. Thus, air velocity in the venturi passage is kept relatively constant
for improved fuel atomization and for securing and optimum ratio of fuel to air in the mixture.
