Question:-
Compensating jet in carburetter supplies almost constant amount of petrol at all speeds because
Option (A)
The jet area is automatically varied depending on the suction
Option (B)
The flow from the main jet is diverted to the compensating jet with increase in speed
Option(C)
The diameter of the jet is constant and the discharge coefficient is invariant
Option(D)
The flow is produced due to the static head in the float Chamber
Correct Option:
(B)
Question Solution:
As the air flow increases the level in the fuel well decreases, thus reducing jet. The compensating jet thus tends toward leanness as main jet tends toward richness the sum of two remaining constant
