Solution:

The purpose of carburetion is to provide a combustible mixture of fuel and air in the required quantity and quality for efficient operation

QUESTION: 2

The petrol from tank to the automotive engine is fed by

Solution:
QUESTION: 3

The level of fuel in the float chamber of carburettor as compared to the level of the jet in the venture is

Solution:

To avoid overflow of fuel through jet, the level of the liquid in the float chamber is maintained at a level slightly below the tip of the discharge jet.

QUESTION: 4

Solution:
QUESTION: 5

All of the following carburettors are constant choke type except

Solution:

S. U. carburettor differs completely from all because it is constant vacuum or constant depression type with automatic variable choke.

QUESTION: 6

In passenger cars, the following type of carburettor is preferred

Solution:

Advantages of downward draught carburettor:
• No fuel lifting by air friction
• At low air velocity, fuel comes into cylinder by gravity
• High engine speed due to large mixing
• High specific output

QUESTION: 7

During idling state, gasoline does not flow through the carburettor tube because of

Solution:
QUESTION: 8

The float in the carburettor of a .petrol engine controls

Solution:

if the amount of fuel in the float chamber falls below the designed level, the float goes down, thereby opening the fuel supply valve and admitting fuel. So, float maintains a constant level of gasoline in the float chamber.

QUESTION: 9
