Question

Which device mixes air and petrol (gas) for the internal combination engine?; 1) Carburetor; 2) Choke; 3) Crankshaft; 4) Cylinder

Answer 1

Hey.


Here is the answer.

The aix-fuel mixture is made in the carburetor of an internal combustion engine.


Air comes through the inlet into it and fule is injected by a nozzle making it into fine droplets for proper mixing.

The valve then put the mixture of air and petrol into the cylinder and rest compression and combustion takes place further.


So, Answer : (1) Carburetor


Thanks

Answer 2

Answer:

Carburettor mixes air and petrol (gas) for the internal combination engine. (Option 1)

Explanation:

• The term carburettor is sometimes shortened to carb in the UK and to carby in North America, colloquially.
• Carburation is the process of preparing a combustible fuel-air mixture by mixing the proper amount of fuel with air and discharging it into the engine cylinder.
• The device which performs this job is called a carburettor.
• The carburettor regulates the flow of air through the main bore.
• The air flowing in fuel and the mixture enters the engine through the intake valve.
• The carburettor works on Bernoulli’s principle; that is, when air moves faster, there will be lower static pressure, which results in higher dynamic pressure.
