Carburetors are responsible for mixing air with fuel to obtain the correct ratio for a combustible vehicle’s engine. The carburetor also helps to control the engine’s speed when the gas pedal is pressed.
What is the need of carburetor?
A carburetor’s job is to supply an internal combustion engine with air/fuel mixture. Carburetors regulate the flow of air through their Main bore (Venturi), this flowing air draws in fuel and the mixture enters the engine via the intake valve.
What are all the functions of carburettor?
The main functions of a carburetor are
- The main function of carburetors to mix air and gasoline and provides a high combustion mixture.
- It controls the engine speed.
- It also regulates the air-fuel ratio.
- Increase or decrease the amount of mixture according to the engine speed and load changing.
What is the function of a carburettor in an engine?
Carburetor, also spelled carburettor, device for supplying a spark-ignition engine with a mixture of fuel and air. Components of carburetors usually include a storage chamber for liquid fuel, a choke, an idling (or slow-running) jet, a main jet, a venturi-shaped air-flow restriction, and an accelerator pump.
Who invented the carburetor?
What are the 3 types of carburetors?
There are three general types of carburetors depending on the direction of flow of air.
- Types of Carburetors.
- Constant Choke Carburetor:
- Constant Vacuum Carburetor:
- Multiple Venturi Carburetor:
What is the working principle of carburetor?
The carburetor works on Bernoulli’s principle: the faster air moves, the lower its static pressure, and higher the dynamic pressure is. The throttle (accelerator) linkage does not directly control the flow of liquid fuel.
What are the effects of knocking?
Knocking can cause overheating of the spark-plug points, erosion of the combustion chamber surface, and rough, inefficient operation.
What are the 3 things an internal combustion engine needs to run?
Beyond the combustion stroke, which pushes the piston down from the top of the cylinder, there are three other strokes: intake, compression, and exhaust. Engines need air (namely oxygen) to burn fuel.
What is the purpose of the choke?
A choke valve/cable is designed to restrict the flow of air in the carburettor of an engine. This helps enrich the fuel-air mixture, improving the ability to start an engine in low temperature conditions.
What is carburetor simple?
: a mechanical apparatus for premixing vaporized fuel and air in proper proportions and supplying the mixture to an internal combustion engine.
Where is a carburetor used?
Carburetor prepares a mixture of air and fuel (which is suitable for combustion) for an spark ignition engine. Carburetor is also used to control the speed of the vehicle. It converts petrol into fine droplets and mixes it in air in such away that it burns smoothly in engine, without any problem.
Why are carburetors not used anymore?
Most car manufacturers stopped using carburetors in the late 1980’s because newer technology was coming out, such as the fuel injector, that proved to be more efficient. There were only a few cars that continued to have carburetors, such as the Subaru Justy, until about the early 1990’s.
How do you clean a carburetor?

Where is the carburetor in a car?
The carburetor is a pipe above the engine cylinders with an air pipe and a fuel pipe connected to it. The air pipe brings in outside air, first through an air filter to remove dirt and other debris, and then to the carburetor. The carburetor, also known as the carb, has two valves that perfect the air to fuel ratio.
