This process is mainly used in a region where Air fuel ratio is low, so it is used Only in petrol engine.It is not used in diesel engine because,the diesel engine uses fuel injector which injects the diesel in high pressure to cylinder.
Carburetor is a device which mixes air and fuel in an appropriate proportion for the combustion process to happen.It mainly does 2 processes.
-Atomization and vaporization
let us take an example to understand atomization... If food has to be digested it should be broken down by chewing and then digested.Similarly if a liquid fuel has to be used properly the breaking of fuel is necessary to make sure that it mixes with air properly.
Vapourization- As the name indicates, it is a changes the fuel from liquid to vapour.
Now let us learn about the parts of a carburetor
Float and Float chamber:As we know the main function of a carburetor is to mix the air and fuel in proper proportion,if that has to happen the carburetor must be have a fuel chamber in which fuel is stored from main fuel tank at proper level and send the correct amount of fuel to further processing. For example, When the load in engine is less the fuel level in float chamber increases and when load in engine is more, the fuel level drops in float chamber.
Fuel Nozzle: The requrired amount of fuel to mix with air is given by this nozzle.
Venturi: Like how there is controller of fuel to carburetor, the air mixing with the fuel has to be controlled, that job is done by a venturi. It is a narrow passage from which air flows to mix with fuel and send the air fuel mixture to engine.In this part there is a narrow section where the velocity of air increases and hence it mixes with the fuel in correct proportion.
Throttle valve: After mixing the air and fuel it has to be sent into engine properly,that's the role of Throttle valve.It controls the air fuel mixture sent into the engine.
Choke Valve: During cold whether you might have experienced starting trouble in a vehicle. At that time we open the choke knob of vehicle and try to start, that time, the vehicle starts, so this provides extra rich mixture of fuel to engine. This enriches the fuel sent to engine.
We know how an car runs but getting into the details in depth is always intresting.. Stay connected with this blog for further information.
