Working of Choke in Two Wheeler in Hindi | How Vehicle Starts by Pulling Choke?

A choke in a carbureted internal combustion engine (be it a 2-stroke or 4-stroke engine) is a “Valve” present in the carburetor, normally the valve is a butterfly type which on pulling can block (choke) the fresh air supply to the carburetor. The choke can be pulled directly if it is placed right on the carburetor and can be pulled via cable if the pull plug is featured elsewhere on the two wheeler.
The choke is normally used when the engine is failed to crank after couple of tries, the failure could be caused by ‘n’ number of reasons. It is also recommended by many manufacturers that one should use the choke to start the bike/scooter when it is getting started for the first time in a day (normally in morning time). In a nutshell the choke comes handy when the engine gives you starting trouble, especially when it is at a cold state.
The choke is a valve situated right at the body of the carburetor. It is placed in between the air intake from the air filter and the Venturi present in the carburetor. True to its name the “Choke” actually chokes the fresh air intake from the air filter to the carb. The shape of the choke valve is normally butterfly and when it is pulled, it rotates to block the passage of the air from both the sides with both of its wings.
Now what happens, in the absence of the air stream there creates a partial vacuum inside the carburetor which in turn draws extra fuel from the jet into the intake manifold. This is the reason you’ve always been told not to give acceleration (or twist the throttle) while the choke is pulled, because there is already extra fuel being drawn into the intake manifold due to the choke. If you further turn the throttle on, the system will be flooded with the petrol and it would cost you what is best known as “Over” state.
The extra atomized (vaporized) fuel drawn because of choke provides extra chance to the combustion system to get the engine started, as the every extra vaporized fuel particle adds extra chance to the system to get started. When the system is flooded with the pure atomized fuel, no matter if the particles are turned into droplets due to the cold state, there is an increased chance of a single particle to catch fire if squirted near to the sparkplug or at the right time, rest will be taken care by the Chain Reaction and the engine gets started lightning fast.

[@ayushmaansural4896]

Sir , Lets say choke engage karne se air ka flow cut ho jata hai . Agreed 💯
Then agar humlog agar choke ko long time tak bhi on rakhe , then due to lack of air (kyuki bacha khucha air toh already used up ho gya hai) then humara vehicle turn off kyu nai ho jata?
As fuel needs air for burning

Sir, if using choke can cut air flow and allows more fuel into combustion chamber, then how come when we run out of petrol in bike still goes to nearby petrol bunk by using choke.?
If fuel is low in tank, how come using choke (using choke allows more petrol into combustion chamber, already petrol is running out in tank) can allow us to ride till nearby petrol bunk.?

[@MECHANICALTECHHINDI]

It allow to enter last drops of petrol to combustion chamber
