What is choke in an internal combustion engine?

In internal combustion engines with carburetors, a choke valve or choke modifies the air pressure in the intake manifold, thereby altering the air–fuel ratio entering the engine. Choke valves are generally used in naturally aspirated engines to supply a richer fuel mixture when starting the engine.

What does a choke do for an engine?

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.

Should the choke be open or closed?

The choke is only used when starting a cold engine. When doing a cold start, the choke should be closed to limit the amount of air going in. Once the car has warmed up, if the choke does not open fully, the restriction in air may result in reduced power.

Where is the choke located?

The choke is located before the throttle, and manages the total amount of air going into the engine. The choke is only used when starting a cold engine. When doing a cold start, the choke should be closed to limit the amount of air going in.

What happens when choke is pulled?

By pulling the choke you increase the amount of fuel to the engine.. So.. while starting the vehicle on a cold day, the engine needs more amount of fuel to heat up the engine for normal performance of the vehicle... It is not recommended to put the choke on and drive the bike..

What happens when the choke is on?

Food goes down the esophagus and air goes down the trachea or windpipe. ... But, when the object is lodged further down the trachea it blocks airflow to the lungs. If someone is truly choking, they won't be able to breathe or talk and their face might turn red.

How long do you leave the choke on?

After 30 seconds is usually enough for most bikes. Especially a small thumper. Just reduce the choke slowly. If it wont idle smoothly (sounds like an asthmatic pensioner) then it probably wants the choke on a bit longer.

What does choke on mean?

choke on something

to gag and cough on something stuck in the throat. The dog choked on the meat. The restaurant patron began to choke on a fish bone. See also: choke, on.

What does open choke mean?

The purpose of a choke is to keep the shot together over a pre-determined distance before it starts to spread. An open choke ( think no choke) allows the shot to start spreading as soon as it leaves the muzzle and the wad (which holds the shot together) falls away from the shot.

What is the run position on a choke?

Choke is all the way to right and run is all the way left.

Can I ride with the choke on?

No, it is definitely NOT o.k to ride with the choke on,the choke restricts the air supply to the engine when starting, to make the mixture petrol rich,as soon as the engine is warm enough to run without it should be closed.

Can you drive with the choke on?

It will not damage the engine at all. All that will happen is that it will run richer, thus using more fuel. If you did it for thousands of miles you'd probably end up with more deposits in the engine/exhaust, but even that is easy to sort.

Can you only run with choke on?

If a motorcycle or ATV only runs with the choke on, it's because the richer “choke on” mixture is actually closer to the engine's normal operating fuel mixture than the leaner “choke off” mixture. So when the choke is turned off, the engine gets too little fuel and too much air for it to run and it stalls.

What causes choking?

Choking occurs when a piece of food, an object, or a liquid blocks the throat. Children often choke as a result of placing foreign objects into their mouths. Adults can choke from breathing in fumes or eating or drinking too rapidly. Most people choke at some point in their lives.

Can leaving choke on damage engine?

Leaving the choke on for too long will cause unnecessary engine wear and waste fuel. ... The engine needs its fuel to be vaporised in order to burn it. This is done by the carburettor where the fuel is mixed with clean air coming from the air filter, and sent into the pistons to be ignited.
