what does a choke do on an engine

A choke valve is sometimes installed in the carburetor of internal combustion engines. Its purpose is to restrict the flow of air, thereby enriching the fuel-airfuel-airThe stoichiometric mixture for a gasoline engine is the ideal ratio of air to fuel that burns all fuel with no excess air. For gasoline fuel, the stoichiometric air–fuel mixture is about 14.7:1 i.e. for every one gram of fuel, 14.7 grams of air are required.https://en.wikipedia.org › wikiAir–fuel ratio – Wikipedia mixture while starting the engine.

Why do engines need to be choked?

A cold engine won't vaporise the fuel as well as it would in warmer conditions, so the choke helps enrich the mixture (either by adding in more fuel or cutting out airflow) to increase the amount of combustible vapour available to start the engine.27-Aug-2019
