Damper definition
The choke is a component of a gasoline engine carburetor that is typically operated at the air inlet of the carburetor through a steering knob mounted on the instrument panel. Its function is to properly close part of the air inlet when the engine is cold start, increase the gasoline concentration of the mixture entering the cylinder, improve the starting performance of the engine, and should completely open the choke after the engine is running normally, otherwise it will be because of the mixture. The engine is not working properly and the fuel consumption is too large. The EFI engine is automatically controlled and does not require manual operation.
