A carburetor is a device used in automobiles to provide a proper ratio of mixture of air and fuel for easy combustion in the engine. The working principle of a carburetor is based on Bernoulli’s principle. Bernoulli’s principle of fluid flow states that pressure decreases with increasing velocity of the fluid.
