An internal combustion engine may be carbureted as opposed to having fuel injection. Such engines mix fuel and air by passing them through a carburetor, whereas fuel injected engines meter air entering the cylinder and inject the desired amount of fuel directly into the manifold or cylinder itself. These latter engines rely on the injector's atomizing the fuel. Carbureted engines rely on the Bernoulli principle (usually) to atomize the fuel as the air is passed through a venturi, creating a low-pressure area just beyond the fuel intake.
