Automobile

Gasoline must be properly mixed with air before it can be introduced into the cylinder. The combination of gasoline and air creates a more volatile explosion. The fuel pump draws the gasoline from the gas tank mounted toward the rear of the car. The gasoline is drawn into a carburetor on some cars, while it is fuel-injected on others; both devices mix the gasoline with air (approximately 14 parts of air to one part of gasoline) and spray this mixture as a fine mist into the cylinders. Other parts of the fuel system include the air cleaner, which is a filter to ensure that the air mixed into the fuel is free of impurities; and the intake manifold, which distributes the fuel mixture to the cylinders.
