In this report I will explain the fuel systems in an automobile. I will cover different parts and how they work. First thing to do is explain how the fuel system works. The purpose of the fuel system is to store and supply fuel to the cylinder chamber where it can be mixed with air then vaporized and burned to produce energy. The fuel, which can be either gas or diesel is stored in a fuel tank. A fuel pump draws the fuel from the gas tank through lines and brings it through a fuel filter. Next it goes to either a carburetor or fuel injector and then delivered to the cylinder chamber for combustion.
We will start with the fuel tank. A fuel tank comes in many different sizes depending on how much space is available. Most cars and trucks have only one tank but some trucks have two. Fuel tanks can be made of 3 different things. These are pressed corrosion-resistant steel, aluminum, or molded reinforced polyethylene plastic. The fuel tank has internal baffles or surge plates to prevent the fuel from sloshing back and forth. If you hear splashing in the tank on acceleration or deceleration, this means that the baffles could be broken. All tanks have a fuel filler pipe, a fuel outlet line to the engine and a vent system. All catalytic converter cars are equipped with a filler pipe restrictor so that led fuel, which is dispensed from a thicker nozzle, cannot be introduced into the fuel system. All modern fuel tanks include devices that prevent vapors from leaving the tank. All fuel tank designs provide some control of...
