Fuel SystemsIn this report I will explain the go off systems in an automobile. I will cover different parts and how they work. First thing to do is explain how the burn down system works. The purpose of the fuel system is to hive away 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 both gas or diesel is stored in a fuel tank. A fuel pump draws the fuel from the gas tank by dint of 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 live only one tank but some trucks have two. Fuel tanks can be made of 3 different things. These ar pressed corrosion-resistant steel, aluminum, or molded reinforced polyethylene plastic. The fuel tank has versed baffles or surge plates to restrain 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. either 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 leaded 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 fuel height when the tank is filled. This is achieved by using vent lings at bottom the filler tube or tank. With this design only 90% of the tank is ever full, leaving 10% for expansion. Some vehicles have a over picking limiting valve to prevent overfilling of the tank. Fuel is drawn from the tank by an in-tank or chassis-mounted fuel pump. The fuel pump is the device that draws the fuel from the fuel tank through the fuel lines, to the fuel filter and then to the engines carburetor or injectors. There are two types of fuel pumps mechanical and electrical. The mechanical fuel pump is bolted on the side of the engine block or on the side of the cover of the timing gear.
