This research paper will be about how injectors work and what each part does to work. The injector that is going to be research is 7.3 injectors. There are different styles of injectors but they all operate the same. Some of the injectors work off of push tubes that opens the port on the injector. The injector that is going to be presented is the 7.3 injectors because they work electronically to spray the fuel into the cylinder. The research will be about the injector parts, and what each part does to operate the injector. This will help others who read the research paper know what the injectors do and how they work. Injectors are an important part of diesel engines. If an injector goes out then the cylinder that the injector went out on will be dead. When a cylinder is dead then it is not getting fuel to make the cylinder combust. A diesel engine runs off of combustion as of a gas engine runs off of spark. This is why injectors is a good project because this is what makes the engine run. First off what are some injector parts? Some of the injector parts are the nozzles, injector port plug, and the injector top filter. The nozzle is located on the part of the injector that gets inserted in the cylinder to spray the fuel into the cylinder. The injector has to spray a certain way or all the fuel will not get burned inside the cylinder. The next important part on the injectors is the injector port plug. The port plug is what stops the fuel from running inside the cylinder. If fuel does run into the cylinder that cylinder will flood out and cause that cylinder to be dead. The only way the port plug should open is when the fuel pressure exceeds the certain pressure to open the port plug to let the fuel go to the injector nozzle. The... ... middle of paper ... ...leage. How to prevent injectors from going bad is to have them cleaned. They can be cleaned in many different ways. The best way to clean them is buy a diesel fuel supplement to dump in with your fuel and it will clean the injectors that way. Another way to clean the injectors is to manually take them out of the engine and clean them by hand. The best way is to dump the fuel supplement in with the fuel. The process of replacing fuel injectors on a 7.3 is to remove the valve cover off of the engine. After that unplug the wiring off of the the injector and the glow plugs which is also connected to the valve cover gasket. Then you take the bracket holding the injector in place and loosen the top bolt on it and take the bottom one completely off of the bracket. When you have done that then you can take a pry bar and pry the injector out of the hole it is located in.
