Background Infromation
In Cambridge England, in 1820 a man by the name of Reverend W. Cecil was explaining to fellow scientists and inventors how an internal combustion engine worked. All of his fellow colleagues just laughed at him and told him it could never be done.
In 1860 Jean Joseph E'tienne Lenoir made Cecil's idea come to life by building the first practical internal combustion engine. Three years later in 1863 Lenoir built one of the worlds first gas engine cars.
Ignition System
Have you ever wondered how turning a simple key will start a car? Well, I'll tell you. When you turn the key a small voltage from the cars battery is sent to the coil. The coil turns the small voltage into a large voltage. Then the coil sends the the voltage to the distributor.
The distributor has heavy wires that send the voltage to each spark plug. The distributor, also, tells the spark plugs which one should fire and when to fire.
The altenator is another part of the ignition system. The basic job of the altenator is to make more voltage to charge the battery.
Fuel System
Everyone knows that you need to have gas in your car for it to run. When you put gas into the car it goes into the gas tank. The gas then makes its way from the tank to the carberator via the fuel pump.
The carberator mixes the gas and air together. The air is first cleaned by the air filter before going to the carberator.
The air and gas mixture is then sent to the intake manifold, from there its sent to the intake valve.
Combustion
The camshaft opens and closes both the intake valve and the exhust valve. When the intake valve opens, the air and gas mixture rush into the cylinder. The valve closes and the mixture is traped inside.
The piston is pushed up and causes compression. At just the right moment the spark plug sparks and ignites the mixture. When the gas explodes it pushes the piston back down.
When the piston is at the bottom of the stroke, the exhuast valve opens sending the exhaust out through the tail pipe.
Exhaust System
Once the burnt fuel is throught the exhaust valve it is sent to the exhaust manifold. The exhaust maniflod is just a collecting area for the exhaust coming from the cylinders.
Pressure keeps the exhaust moving to the pipes then into the muffler.
This paper has informed you on multiple parts and operations of 7.3 litre injectors. Listing their parts, both internal and external. How the entire system works as one, and how it makes the engine run. Without fuel of some sort the engine would not run. So with this research paper I hope you have learned something.
The paragraph above relates to model rockets because our rockets motor is made up of a special fuel. The fuels two reactants are Potassium Nitrate and sugar or sucrose. When these two reactants are mixed together and ignited they create a violent combustion. When my rocket is launched it will have it’s fuel ignited. The two reactants will combust and produce an exhaust that pushes the rocket forward.
Gasoline engines have four strokes and six processes in each cycle. During the intake stroke, air and fuel are drawn into the cylinder; the volume and potential energy increase. Next, the compression stroke adiabatically compresses the gases; the volume decreases and the temperature increases. The spark does not occur during a stroke but when the piston is fully raised, this causes the gases to ignite keeping relatively the same volume. In the power stroke, the gas adiabatically expands; the temperature decreases and the volume increases. Finally, the exhaust valve is opened so in the exhaust stroke when the piston moves up the gasses are released causing the volume to decrease.
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...
For over a century people have relied on automobiles, planes and trains as means of transportation, industry and agriculture, it has become such a successful necessity in the modern world that it has become a need for people to use them to get by. Now sure the three basic means of transportation are entirely different in the way the function and their use. All of these means of transportation would not be possible without this invention transportation could not be possible, The Internal Combustion Engine. You might be wondering what is exactly is an Internal Combustion Engine? It’s actually a simple concept but the way it’s performed can becoming very complex. The function of is to create a pulling force through a controlled explosion of compressed air and fuel inside a combustion chamber which then pulls a crank. Depending on what type of platform the engine is on will determine what the crank turns, for an example in a car the crank then turns either a front or rear axle which that axle transversely turns a wheel. In order for this engine to function in needs three elements - air, fuel and spark and without one of these elements the engine will not function, so it takes precise timing and careful planning by the Engineers to make the engine work as required.
1.Intake: The intake valve opens allowing fresh oxygen rich air mixed with fuel to enter the cylinder.
The Diesel engine, a compression ignition, internal combustion engine, was invented in 1893 by French inventor Rudolf Diesel. Diesel continued to developed his invention until 1897. “[his]... compression ignition engine could burn any fuel, the prototypes he built would run on peanut or vegetable oil–and needed no ignition system: It ignited by introducing fuel into a cylinder full of air that had been compressed to an extremely high pressure and was, therefore, extremely hot.” The Diesel engine impacted greatly on society in many ways, both good and bad.

...o turn it back into a high pressure gas. The gas is then used to turn a turbine and a generator to produce electricity (Liquid Air Energy Netwrok, 2012).
In the future the automotive industries will need alternative fuel sources, in turn that means they will need alternative engines in their automobiles. The engines found in their cars will have to be changed to fit the new fuels being made. They have many directions in which they can go concerning engine types and fuel types.
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.
Firstly, the gas turbine engine operation begins with the air intake process. As of all internal combustion engine, oxygen is required to support the combustion of the fuel and the source of oxygen is from the fresh air that is taken in. Initially, the fan is rotated by a driving shaft that is powered by the turbine of the engine. A negative or vacuum pressure at the intake side is then created by the rotating fan. Next, the surrounding air is drawn towards the inlet and causes it to flow into the gas turbine engine inlet (Cengel & Boles, 2011). At the same time, the pressure on the other side of the fan is increased as it is compressed at a lower pressure ratio and causes the air in the outlet side of the fan to move fu...
As the piston rises, the pressure forces the poppet valve closed, and the mixture is compressed. Once the piston reaches its peak, the spark plug fires, igniting the compressed fuel causing the fuel to expand driving the piston downward. The exhaust valve opens after the piston reaches its lowest point. As the piston begins to rise, the exhaust fuel is driven out of the chamber. Large four-stroke engines tend to have more than one cylinder and often feature valves, fuel injectors, and turbochargers (Four Stroke
Finally, the liquid moves to the evaporator, where heat from the inside air is absorbed and changes it from a liquid to a gas. After that, it goes again to the compressor, where the entire cycle is repeated.
An ignition circuit consists of two sub-circuits: the primary, which carries low voltage; and the secondary, which carries high voltage. The primary circuit, controlled by the ignition key, releases 12 volts of electricity from the battery or alternator through the coil to a set of breaker points ...
