Most road cars run off of gasoline, or pump gas. It is a very effective mixture that does its job well when it comes to internal combustion engines, but it’s not the most potent fuel mixture you can find. You may have heard of a type of racing called “Top Fuel”, it is the fastest type of racing in the world. Where your car may push out around 200 horsepower, the Top Fuel cars can have up to 10,000 horsepower, they can get to over 300 mph in less than 4 seconds. This insane speed is due to their massive engines, and very potent fuel, nitromethane. A 4 stroke engine has four steps to complete one cycle. First, there is the intake stroke; this is where the fuel mixture is pulled down into the engine. Second, there is the compression stroke; …show more content…
The gasoline (C8H18) and oxygen have to be at an almost perfect ratio. Usually for every 1 pound of fuel, it has to have close 15 pounds of air to burn properly. If this ratio is off, the car will struggle to run, or not run at all. This is why nitromethane can make so much power. When burning nitromethane, for every pound of nitromethane is burned, it only needs 1.7 pounds of air to burn. Technically speaking gasoline is more powerful, but since you can put a lot more nitromethane through the engine, you can make more power. Top Fuel dragsters can actually burn up to 1.5 gallons of fuel, every …show more content…
When normal gasoline is burned inside an engine, it burns completely, and then exits the engine through the exhaust. When nitromethane is ignited, it burns too slowly for it to burn fully. So when the exhaust valve opens in these engines, the fuel is still burning. This is why you see flames shooting out of the exhaust pipes on these dragsters. Another characteristic comes down to the pressure at which fuel is ignited. On most sports cars, they have a compression ratio of about 10:1. This means that when the fuel mixture is compressed fully, it is a tenth of the volume it was when it entered the engine. If the compression was any higher, the fuel would ignited just by pressure alone. Nitromethane can take insane pressure without being ignited prematurely, even so most dragsters only have a compression ratio of about 7:1, but they have four ignition sources where your car has
3.Combustion: As the piston reaches the top of its stroke or TDC, the spark plug fires, igniting the mixture. Due to the high compression of this mixture it is very volatile and it explodes when the spark is introduced. This pushes the piston downward and produces power.
Each nitro dragster is equipped with a custom supercharged and fuel injected engine, which is the real power of the beast. Another very crucial part of the car is its parachute launch system, which if he drivers didn't have would be a very rough and maybe lethal stop. Also one of the most powerful parts of the machine is the gas which is a nitromethane. The dragsters can use up to fifteen gallons of nitromethane in only one run. Another fascinating fact is that the dragsters are twenty five feet long and two thousand three hundred and thirty pounds. The top fuel dragsters pull eight gs on launch, and also have have amazing drivers who react to the start light in less than a tenth of a second.. The “fire breathing monsters of the NHRA” as they are called are a man mad true feat of engineering. When you look back at how the NHRA started you would be shocked and amazed by the mechanics and systems that go into each nitro drag
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.
Nitrous, is something totally different from turbo. Nitrous is a gaseous mixture that is either directly injected into your engine's pistons or into you intake manifold. Nitrous is cheap and gives you a lot of power. It costs about 500 dollars and depending on how much you want to spray is how much horsepower your engine will receive. A 50 shot of nitrous gives you about 45 more horsepower. What is impressive about nitrous, is that you only use it when you want because all you have to do is flip a switch and then it works. The down side of nitrous is that it burns your engine, and if used frequently it will damage your engine beyond repair.
The rest of the hot gases are forced through the necked-down exhaust nozzle, thus accelerating them further. The force of the hot gases expelled in the exhaust, provides all of the planes thrust.
The ecologists are of the opinion that the racing industry is an unnecessary burden for the society, that it does not serve any purpose. But the fact is that the racing industry is just like any other industry that is driven by diesel fuels like car manufacturing and airplane development. If these two consumer goods are considered an important part of human technological innovation, there is no need to sideline the racing industry. On the basis of this, we can also say that using biofuels for racing is preposterous because the biofuels cannot give the thrust that the racing cars need in order to compete. Biofuels are not of high-octane in nature; diesel fuels are. Biofuel cannot be characterized as an energy rich fuel. Using biofuel instead of diesel fuel will negatively impact the performance of racing cars, leading to heavy losses for the racing industry (The Royal Society 08).
Why do I Dragster? A question that at first may sound really weird. This question actually asks why would you want to race C02 cars. First, to understand what this is, lets start with the Basics.

Tires are the most important part of race or any car for that mater. (Physics of Racing) After all they are the only thing that is contact with the ground! Tires work by having a high coefficient of friction. Some slicks have a friction coefficient grater then 1! (Physics of Racing) Typical normal street tires have coefficient of about .5 to .6 . In physics we learned that friction was equal to mew times the normal force. Since race cars are typical much lighter then normal cars, they use tricks to increase the downward force on the tires. Some drag tires run really low pressure, other drag cars tune the car to lift the front wheels to put all the weight on the rear tires. Indy cars use a wing to generate down force, and ventures to suck the car to the ground. (How to Make Your Car Handle)
Starting from the point where the spark plug fires. Previous to this, the piston has compressed the fuel/air mixture in the cylinder. When the spark plug fires, it creates an explosion. This explosion drives the piston downward which turns the crankshaft, which is attached to the shaft that drives the cutting deck on the lawn mower. As this is happening it is compressing the fuel/air mixture that has come from the carburetor, in the crank case. As the piston starts to go down, the exhaust port is uncovered, and the pressure in the cylinder forces most of the exhaust gases out of the chamber.
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.
Honda, The Car Everyone Needs Beep! Beep! Beep! Goes the alarm clock in the other room. Oh man, surely it can't be time to get up yet, you think to yourself. As you scramble out of the bed and into the shower, the thought crosses your mind, I hope my car starts.

In order to have a fast and efficient car all these things I have discussed need to be taken into consideration. A fast car should be designed with aerodynamic surfaces for a balance of maximum production of downforce and minimum drag creating surfaces. It should have as small an engine as possible to reduce mass and reduce the necessary size of the frontal area, but a large enough engine to be able to produce enough horsepower to be able to create more force than the resistance the car faces to accelerate and enough to balance with those forces at high speeds. The tires should be wide enough for fast acceleration and good cornering but not so wide it creates large amounts of rolling resistance. Your overall best example of such a car would be formula one races or Indy cars because they have to have good handling, fast acceleration and reach and maintain high speeds.
The global company Mercedes-Benz is considered one of the most successful and well-known automotive companies worldwide. Since 1886, the company’s founders Gottlieb Daimler and Carl Benz made history with the invention of the automobile, including the Daimler Group, which is one the biggest producers of premium cars and the world’s biggest manufacturer of commercial vehicles globally (Daimler, 2013). Their main focus is innovation, safety, technology, style, brand image, expansion, and superior automobiles by offering the best of the best to consumers worldwide. The brand’s philosophy is to continuously create radically new products to advance the cause of human mobility. It is also the number one luxury brand in the United States and Germany while continuously expanding in China and Russia as well (Interbrand, 2013). Mercedes-Benz has a great selection on divisions such as cars, trucks, vans, buses, and financial services offered to any consumer or business.
