Carburettors Advantages And Disadvantages

A feed pump delivers the fuel through a filter unit to the high pressure piston pumps. The pump compresses the fuel to a pressure of 1000bar. It is then delivered into the high pressure fuel rail; this fuel pressure is independent of engine speed and injected fuel quantity. The ECU controls injectors to inject fuel into the combustion chamber by actuating solenoid valve. The system pressure, the duration of injection and the size and shape of the injection nozzle determine the fuel quantity injected. Pressure in the

A mixture of fuel and air within each cylinder is ignited by a spark from the spark plug. As the fuel combusts, it goes a chemical reaction, yielding gaseous byproducts. Gasoline can only burn if it is in a vapor. The chemical equation for the combustion of the octane within gasoline is: 2 C8H18(g) + 25 O2 Þ 16 CO2(g) + 18H2O(g).” (Science Of NASCAR) The gases the begin to expand, this expansion pushes against the piston, causing it to move downward. Each of the following eight cylinders will then fire, and once all eight cylinders fire, the process repeats itself over again. Indy cars use pure Methanol (CH3OH), while NASCAR’s use the same fuel as your everyday car a “leaded 110-octane gasoline. The lead is in the form of a compound known as tetraethyl lead (Pb(CH2CH3)4).”(Science of Nascar) A small amount of Pb(CH2CH3)4 which is Tetraethyllead this is used to keep the gas from igniting when compressed. Octane, C8H18 (sometimes called noctane or normal octane), is a hydrocarbon that can be compressed fairly well without igniting. Isooctane is an isomer of octane, it’s better at being compressed without igniting, so it’s used in regular gasoline and is given the value of 100 in the octane rating

We need to get some use out of this other wise wasted energy. What we really want is more power, and for this unfortunately the engine needs to burn more fuel. The turbine fed by the exhaust gases connects to a compressor that compresses intake air into the engine, which builds up pressure in the intake manifold. Now when the intake valve opens, the compressed air is forced into the combustion chamber. This allows more air to fill the chamber. We will need more fuel to match the amount of air in the combustion chamber. On computerized cars, computers take care of this accordingly. What you get is a more explosive force from combustion, and more compression, about 60 percent better

The continuing rotation of the crankshaft drives the piston back up, ready for the next cycle. The piston moves in a reciprocating motion, which is converted into circular motion of the crankshaft, which ultimately propels the car. Gas engines usually have about the same about of horsepower as they do torque. The diesel engine usually has twice as much torque as it does horsepower, thus it is the better hill climber and load carrier.

As you drive, air rushes past your car. It hits the front of your car and the intake, and this cold air is forced to the engine. As a combination, the turbo and intake greatly improve power and speed.

For fuel injections the overall set up tends be on the higher priced side, and at times can weigh more than traditional technology. Everything aside this technology makes it less difficult to adjust the fuel to adapt to factors like, track conditions, or perhaps the rider’s preferences. The program works by pumping fuel into an injector, which then sprays the fuel into the body of the throttle. Thus sending a signal to inject a calculated amount of fuel, after receiving information from various sensors. Technology of this type can be extremely beneficial for the average rider, with sensors to monitor things like crank position, throttle position, engine temperature, air temperature, and barometric pressure.

During the late 1900’s, fuel efficiency was given very little thought by automakers. Instead, they competed with each other by coming out with larger and more powerful

Contain 4 main components, Compressor housing, compressor wheel, Turbine housing, along with a turbine wheel. Exhaust gas enters the system through the compressor housing while the air flows over the compressor wheel it causes a chain reaction which results in a counterclockwise rotation of the turbine wheel. This rotation is the stage when exhaust gas turns to air pressure. The air pressure is returned to the engine through a waste-gated return hose/line. The pressurized air is then interchanged with combustible diesel fuel and ignited. The bigger the turbo charger is allows more mass air flow which results in more fuel being burned all this combined equals a greater amount of horsepower

The purpose of this paper is to describe the process of removing an old carburetor and replacing it with a new Holley carburetor on an old Ford 289 engine from a 1965 Mustang. The following terms are required to know for rest of the document to make sense.

The first step you should do is to remove parts that will make it easier to remove the carburetor. These parts could include the seat and any plastic guards around the engine. By removing these parts it gains you better access to the carburetor. Also, it is usually more complicated to work on things you can’t see clearly.

engine uses fuel combustion to pump its cylinders to produce power. The more air that is in the

After gasoline is refined, some chemicals are added. Some of the chemicals that are added are anti-knock compounds. Usually these compounds react quickly to the chemicals in the gasoline that burn quickly so that it could prevent “engine knock”. After this other additives are added to prevent the formation of a gum type of congestion in the engine. The gum is more of a resin that is formed in gasoline that can coat the internal parts of the engine and increase wear.

The piston then travels down pulling in fresh air, (third stroke), after the piston bottoms again it travels up compressing the fresh air, (fourth stroke). The fuel is then injected and one cycle is completed in 720 degrees or two full rotations of the crankshaft.

The invention and use of the internal combustion engine was a pivotal point in the history of the automobile. The first attempt at an internal combustion engine was in 1673 by Christian Huygens, using gunpowder as the fuel source, though it was basically worthless as you had to open the engine up and put new gunpowder in it after every single stroke ("The Fuel & Engine"). This lack of a fuel for internal combustion engines sidelined its development for a couple hundred years. In 1860 Jean Joseph Etienne Lenoir built the first effective internal combustion engine using natural gas (Bottorff). The ignition of the gas would create a vacuum and the resulting pressure difference between the vacuum and the atmosphere would drive the power stroke (Bottorff). This gas-atmospheric engine, as it is known, was an effective system capable generating 20hp, still it was imperfect. It was further improved with the development

We've all seen them before, the mysterious chunks of metal under the hoods of our cars. They start when we turn the key and take us where we want to go. But how does an engine work? Internal combustion engines are a very important part of everyday life. We use them in our cars, trucks, airplanes. boats, snowmachines, 4 wheelers, and heavy machinery. These pages will help familiarize you with the basic concepts of how an engine works, an understanding of engine output, and some information on how forced induction or "boost" increases power output.
