Introduction of petrol injection
The Fuel injection is a system for filling fuel into an internal combustion engine (cylinder). It has become the primary fuel delivery system used in automotive engines, it replaced by carburettors in 1980s. A variety of injection systems have existed since the earliest usage of the internal combustion engine.
There are two type of injection system which used in petrol engine
1st multipoint injection system and
2nd is single point injection system
Herbert Akroyd Stuart developed the first device with a design similar to modern fuel injection
Task 1
Explain the operation of Multi point and single point petrol injection systems used on modern fuel injected engines.
In this task I’ll explain about both type injection systems.
Multipoint injection system In this system petrol engine has injector apart of each cylinder. Means if engine has 3 cylinders then there will be three injectors, one injector on each cylinder. It locates in intake manifold, and when engine piston moves from TDC (top dead centre) to BDC (bottom dead centre) then create sucks and open intake valve by camshaft and entered air and that fuel which injected by injector after taking from fuel tank with help of pressure pump via fuel filter (this component is also necessary in fuel supply system because there is more dust in fuel tank which comes in fuel filling time and it can injure piston ring and block) for blasting with help spark plug. In this system
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

injected to benefit the engine to help with gas mileage and all that and are said to have a ton of
I said earlier that the engine burns fuel and air to cause compression. With a high-burning gas injected into the engine, you gain instant horsepower***. Nitrous Oxide is a gas that burns hotter and faster than regular fuel. When it is directly injected into the cylinder, it burns at a greater rate to the fuel, increasing speed greatly. Through a switch on the wheel, a driver engages a certain amount of NOS**** from a tank in his car. Through a nozzle, the driver decides how much gas he wants then the burst is pressed. With this high-powered gas, too much can literally burn so hot that it melts your engine. These drivers take the risk of wanting too much speed and blowing their engine apart. A NOS boost can shake the welds off the engine and the driver out of the car; this is why it’s a blessing and a curse.
Filling up a car with petrol involves putting a mixture of petrol and ethanol into the fuel tank. The E-number of the fuel indicates the amount of ethanol that has been added. In the UK, most petrol is E5 or E10, 5% or 10% ethanol combined with 95% or 90% petrol. Examples include BP ultimate and Shell V power. In the USA, E15 fuel is commonly used and in Brazil, where sugar cane is grown for fuel, E95 is usual. [1]
Fuel injectors would help lead to the reduction of fuel use, as well as the exhaust causing pollutants to enter the atmosphere. By reducing the amount of fuel, more money could be saved on fuel costs, thus making it advantageous for NASCAR to seek another brand strategy, marketing partnership with suppliers of fuel injectors. This new partnership would help, again, to bring their co-branding strategy into a ‘win-win’ situation with yet another business.
A post collision examination of Vehicle 1 revealed it was powered by a multi-point fuel injected,
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
Maintaining your vehicle can be a lot of work, whether you have a professional do everything or you take on the maintenance duties yourself. You have to keep gas in the tank, get oil changes and even replace and repair parts that stop working.
Fuel System – Getting the fuel from the fuel take to the engine requires a fuel pump that is operational. If not, the gas is going nowhere. We have replacement pumps, lines and more to keep it
A car fueled by a typical gasoline engine runs differently than an electric. Instead of having a battery to power the engine, the car uses an internal combustion unit to propel the car. The gasoline that the owner adds to the vehicle is heated by the combustion unit and is mixed with oxygen to power the engine. When the driver pushes the pedal down, that activates the combustion unit.
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.
A fueling station is a facility which sells fuel and lubricants for motor vehicles. The most common fuels sold today are petrol known as gasoline, gas or diesel fuel.
Conventional cars use internal combustion engines to generate power to put the car into motion. All conventional cars use what is called a “four-stroke combustion cycle” which are “intake
These systems have a fuel injector for each cylinder, usually located so that they spray right at the intake valve. These systems provide more accurate fuel metering and quicker response.
