Fuel injection is the introduction of fuel in aninternal combustion engine, most commonlyautomotive engines, by the means of aninjector.
All diesel engines use fuel injection by design.Petrol engines can use gasoline direct injection, where the fuel is directly delivered into the combustion chamber, or indirect injection where the fuel is mixed with air before the intake stroke.
On petrol engines, fuel injection replacedcarburetors from the 1980s onward.[1] The primary difference between carburetors and fuel injection is that fuel injection atomizesthe fuel through a small nozzle under high pressure, while a carburetor relies on suctioncreated by intake air accelerated through aVenturi tube to draw the fuel into the airstream.
Electronic injection
Because mechanical injection systems have limited adjustments to develop the optimal amount of fuel into an engine that needs to operate under a variety of different conditions (such as

Nissan also installed multi-point fuel injection in the Nissan Y44 V8 engine in the Nissan President. Toyota soon followed with the same technology in 1978 on the 4M-E engine installed in the Toyota Crown, the Toyota Supra, and the Toyota Mark II. In the 1980s, the Isuzu Piazza and theMitsubishi Starion added fuel injection as standard equipment, developed separately with both companies history of diesel powered engines. 1981 saw Mazda offer fuel injection in the Mazda Luce with the Mazda FE engine and, in 1983, Subaru offered fuel injection in the Subaru EA81 engine installed in the Subaru Leone. Honda followed in 1984 with their own system, called PGM-FI in theHonda Accord, and the Honda Vigor using theHonda ES3
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.
When the key is in the "on" position the Electronic Control Module (ECM), the main computer that controls all sensors and engine functions, powers up and readies the engine for start-up. When the starter is engaged and the coolant temperature is less than 100 degrees Fahrenheit, determined by the Coolant Temperature Sensor (CTS), the Cold Start Injector provides a spray of fuel to each cylinder via an air distribution system built into the intake manifold. If the engine temperature is greater than 100 degrees Fahrenheit, the Cold Start Injector is disabled by the cold start switch. Upon startup the ECM utilizes information in the Erasable Programmable Read Only Memory (EPROM) to establish the initial pulse rate for the fuel injectors. The ECM pulses, or opens and closes, the remaining 8 fuel injectors in sequence and the engine starts. During this, the Idle Air Control (IAC) valve is com...
The Eco Diesel motor was developed and manufactured by Chrysler supplier VM Motori, a diesel engine
So how about Honda cars? Why does the turbocharger seem to be the definite forced induction of choice for these small inline fours that barely have enough displacement to hold a two litre bottle of soda?
The diesel engines combustion process is a little different than the typical gasoline engine. A couple main things that diesel engines have that gasoline engines do not are, carburetors and spark plugs. Unlike a gasoline engine, air is first allowed into the cylinder rather than a fuel and air mixture. Once the air is compressed it creates a source of heat, then a mist of fuel is injected to start the combustion process which then creates the energy. Since diesel engines do not have spark plugs they are able to take in larger amount of fuel, this obviously means there will be more power and will guarantee better efficiency. Another thing that is very important is that diesel tends to be a better lubricant than gasoline, being that it is a better lubricant there will be less friction which will generally increase the life of the engine (Woodford). Diesel engines operate at slower speeds than gasoline engines, therefore diesel engines tend to have longer lifespans than gasoline
A Modest Proposal for Methanol and Ethanol Powered Cars "We need more stringent regulations on car emissions. Let's add MTBE to the fuel- that will reduce pollution. If people would just stop driving so much, pollution wouldn't be so bad. " People have long recognized the problems with the gasoline we use now. We have tried everything from putting regulations on emissions, to putting additives in the gasoline (only to discover later that MTBE got into the groundwater), to campaigns to get people off the road.
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.
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.
For over 100 years, the automobile industry has relied on gasoline as its main source of fuel. Gasoline is a colorless, highly flammable substance used in internal combustion engines. It is a fossil fuel made from crude oil, a natural gas formed from the remains of ancient plants and animals (Webster‘s Dictionary). Gasoline has positively influenced our way of life by providing convenient, on demand transportation. It has created a global economy that moves people and goods faster and more easily than ever imagined (Povey 12). Although a seemingly perfect substance, it has unprecedented flaws. The tremendous political, environmental, and economic problems resultant from the excessive use of gasoline leads to the conclusion that the automobile industry should not continue to rely on this source of fuel.
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.
Fuel is drawn from the tank by an in-tank or chassis-mounted fuel pump. The fuel pump is the device that draws the fuel from the fuel tank through the fuel lines, to the fuel filter and then to the engine’s carburetor or injectors. There are two types of fuel pumps: mechanical and electrical. The mechanical fuel pump is bolted on the side of the engine block or on the side of the cover of the timing gear.
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
Car pollutants cause immediate and long-term effects on the environment. Car exhausts emit a wide range of gases and solid matter, causing global warming, acid rain, and harming the environment and human health. Engine noise and fuel spills also cause pollution. Cars, trucks and other forms of transportation are the single largest contributor to air pollution in the United States, but car owners can reduce their vehicle's effects on the environment. Car pollution is one of the major causes of global warming. Cars and trucks emit carbon dioxide and other greenhouse gases, which contribute one-fifth of the United States' total global warming pollution. Greenhouse gases trap heat in the atmosphere, which causes worldwide temperatures to rise.
Hybrid cars and trucks are beginning to become very popular in our day of time. The inventor and the founder of the hybrid car was Robert Anderson. Anderson was born in Aberdeen, Scotland. He invented the vehicle in 1839. The hybrid vehicles get better gas mileage than most of the older cars and trucks. Most of the new vehicles that are being made today are some sort of hybrid or ecoboost vehicle. Almost all of your car manufacturers today are trying to create new vehicles that conserve gas which is green to the environment. Gas efficient cars are now taking over diesel car and trucks. Diesel cars and trucks usually get pretty bad gas mileage. Most of the big older trucks have a diesel engine in them. Most of the owners of a diesel vehicle usually don’t drive the vehicle much anymore because of horrible gas and diesel prices this day in time.
The oil refinery converts crude oil into valuable products and supplies. These products are made and sent to many countries abroad, in which are transported on land or along rivers and canals. Crude oil is then arranged and categorized into segments by fractional distillation. Raw crude oil, or unprocessed crude oil, is not normally beneficial in most industrial applications. Low sulfur crude oil has been valuable as a burner fuel to construct steam for the force of seagoing vessels. The lighter elements have the ability to construct explosive and dangerous vapors in the gas tanks. There are extremely hazardous, and are often used in war ships. The remaining hydrocarbon molecules are filtered from crude oil and used towards lubricants, feedstock, plastics, and fuels.
