The fuel injector is a device that pumps fuel directly into the engine. It supplies and maintains the precise amount of fuel required by the engine at any given time.
Not all engines use injectors, however. Many modern cars have cylindrical fuel elements that run from one end to the other inside the fuel tank. This is referred to as a Wankel engine or an internal combustion engine (ICE).
Extracting fuel from the tank is done via a small cylinder called a pump or an electrical pump that transfers the flowing gas into the system. To clean these injectors, you can search for the Best Fuel Injector Cleaner UK.
What is a fuel injector?
The fuel injector was invented by Edward F. Constant of Detroit, Michigan in 1905 while he was employed by the Packard Motor Car Company. The fuel injector is a device that pumps fuel into the car’s combustion chamber, where it mixes with air that has been drawn in by the intake manifold. It is an electromechanically-actuated pump used for delivering fuel into the combustion chamber of a four-stroke cycle internal combustion engine.
Why Fuel injectors
All petrol engines rely on the intake and combustion of air mixed with vaporized fuel from a carburettor or fuel injector; all diesel engines rely on compression and combustion of air mixed with vaporized fuel from the direct injection (DI) — and no carburettor.
The fuel injector is a device that meters the flow of fuel to an internal combustion engine in a finely atomized spray. Fuel injection replaced earlier carburettor systems, which are less efficient, more polluting, harder to start and maintain, and less reliable.
The main reason for replacing carburettors with fuel injection is to eliminate carburettor ice. This occurs when water droplets suspend in the air box by the venture effect and turn to ice while ventilated by the airflow.
Diesel Fuel Injectors
The importance of a Diesel Fuel Injector is paramount to a diesel engine. It ensures the right amount of fuel is injected into the cylinder so that all the air and fuel are mixed adequately. The injected fuel ignites in the combustion chamber, producing energy to rotate the crankshaft and drive the pistons up and down.
A diesel fuel injector, also known as a fuel injection pump, is an automated mechanical device that regulates the amount of diesel fuel delivered to the engine.
These types of injectors range from a single nozzle to multiple nozzles, and these injection points can be centrally located or they can be at the peripheral edges of the engine.
Mechanically Controlled Fuel Injector
Mechanically controlled fuel injectors are found on nearly all gasoline-fueled, internal combustion engines. Carmakers spend a great deal of time and money developing high-performance vehicles that perform at their peak efficiency levels when driven correctly. While there are countless technologies and design features built into the engine, many of these performance features are dependent upon the fuel injectors. That’s why it’s essential to understand how these mechanical devices work.
Since the invention of the diesel engine at the turn of the 20th century, the emphasis on reducing diesel combustion noise and hydrocarbon and particulate emissions has led to increasing efforts to control these parameters by injecting fuel in a precisely metered manner.
But even with modern fuel injection systems, limitations inherent in important operating parameters such as injection timing, injection rate, and fuel temperature continue to greatly influence the efficiency of combustion and levels of engine emissions.
Bottom Line
Fuel injectors are responsible for spraying fuel into the combustion chamber of an internal combustion engine in a fine mist. This allows for a greater amount of fuel to be used by the engine than traditional carburettors. Besides, fuel injectors give more precise control over the fuel mixture entering the combustion chamber than carburettors.
