The fuel injector is nothing but an automatically controlled valve. Fuel injectors are part of a mechanical system that regularly injects fuel into combustion chambers. Fuel injectors can open and close in seconds. In recent years, a carburetor has been used to supply fuel, but fuel injectors have almost completely replaced the carburetor.
- Different fuel injection schemes or types
- Let us briefly discuss some injection systems:
- Throttle body injector
Throttle body injection is the simplest type of injection system. Like the carburetor, the throttle body injector is located at the top of the engine. Throttle body injectors are similar to a carburetor except for their operation. Unlike a carburetor, it has no fuel tank or gauge. In this type of injector, fuel is directed directly to all combustion chambers or throttle openings.
- continuous injection
Continuous injection, as the variant name indicates a constant flow of fuel in the continuous injectors. The ingress of fuel into the cylinder or pipe is controlled by an inlet valve. Continuous injection consists of a constant flow of fuel at a variable speed.
- Central Port Injection (CPI)
The injection system uses a special type of valve called a “valve”. Poppet valves are valves used to control the intake and exhaust fuels and the exhaust fuels in the cylinders. At each inlet, it injects fuel through pipes connected to a central injector.
- Multi-port or multi-point fuel injection
One of the most advanced types of injections used today is called “multipoint or multiport” injections. It is a dynamic type of injection with a separate fuel injector for each cylinder. In a multi-port injection system, all injectors simultaneously inject fuel without delay. One of the most advanced mechanical settings is sequential multi-point injection, which allows each injector to inject fuel just before the cylinder ignites. Thus, by sequentially injecting multiple ports, the driver will have a faster response time.
Today’s fuel injection system is a complex computerized automotive system and is not limited to fuel injectors. The whole process is monitored by a computer, and the various parts interact according to the instructions given. There are many sensors that send important information to a computer for optimization. There are various sensors, such as fuel flow control, to monitor the oxygen level.
Although the system is more complex, the function of the various parts is very subtle. Helps control oxygen levels and fuel flow, as well as avoid unnecessary fuel flow to the engine. Fuel injectors enable your vehicle to operate with a high degree of accuracy.
How to keep your fuel injection system working smoothly
Television commercials speak of fuel injection as if everyone knew what the term meant. But not everyone is a car mechanic, even if they know the term. So the first question is: what is fuel injection? The second question is, why should you take care of its smooth operation?
Apparently, as the name suggests, the fuel injection system delivers fuel to the vehicle’s engine. Although discussed as if it were a completely new invention, it has actually existed since the 1950s. The fuel injection system is designed to meet the need to reduce vehicle pollution and provide fuel for a more efficient continent.
Maintaining a fuel injection system can prevent many problems.
- Replace the fuel filter from time to time
- Fuel injector cleaning
- Fuel flow test
- Spray sample test
Fuel injection has replaced the older carburetor and is paired with a catalytic converter with strict air quality standards. The catalyst converts hazardous emissions into harmless water vapor and carbon dioxide. But to achieve this goal, the fuel must be supplied to the catalyst in the mixture and in the right amount.
It is clear that the fuel injection system plays a key role in the efficient operation of the vehicle. People are no longer qualified and do not have the right diagnostic equipment to test and maintain fuel injection systems. However, it is important that the fuel injection system operates efficiently, taking into account engine mileage and meeting air emission standards.
