FUEL INJECTION SYSTEM

FUEL INJECTION SYSTEM

Fuel injection is the injection of fuel in an internal combustion engine, most commonly automotive engines. A fuel injection system can be termed as the introduction of the right amount of energy into a machine at the correct time to function correctly and produce the desired power fuel injection system works by atomizing the fuel at high pressure, mixing it with clean air as it passes the inlet manifold, before entering the combustion chamber of each cylinder. The key element of this process is the injector. To check the one for your type engine, click https://oilsfluids.com/which-fuel-injection-system-is-right-for-you/ 

WHFUELUL INJECTION SYSTEM IS NECESSARY

• Improve Your Engine’s Performance because e engine relies on fuel and the fuel injection system that delivers that fuel.
• Fuel injection system-equipped engines provide higher power and torque than the same version carbureted engine.
• It delivers less Fuel Consumption and lower Emissions.
• Fuel injection system increase ReliabilityThe fuel injection system offers less Maintenance and Downtime because this service cleans all connections like the fuel rail, the pressure regulator, and the vacuum lines fuel injection system provides appropriate needed power to the o engine and also eliminates the cold start problems.
• This system Improves starting of the engine because it removes rust, corrosion, and debris. 

WHFUELUL INJECTION IS BETTER THAN CARBEURATOR

     The fuel injection system is superior because;

• Increases engine’s strength

                   In a fuel injection system, the fuel injector introduces fuel into the intake manifold at a very precise angle. The air-fuel mixture is compressed in the combustion chamber, igniting the chemical reaction required to power your engine precisely. All compression-ignition engines (e.g. diesel engines), and many spark-ignition engines (i.e. petrol engines, such as Otto or Winkle), a useful injection systems.

• controlled process 

 The fuel injection system uses modern electronic controls that are more accurate, fuel delivery can be tuned to match driver demand. Carburetors are not that accurate to account for changes in air or fuel temperature or atmospheric pressure.

• Reduce fuel consumption and emission

                   Fuel injection results in more efficient use of fuel reduced fuel consumption and causes the lowest achievable exhaust emissions.

How the fuel injection system works:

During the fuel injection system process, a high-pressure electric fuel pump pumps fuel at a pressure of 100psi up to a fuel accumulator. It is a short-term reservoir that keeps the pressure of fuel constant. From the accumulator, the fuel moves through a filter and then moves into the fuel-metering control unit, also known as the fuel distributor. This unit functions to distribute the fuel to each cylinder, at the correct time and in the correct amounts. The amount of fuel is controlled by a valve that is located in the engine’s air intake. These valve sites are beneath the control unit. When the throttle is opened, the valve rises and falls and sucks fuel from the cylinder to increase airflow. This movement of the valve control unit allows more fuel to be sprinkled into the cylinders. From the metering unit, the fuel is delivered to each of the injectors and then fuel is sprayed into the inlet port in the cylinder head. Each injector contains a valve that remains closed and open only when fuel is sprayed. The airflow can only be controlled through a manual control on the dash that resembles a choke knob to control the air-flow mixture.

DIFFERENT TYPES OF FUEL INJECTION

          Many fuel injection systems are available, each with unique advantages and disadvantages. These are the four most popular types

• Single-Point Fuel Injection System (SPIFS) or Throttle-body injection

          SPIS is a type of fuel injection system that uses one injector only. One injector introduces fuel to 4 cylinders of the engine. This fuel injection system is also known as a throttle-body injection because an injector is placed on the throttle body as a substitute for playing a jet carburetor. SPIS is more accurate than a carburetor system. It is useful. After all, it reduces fuel economy but t engine’s performance at high RPM is slightly disturbed because it uses only one injector.

• Multi-point fuel injection system (MPFIS) or Port injection

          Multi-point fuel injection (MPFI) is an advance technology than the single-point type. This fuel injection system works the same as SPIFS but uses 4 injectors for 4 cylinders the of engine for the supply of fuel and when the fuel is sprayed, the fuel can go directly into the cylinders. This process is not helpful to reduce fuel economy but is better than single point type in improving the engine’s performance.

• Sequential fuel injection (SFI)

           SFI system is the mostly used fuel injection system in recent vehicles. It works the same as MPFIS but in this system, all 4 injectors don’t work at the same time. Each injector works alternately according to the timings of each cylinder. SFI has a more complex controller scheme because it uses timing indicators for each cylinder but is better for the performance of the engine and use of fuel.

• Direct injection system (DIS)

          This is a fuel injection system mechanism that places the injector directly into the cylinder. This is the latest type of fuel injection system, where the injector will spray fuel directly into the cylinder. In performance regard, it is equal to or sometimes better than MPFIS depending upon the volume of fuel that comes out. The main advantage of this fuel injection system is fuel economy.

Conclusion (Which fuel injection system is right for you)

There is no single fuel injection system that is superior to all others. It all depends on your driving habits and engine type. You must choose the fuel injection system that will best suit your needs. Your fuel system will depend on your driving style and engine type because fuel flows through the injector in the fuel injection system at a variable flow rate.
