What are the components of electronic fuel injection system EFI and give their functions?
Electronic fuel injection (EFI) is a technology that monitors and controls engine functions using electrical and electronic devices. Electrical signals in the form of current or voltage received by an electronic control unit (ECU) or a computer from numerous sensors.
What is the three basic EFI systems?
Systems Approach EFI can be separated into three basic control configurations: alpha-N, speed density, and mass airflow systems. Alpha-N is the simplest, with the most complex name.Apr 3, 2008
What is the function of EFI system?
Your electronic fuel injection (EFI) system is designed to rapidly deliver fuel to the engine in a highly efficient manner, helping your vehicle to run smoothly, at peak performance and using the minimum amount of fuel.
What is needed for EFI?
EFI systems require much higher fuel pressure than carburetors do, so you'll need a high-pressure fuel pump to support that. Those can be installed in-tank or externally mounted, depending on the application's requirements.Jun 4, 2021
What is the advantage of EFI engine?
EFI-equipped engines provide higher power and torque than a carbureted version of the same engine. They optimize air/fuel ratios and ignition timing while compensating for other factors to maintain continuous optimum performance.Dec 1, 2017
Is EFI engine good?
Since EFI engines deliver air and fuel with better accuracy than a carburetor engine, they generally produce fewer emissions to go along with the improvement in fuel efficiency. Atomization of fuel also helps burn the fuel more completely.
Which is better carburetor or EFI?
Warren Johnson: Properly tuned, carburetors make more peak power than EFI in a Pro Stock engine. ... EFI performs well over 2,000 rpm or more. On average, if optimized, both systems perform about the same as far as how fast you get down the track. However, the EFI system is much easier to tune than a carburetor.Jan 1, 1999
How does an EFI engine work?
An EFI system consists of a fuel pump, fuel injectors, sensors and an Engine Control Unit (ECU). Fuel gets pumped up from the tank via a fuel pump out to a fuel injection rail, then into individual injectors which are inserted directly into the intake manifold. The fuel injectors are controlled by the ECU.

Can you tune a fuel injected car?
Most EFI Kits are designed to be plug-and–play. Just enter some basic information about your engine into the handheld controller and you're up and running. From there, the system will tune itself as you drive. ... If you want ultimate control over your system, you can have that too.Jul 24, 2020
