Understand the advantages of electronic fuel injection - what is EFI
The goal of an electronic fuel injection system is to regulate and optimize the fuel/air ratio entering a vehicle's engine. Fuel injection has recently become the primary fuel delivery system used in automotive gasoline engines. Today our ecufixtool article will discuss Electronic Fuel Injection (EFI).
What is EFI Electronic Fuel Injection chip System?
The goal of an electronic fuel injection system is to regulate and optimize the fuel/air ratio entering a vehicle's engine. Fuel injection has recently become the primary fuel delivery system used in automotive gasoline engines.
Electronic fuel injection replaces the carburetor that mixes air and fuel. EFI does exactly what it sounds like. It uses electronic controls to inject fuel directly into the engine's manifold or cylinders.
What are the advantages of EFI?
1. Automatic height adjustment: EFI does this automatically through its electronic controls.
2. Better fuel efficiency: Electronic fuel injection can improve the fuel efficiency of the engine.
4. Reduced emissions: As fuel efficiency increases, they generally produce fewer emissions. Atomization of the fuel also helps the fuel burn more completely.
EFI is also better at avoiding fuel sticking. Because the injection process atomizes the fuel, it burns more completely and doesn't leave residual fuel like carburetors do.
Advantages and disadvantages of electronic fuel injection system:
advantage:
Improve the volumetric efficiency of the engine
Direct fuel injection into the cylinder eliminates manifold wetting
Eliminates icing at the throttle plate
Low volatility fuels can be used since distribution is independent of vaporization
shortcoming:
high maintenance cost
Difficult to maintain
Some sensors may be malfunctioning
How is Electronic Fuel Injection (EFI) controlled?
EFI controllers and sensors
EFI uses sensors to determine how much fuel is needed at any given moment. Every EFI system has some combination of the following parts.
Ecu Electronic Control Unit
ECU is the brain of the operation. It uses engine speed and signals from various sensors to meter fuel. It does this by telling the injectors when to fire and for how long. The ECU typically controls other functions such as the fuel pump and ignition timing.
Throttle Tps Position Sensor
The TPS is mounted on the end of the throttle shaft. It tells the ECU exactly how far the butterfly valve is open. The ECU uses this information to deliver the right amount of fuel.
Replacing or modifying the ECU chip requires certain professional knowledge and technology, and improper operation may cause minor to serious vehicle problems.
Therefore, before modifying the ECU chip, it is recommended to consult or seek the opinions and suggestions of professionals. This is the end of today’s sharing. If you have any questions, you can contact us, or you can follow our official website ecufixtool.
