Brand: Nissan

Model: non

Regularly and quantitatively injecting fuel, atomizing fuel to improve combustion efficiency
The fuel injector is a key component in the fuel supply system of a car engine, and its core function can be summarized as follows:

1、 Core functions

Timed and Quantitative Fuel Injection: Based on the instructions of the engine ECU, the injection time and quantity are precisely controlled to ensure the optimal fuel to air mixture ratio (air-fuel ratio), thereby coordinating the ignition time of the valve mechanism.
 

Atomized fuel: By using the principle of an electromagnetic valve (the needle valve lifts when powered on, and the fuel is sprayed at high speed from the annular gap to form a mist), the mixing effect of fuel and air is greatly improved, promoting full combustion.
 

Impact on power and emissions: The higher the degree of atomization, the higher the combustion efficiency, which is directly related to engine power output, fuel consumption, and exhaust emissions cleanliness.

2、 Differences in spraying methods

Intake manifold injection: The fuel injector injects fuel into the intake manifold, mixes it, and then enters the cylinder. The advantage is to clean the valves and reduce carbon deposits, but the fuel injection accuracy is low, which may increase fuel consumption.
 

Direct injection in cylinder: Fuel is directly injected into the combustion chamber with higher precision, which can improve fuel utilization and enhance power, but strict requirements are placed on fuel quality and injection pressure.

3、 Other related effects

Blockage or carbon buildup in fuel injectors can cause a decrease in power and an increase in fuel consumption, requiring regular cleaning (generally recommended for 2 years or 50000 kilometers, adjustable depending on fuel quality and road conditions).
 

Modern fuel injectors are mostly electromagnetic valve structures, replacing traditional carburetors and becoming part of electronic control systems.
 

Summary: Fuel injectors directly affect engine performance, environmental friendliness, and fuel economy through precise fuel injection and atomization, and are the core executing components of electronic fuel injection systems.
