What is Fuel Injection Technology?

Working Principle:

Taking the electronic control gasoline injection system as an example, the electric fuel pump is installed inside the fuel tank. It draws fuel from the tank and pressurizes it. The pressurized fuel then passes through a fuel filter to remove impurities before being delivered to the distributor pipe located above the engine. The distributor pipe connects to injectors mounted on the intake manifold of each cylinder.

The injector is essentially an electromagnetic valve controlled by the computer (Electronic Control Unit, ECU). Based on signals from sensors such as the air flow sensor and crankshaft position sensor, the ECU calculates the engine's air intake volume and speed, determining the basic fuel injection quantity accordingly. It further adjusts the fuel injection quantity based on operating parameters like throttle opening, engine coolant temperature, and intake air temperature. The ECU controls the duration of each fuel injection cycle to regulate the amount of fuel injected, ensuring that the fuel is sprayed in a fine mist into the intake manifold where it mixes with air and is drawn into the cylinders during the intake stroke.

Advantages:

Improved Fuel Economy:

• Precise Fuel Injection Control: By accurately controlling the fuel injection quantity, it ensures complete combustion of fuel, reducing waste and lowering fuel consumption.

Enhanced Power Performance:

• Optimized Fuel Injection for Various Conditions: The system can promptly adjust the fuel injection quantity and timing according to different engine conditions (e.g., idle, acceleration, high-speed driving), optimizing the air-fuel mixture concentration. This improves the engine's output power and torque, enhancing acceleration performance.

Reduced Exhaust Emissions:

• Complete Combustion: Precise fuel injection control promotes more thorough combustion, reducing emissions of harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides, thus meeting increasingly stringent environmental standards.
