Fuel Injection System Explained Fuel Injection System Explained: Parts, Working, Types & Symptoms: A fuel injection system delivers fuel to the combustion chamber of an internal combustion engine. It ensures the precise amount of fuel is mixed with air for efficient combustion, enhancing engine performance, fuel efficiency, and emission control. Unlike older carburetor systems, fuel injection systems offer better fuel atomization and control. Parts of a Fuel Injection System: 1. Fuel Tank: Stores the fuel. 2. Fuel Pump: Delivers fuel from the tank to the injectors under pressure. 3. Fuel Injectors: Spray the fuel into the combustion chamber in a fine mist. 4. Fuel Filter: Removes impurities from the fuel. 5. Fuel Rail: Distributes fuel to the injectors. 6. ECU (Electronic Control Unit): Controls the timing and amount of fuel injection. 7. Sensors: Include oxygen, throttle position, and manifold pressure sensors to provide real-time data for precise control. Working of a ...
