Other vital sensors track engine speed (crankshaft position sensor), coolant temperature, oxygen levels in the exhaust, and throttle plate position, providing a constant stream of data to the central processing unit. The Control Unit, The System's Brain At the heart of the EFI system is the Engine Control Unit (ECU), a robust computer that serves as the system's brain.
EFI System vs Carburetor: How Electronic Fuel Injection Works
The ECU processes this information incredibly quickly, often hundreds of times per second. Different Types of EFI Configurations Not all EFI systems are created equal, and they are often categorized by the location of their fuel injectors.
The system gathers data, processes it, and then enacts precise mechanical actions. The system continuously analyzes a multitude of sensor inputs to make real-time adjustments, ensuring the engine performs flawlessly across a vast range of operating conditions.
EFI System vs Carburetor: How Electronic Fuel Injection Differs
Sensors, The System's Senses Before the system can make a decision, it must first understand what is happening. Another configuration is Throttle Body Injection (TBI), which resembles a traditional carburetor by placing one or two injectors in the throttle body.
