EFIsüsteeme

EFIsüsteeme, often referred to as EFI systems, are a type of electronic fuel injection technology used in internal combustion engines. EFI stands for Electronic Fuel Injection. These systems have largely replaced older carburetor-based fuel delivery methods in automobiles and other engines due to their superior efficiency, performance, and emissions control.

The core function of an EFI system is to precisely control the amount of fuel injected into the engine's intake manifold or directly into the combustion chamber. This precise control is achieved through a network of sensors that monitor various engine parameters such as engine speed, throttle position, air intake temperature, and oxygen levels in the exhaust. This data is then processed by an electronic control unit (ECU), also known as the engine control module (ECM).

Based on the sensor data and pre-programmed maps within the ECU, the system determines the optimal fuel-air mixture required for efficient combustion under different operating conditions. Fuel injectors, which are electronically controlled valves, then deliver the precise amount of fuel. This sophisticated management leads to better fuel economy, reduced exhaust emissions, improved engine responsiveness, and smoother engine operation compared to carburetors. Over time, EFI systems have evolved, incorporating more advanced features and becoming integral to modern engine management.
