Fuel Injector

A fuel injector is a device used in internal combustion engines to deliver fuel into the combustion chamber or intake manifold. It is an electronically controlled valve that atomizes the fuel and sprays it into the engine in a precise and controlled manner.The main function of a fuel injector is to deliver the right amount of fuel at the correct time to ensure efficient combustion. It plays a crucial role in the overall performance, fuel efficiency, and emissions of the engine.Modern fuel injectors are typically found in gasoline and diesel engines. They are usually mounted on the intake manifold or directly in the combustion chamber and are connected to the fuel supply system. The fuel injectors receive signals from the engine control unit (ECU) which determines the amount of fuel to be injected based on factors such as engine speed, load, and operating conditions.When the fuel injector receives the signal, it opens an internal valve, allowing pressurized fuel to be sprayed through a small nozzle or multiple nozzles. The fuel is sprayed in a fine mist or a cone-shaped pattern, which improves atomization and facilitates better mixing with the incoming air.The precise control over the fuel delivery provided by fuel injectors allows for better combustion, improved power output, reduced emissions, and enhanced fuel efficiency compared to older carburetor systems.It's worth noting that there are different types of fuel injectors, including port fuel injectors, which inject fuel into the intake port, and direct fuel injectors, which inject fuel directly into the combustion chamber. The exact design and operation of fuel injectors can vary depending on the engine type, fuel system, and technology used.
