fuel injector
A fuel injector is a device used in internal combustion engines to deliver fuel into the combustion chamber in a controlled manner. Fuel injectors replaced carburetors in modern engines due to their higher efficiency and lower emissions.
Fuel injectors are typically located in the intake manifold or in the cylinder head, and they are controlled by the engine's electronic control unit (ECU). The ECU monitors various engine parameters such as engine speed, load, and temperature, and uses this information to determine the amount of fuel to be injected into each cylinder. The fuel injector consists of a solenoid-controlled valve that opens and closes to allow fuel to enter the combustion chamber. The fuel is delivered at high pressure through a small nozzle, which atomizes the fuel into a fine mist for more efficient combustion. Fuel injectors are designed to operate at high pressures, typically between 30 and 100 psi.
The proper operation of the fuel injector is essential for the proper operation of the engine. Malfunctioning fuel injectors can cause a wide range of problems, including rough idling, decreased performance, and increased emissions. Fuel injectors can become clogged or develop leaks over time, and may need to be cleaned or replaced to maintain proper engine performance.
