Fuel injectors are used in both gasoline and diesel engines. They can be either port or direct fuel injectors. Port fuel injectors are mounted on the intake ports of the engine, while direct fuel injectors are mounted inside the engine's cylinders.
Port fuel injectors are the most common type of injector used in gasoline engines. They inject the fuel into the intake manifold, where it mixes with air and is then compressed and ignited by the engine's piston.
Direct fuel injectors are more efficient than port fuel injectors, but they are also more expensive to manufacture. They inject the fuel directly into the engine's cylinders, which reduces the amount of fuel that is wasted and increases the engine's power and fuel efficiency.
Fuel injectors are controlled by the engine's electronic control unit (ECU). The ECU determines how much fuel to inject into the engine based on the engine's operating conditions, such as the engine's speed and load.
