What is the function of injector into the fuel system?
The function of a fuel injector is to spray atomized fuel into the combustion chamber of an internal combustion engine. Fuel injection became the primary fuel delivery system in automobiles starting in the mid-1980s. The spray from a fuel injector can be continuous or intermittent.
How is injection pressure related to fuel pressure?
Injection pressure. The injection pressure here refers to the fuel pressure at the fuel entrance of an injector. In an injector with an internal intensifier the injection pressure refers to the fuel pressure at the exit of the intensifier.
How does a return style fuel injector system work?
Return style systems hold a big advantage in that with a vacuum/boost referenced fuel pressure regulator, the system can maintain a CONSTANT effective fuel pressure, which can extend the range of fuel injectors and help them function at lower fuel demands as well.
How does the nozzle of the fuel injector work?
The nozzle is designed to atomize the fuel, which responsible for making the fuel to easily burn, The amount of time the fuel injector stays open will determine fuel supplied to the engine. This is known as “pulse width” and it is controlled by an ECU device.
Is the fuel injector the same as the carburetor?
Fuel injection system and carburetor using same principle, that is the difference of pressure. However fuel injection system, the pressure on the fuel side is increased so that it is larger than the intake manifold space.
Why is effective pressure important in fuel injector?
When you stick a fuel pressure sensor on the end of a rail, it is reading the pressure inside of the rail. While this number is important, it is only half of the story. Effective pressure is the actual applied pressure for the injector, and is the pressure differential ACROSS the injector.
Return style systems hold a big advantage in that with a vacuum/boost referenced fuel pressure regulator, the system can maintain a CONSTANT effective fuel pressure, which can extend the range of fuel injectors and help them function at lower fuel demands as well.
What sensors control fuel injectors?
The injector control pressure sensor is an engine management component that is commonly found on diesel engines. As its name implies, it is an electronic sensor that monitors the fuel pressure going to the injectors.
What are the functions of diesel fuel injection?
There have been many important developments in pumps, nozzles, and unit injectors for diesel engines over the years, with the latest injection system today relying on electronic controls and sensors. Diesel fuel injection systems must accomplish five particular functions: meter, inject, time, atomize, and create pressure.
