How does the fuel rail injector system work?
How fuel rail works 1 It supplies the injectors with fuel. 2 The high-pressure pump applies system pressure to the fuel, which the fuel rail then delivers to the injectors. 3 A high-pressure pump adjusts the pressure in the fuel rail whenever necessary.
Where is the fuel rail on a car?
The fuel rail is the long, round metal bar that runs along the top of the injectors and is held onto the manifold with a few bolts. It supplies fuel to the fuel injectors mounted directly on the fuel rail.
What happens if you put too much gasoline in the injector?
Either way, you need to find the cause of the gasoline odor and fix it right away before it becomes a big safety hazard. If the fuel injector is spraying too much fuel into the engine cylinder, this will create a surge in the engine causing your acceleration to be much slower.
Where is the fuel injector located on a diesel car?
Fuel Injector Location The fuel injectors are located on the engine’s intake side, under the fuel rail, which is often located on the intake manifold. If you have a diesel car, your fuel injector is likely located in the cylinder head, but gas fuel injectors are installed on the intake manifold in almost all cases.
How do you install fuel injectors?
Install the new fuel injectors into the fuel pipe by twisting them into place so that the electrical connectors face away from the fuel pipe. Coat the injector bores in the cylinder head with light machine oil. Install the spacers and connect the fuel pipe to the cylinder heads.
What is the most common fuel injection system?
As technology advances, direct injection engines may become easier to manufacture, but, for now, sequential multi-port injection remains the most common fuel injection system in cars today. It provides the right mix of efficiency and affordability for most applications.
How does common rail injection work?
The common rail-fuel-injectors are controlled by the vehicle’s Engine Control Unit. When the injectors are activated by the ECU via a signal, a hydraulic valve made up of a plunger or nozzle, either hydraulically or mechanically, opens and sends fuel into the engine cylinders.
What is common rail direct injection?
Common rail. Common-rail direct fuel injection is a direct fuel injection system for diesel engines. On diesel engines, it features a high-pressure (over 100 bar or 10 MPa or 1,500 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles).
