What are common rail injectors?

Common rail is a fuel injection system found in modern diesel engines. Common rail systems provide a level of flexibility which can be exploited for class leading emission control, power and fuel consumption.

Are all common rail injectors the same?

Non-OEM Fuel Injectors. One of the most common asked questions we get is: “Are injectors built to OEM standards different from regular injectors?” The short answer is yes. Common rail fuel injectors are not all made the same, just like not all diesel engines are the same.

How does a common rail fuel pressure sensor work?

It is a part of vehicle’s fuel system and designed to monitor the fuel pressure that is present at the fuel rail. The sensor sends this signal to the ECU, which then uses it to make adjustments to the vehicle’s fuel and timing. When the sensor has an issue it can cause problems with the performance of the vehicle.

Is common rail a unit injector?

Common rail injectors utilize a high-pressure fuel rail that provides fuel to the individual injectors. Unlike with unit injectors, the rail maintains the fuel at a constant, high pressure that is necessary for injection.

What is common rail technology?

Common rail technology is a digitally controlled, high-pressure fuel injection and sensor system that optimizes engine efficiency & performance. This results in reduced emissions, minimal noise, and peak power output, significantly improving the engine’s overall efficiency and comfort onboard.

What are the two types of injectors?

There are basically two types of non-hydraulic common rail injectors — electromechanical solenoid base and Piezo. Piezos are typically found on newer applications, depending on the vehicle.

What are the types of injector?

The fuel injection types used in newer cars include four basic types:

  • Single-point or throttle body injection.
  • Port or multipoint fuel injection.
  • Sequential fuel injection.
  • Direct injection.
