Symptoms of a faulty Common Rail injector?
- Check engine light: if the engine is not performing as it should, it can trigger the engine management light to come on.
- Rough idle: if fuel delivery is restricted, the RPM at idle will drop resulting in a rough idle.
How does common rail direct injection engine works?
The CRDi technology works in tandem with the engine ECU, which gets inputs from various sensors. It then calculates the precise quantity of fuel and timing of injection. In the CRDi system, the fuel-rail constantly stores and supplies the fuel to the solenoid valve injectors at the required pressure.
How does common rail system work?
HOW DOES THE COMMON RAIL SYSTEM WORK? The high pressure pump pressurizes the fuel and transfers it to the rail, a common conduit that serve as pressure accumulator and reservoir. The pressure is regulated by an electronically controlled valve, so that the rail maintains the correct pressure required by the ECU.
How long do common rail injectors last?
The average lifespan of a diesel fuel injector is around 100,000 miles. A typical fuel injector has two basic parts: the nozzle and the injector body. If either of these components gets clogged or damaged, it will compromise the entire performance of the vehicle.
How do you know if diesel injectors are bad?
Here are the 5 most common symptoms of faulty diesel fuel injectors. Trouble starting the vehicle or uneven idling. The engine cranks but doesn’t start unless you crank it for a long time. The engine is using different speeds of revs on idle.
How are the injectors activated in a modern common rail fuel injection system?
How are the injectors activated in a modern common rail fuel injection system? Explanation: The fuel injectors present in the modern common rail fuel system are activated by the solenoid valve. Solenoid valves and the fuel pump are electronically controlled.
What pressure does a common rail diesel run at?
29,000 PSI
Common rail direct fuel injection is a direct fuel injection system for petrol and diesel engines. On diesel engines, it features a high-pressure (2,000 BAR – 29,000 PSI) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors or pump nozzles.
What type of injectors are used in a common rail fuel injection system?
Common rail systems can use one of several injector designs: servo controlled electrohydraulic injectors, servo controlled electrohydraulic injectors incorporating pressure amplification, or. direct acting injectors.
What is diesel common rail direct (CRD) injection?
Diesel common rail direct injection (CRDI) and its benefits 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.
How do you replace fuel injectors?
Scan the computer system in the car for codes. Visually inspect injectors for any signs of fuel/gas leakage. If accessible, OHM test each injector. Remove and replace the injector if it is bad. Replace the fuel filter it is not inside the fuel pump. Replace the plenum gasket. Inspect for fuel leakage. Clear diagnostic information.

What is a CRDi engine?
CRDI means Common Rail Direct Injection. CRDI engine contains a small tube called Common rail where the injectors are connected and contains fuel at a constant high pressure of 1,350 bars. The CRDI engine small amount of fuel into the engine before the actual charge and another one afterwords.
