What is the CRDi system?

CRDi stands for Common rail direct injection which means the direct injection of fuel into the cylinder of a diesel engine through a single common line called common rail which is connected to fuel injectors.

Why CRDi is used?

Advantages of CRDI System: CRDI system can control the flow of fuel in accordance with the load and speed of the engine. This system requires only one fuel pump for multiple cylinders. CRDI system is beneficial for the environment as it reduces noise, smoke and particulate matter. It gives high power output at low rpm.

What are the mechanical parts of CRDi?

The system consists of a high-pressure pump, injectors, a rail, and an electronic control unit.

What is CRDi IC engine?

The term CRDi stands for Common Rail Direct Injection. The technology directly injects fuel into the cylinders of a diesel engine through a single, common line, known as the common rail. The common rail is connected to all the fuel injectors.

What is the basic principle of CRDi technology?

Barring some design changes, the basic principle & working of the CRDi technology remains primarily the same across the board. However, its performance depends mainly on the combustion chamber design, fuel pressures and the type of injectors used. The manufacturers use custom acronyms to make their diesel CRDi product stand out in the competition.

Who is the designer of CRDi engine system?

All the car manufacturers have given their own unique names to the common CRDi engine system. Sachin is a B-TECH graduate in Mechanical Engineering from a reputed Engineering college. Currently, he is working in the sheet metal industry as a designer. Additionally, he has interested in Product Design, Animation, and Project design.

How does common rail direct injection ( CRDi ) work?

CRDI stands for Common Rail Direct Injection. Direct injection of the fuel into the cylinders of an engine via a single, common line, called the common rail which is connected to all the fuel injectors. Instead of providing separate piston pumps for fuel supply, the common rail alone supplies high pressure fuel to each cylinder.

What is the difference between GDI and CRDi?

However, in diesel engines, manufacturers refer to this technology as CRDi whereas Petrol engines term it as Gasoline Direct Injection ( GDI) or Fuel Stratified Injection (FSI). Both these technologies have a similarity in design since they consist of “fuel-rail” which supplies fuel to injectors.
