What is Common Rail Direct Injection (CRDI)? The common rail direct injection or CRDI system is an advanced technology used where the highly pressurized fuel is supplied through a common rail to injectors in a diesel engine. This system stores fuel in a common rail at higher pressure by allowing efficient and precise fuel delivery to every cylinder. It uses a central fuel rail to stock up fuel.. The document discusses Common Rail Direct Injection (CRDi) technology used in modern diesel engines. CRDi uses a high-pressure fuel pump to pressurize fuel and deliver it to a common rail fuel line. From there, precisely metered solenoid injectors inject the fuel directly into the combustion chamber. This allows for more control over injection timing and quantity compared to older diesel.

The document summarizes the components of a common rail direct injection (CRDI) fuel system. It describes the low pressure fuel circuit which includes a fuel pump, fuel filter, and fuel sender. It then describes the high pressure fuel circuit, including a high pressure fuel pump that compresses fuel and sends it to a common rail for storage, from which injectors inject the fuel into cylinders.. CRDi engine | Working Of Common Rail Diesel injection System Notes on Common Rail Direct Injection (CRDi) The term 'CRDi' commonly refers to diesel engines. Although, there is a similar technology which the petrol engines also use it is known as Gasoline Direct Injection (GDI) or Fuel Stratified Injection (FSI). Both these technologies have a similarity in design since they consist of a.
