What are the main components of CRDi?
Components of CRDi
- Fuel injection pump – pressurizes fuel to high pressure.
- High-pressure pipe – sends fuel to the injection nozzle.
- Injection nozzle – injects the fuel into the cylinder.
- Feed pump – sucks fuel from the fuel tank.
- Fuel filter – filtrates the fuel.
- Engine control unit.
What is common rail engine technology?
Common rail is a fuel injection system found in modern diesel engines. In common rail systems, the fuel is supplied to the engine under pressure with electronically controlled precision. This provides a level of flexibility which can be exploited for class leading levels of emission control, power and fuel consumption.
What is CRDi technology?
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.
Do common rail injectors need coding?
DENSO Common Rail injectors – generally all require coding, although some very early versions may not. A typical code length is 16-24 alphanumeric characters depending on the vehicle make. The code is usually found on the injector connector. You can also use the QR code found on the injector for this information.
How does a common rail 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 do common rail diesels work?
What is DDiS engine?
DDiS, or Diesel Direct Injection System is the designation for Suzuki diesel engines with Common Rail direct injection system. Usually, engines are equipped with variable geometry turbochargers and intercoolers. To date, all DDiS engines have 4 cylinders arranged in a line.
What is MPFI system?
The MPFI is a system or method of injecting fuel into internal combustion engine through multi ports situated on intake valve of each cylinder. It delivers an exact quantity of fuel in each cylinder at the right time.
What does zero quantity calibration mean?
Zero calibration requires removing any trace of the target gas or any other cross-sensitivity gases from the sensor, to provide the instrument with a baseline reading when no gas is present*
What is MPFI engine?
What is multi point fuel injection (MPFI) system? The MPFI is a system or method of injecting fuel into internal combustion engine through multi ports situated on intake valve of each cylinder. It delivers an exact quantity of fuel in each cylinder at the right time.
