What is the component of common rail injection system?
Abstract: The components of a common rail fuel injection system include the rail, a high pressure pump and fuel injectors. Radial, unit and in-line pumps are used in commercial common rail systems.
What are the components of diesel injection system?
The low-pressure components include the fuel tank, fuel supply pump and fuel filter. The high-pressure side components include a high pressure pump, accumulator, fuel injector and fuel injector nozzle.
What makes a common rail injector inject fuel?
Abstract: In the common rail system, fuel is distributed to the injectors from a high pressure accumulator, called the rail. The rail is fed by a high pressure fuel pump. The pressure in the rail, as well as the start and end of the signal that activates the injector for each cylinder are electronically controlled.
What is the main component of common rail engine?
The injector in a common rail system consists of the nozzle, an actuator for Piezo injectors or a solenoid valve for solenoid valve injectors, as well as hydraulic and electrical connections for actuation of the nozzle needle.
What is better common rail or direct injection?
A common rail is one of the most important components in a diesel and gasoline direct injection system. The main advantages of the common rail direct fuel injection can be summarized in reduction of exhaust and noise emissions, better fuel efficiency and improved overall engine performance.
How many types of common rail injection system are there?
Two common types include the unit-injection system and the distributor/inline-pump systems. While these older systems provide accurate fuel quantity and injection timing control, they are limited by several factors: They are cam driven, and injection pressure is proportional to engine speed.
What are the 5 components of fuel system?
Here are five components of a diesel fuel system, along with information about what they do.
- The Fuel Tank. A fuel tank must have the ability to store enough fuel to keep the engine operational for a reasonable amount of time.
- The Fuel Lines.
- The Diesel Fuel Filters.
- The Diesel Fuel Pumps.
- The Fuel Injectors.
Is common rail better than direct injection?
Why are common rail injectors so expensive?
Injectors have a tolerance of 1 micron, the finest tolerance of any mechanical component on the engine. To be able to manufacture at such precise standards and to afford the exacting quality checks along with it also helps to explain part of the costs of quality fuel injectors.
What are the main component of the fuel system?
The fuel system is made up of the fuel tank, pump, filter, and injectors or carburetor, and is responsible for delivering fuel to the engine as needed. Each component must perform flawlessly to achieve expected vehicle performance and reliability.
What kind of fuel rail does a diesel engine use?
Both petrol and diesel engines use a common ‘fuel-rail’ which supplies the fuel to injectors. However, in diesel engines, manufacturers refer to this technology as CRDi whereas petrol engines term it as gasoline direct injection or fuel stratified injection.
How is the diesel injector connected to the rail?
It is installed in each engine cylinder and connected to the rail via a short high-pressure pipe. The injector is controlled by the electronic diesel control. This ensures that the nozzle needle is opened or closed by the actuator, be it solenoid valve or Piezo.
What are the advantages of common rail direct fuel injection?
The main advantages of the common rail direct fuel injection can be summarised in reduction of exhaust and noise emissions, better fuel efficiency and improved overall engine performance. The system consists of a high-pressure pump, injectors, a rail, and an electronic control unit.
What kind of fuel injectors are used in diesel cars?
We offer a variety of new and remanufactured fuel injectors including the latest common rail injectors. Manufacturers we reguarly provide for include Isuzu, Hyundai, Mazda, Alfa Romeo, Volkswagen, Mitsubishi and more. Diesel Engine Parts Diesel Center feature a wide range of engine parts for diesel vehicles, including 4WDs, tractors and boats.
