Due to the high injection pressures involved in a Common Rail system, the cleanliness of fuel is very critical. One of the most important system components is the fuel filter which acts as the engines' first line of defence.

Effective filtration and Diesel fuel conditioning are essential to protect the Common Rail Fuel Injection Equipment (FIE) from water and particle contamination. As little as 2 microns of dirt can completely wear out a fuel pump.
 
Delphi Diesel's latest range of fuel filters has been developed to remove particles down to as little as 2 microns. Further enhanced features ensure that demands for long life and improved performance are still met.

As with traditional filters, Delphi Diesel are fitted as original equipment on a number of Common Rail applications, including Renault, Ford, Kia, Hyundai, PSA, Jaguar and SsangYong. For the full list of Common Rail filters available.

Common Rail Filters from Bosch are optimised for high injection pressures and low tolerances of the Common Rail precision technology. The double-layer filter medium of polyester and cellulose enables an extremely high absorption of dirt and the highest separation grades. The filter construction with a radial vee-form filter element results in maximum water separation. As a result of the knowhow of Bosch, the diesel systems developer, it is guaranteed that the Common Rail filters are precisely tailored to the respective engine and meet the highest requirements of performance and service life.

Advantages/ Benefits

  • Integration of water separation, fuel heating and fuel cooling in one module
  • Pressure stability also with very high injection pressures
  • Special filter media achieve high storage capacity and separation of finest particles
  • Effective water separation from the fuel prevents corrosion damage
