Bosch Common Rail Technology

From the world leader of diesel fuel system design

Key Features

The common rail system is a major advancement in diesel technology. Bosch launched its common rail system for passenger car diesel engines in 1997. Today, Bosch is the world leader in diesel fuel system design and the OE supplier for 100% of class 1-3 light duty vehicles in North America.


Common rail technology provides diesel engines with:

  • Quieter performance
  • Clean, highly efficient fuel injection
  • Improved fuel economy
  • Higher torque
  • Lower emissions


Bosch manufactures two types of injectors for common rail – solenoid and piezo. Bosch injectors are the standard for the industry and provide superior performance and durability under most operating conditions.


Bosch diesel fuel injectors fall into three categories:

  • Bosch genuine OE injectors
  • Bosch remanufactured OE injectors
  • Workshop injectors that are rebuilt by an authorized Bosch Common Rail Field Repair location
