Diesel System Components

The geometry and characteristics of Diesel engine components are more dependent upon the application than those for gasoline engines. A single injector design will not fit all Diesel engines due to varying mechanical and nozzle geometry requirements. In addition, the injection system can vary from year to year even within the same make of car.

Bosch Motorsport uses the same Common Rail technology for racing that was developed for production vehicle applications. This includes both solenoid (magnetic) technology and the latest cutting-edge piezo technology.

Bosch Motorsport can offer a wide variety of modifications to fit the system to your specifications. These modifications include:

  • Definition of suitable base components from other (or larger) engine applications.
  • Adaptation of components for mating, fit and orientation to suit the selected application.
  • Flow enhancement of injectors and rails.
  • Injector nozzle adaptation (flow rate, number of holes, spray cone angle etc.).




  • Modification of Common Rail systems
  • Different modification levels available
  • All hydraulic parts available

Installation Notes

When contacting us for more information on our Diesel components, please have the following information ready so that we may best determine components required for your application:

  • The base engine / the car where this engine originally is installed
  • Model year and type of car / engine
  • The base output level and the desired output level for the engine
  • If it is originally equipped with Bosch components: the part numbers of the Bosch components
  • Alternatively the car / engine manufacturer part number of the original injection system.
