Understanding common rail fuel systems

Reducing particulates and optimising fuel consumption are primary reasons for adding high pressure common rail (HPCR) systems to an engine. The HPCR is used in diesel engines across our range, providing improved fuel efficiency through a more efficient combustion process.

What do HPCR fuel systems do?

Fuel is distributed to the fuel injectors from a high pressure accumulator, called the rail, which isfed by a high pressure fuel pump. Rail pressure and injection timing are electronically controlled.

HPCR fuel systems can provide a cleaner and more fuel efficient combustion process with improved performance, fuel efficiency and particulate matter reduction.

What are the strengths of HPCR fuel systems?

HPCR fuel systems improve engine performance through more efficient combustion and can be more fuel efficient than other systems.

Due to stable pilot injections, your engine will be quieter and produce fewer nitrogen oxides(NOx), reducing the aftertreatment requirements to meet various global emission standards.

Fast facts

A high pressure common rail:

  • Is a very common fuel system at Stage IV/Tier 4 Final
  • Optimises fuel consumption and reduces particulate emissions
