This is a four-stroke-cycle diesel engine that consists of four cylinders installed in line with four valves each. This turbocompressor liquid-cooled engine is provided with the reducing gear having the reduction ratio i = 1.69:1. The following embedded systems improve its performance:

  • COMMON RAIL direct injection system
  • all-electronic engine and propeller control system
  • wet-sump lubrication system

CENTURION 2.0 engines are approved by the European Aviation Safety Agency (EASA) and Federal Aviation Administration (FAA). CENTURION 2.0 has EASA and FAA supplemental type certificate for the following aircraft models: Cessna-172 and Piper PA28. Diamond Aircraft Industries also installs CENTURION 2.0 engines into its aircraft, models DA40 TDI, DA42 Twin Star, while Apex Aircraft installs them into Robin DR400 models.
