  refactoring: avoid variable name 'engineSpeed' -> angularSpeed/angularVelocity; avoid Formulas.TorqueToPower/PowerToTorque
  visibility of CombustionEngineData in CombustionEngine
  adapting result data for unit-test 'FullLoadJump' to reflect changes in ComubstionEngine: DynamicFullLoadPower >= StationaryIdlePower
  update complexity metrics
  adding unit test code coverage results
