ULPower engines overview

Introduction to ULPower aero engines

ULPower Aero Engines developed this engine specifically for use in light aircraft (fixed wing & rotorcraft). It is built to the highest standards with a fully electronic ignition and multipoint fuel injection (FADEC) system as standard.

The design of this engine was based around critical issues such as reliability, light weight, excellent performance, a direct propeller drive and modern, proven technology.

  • Modern Technology 4 stroke, air cooled, 4 cylinder opposed engine
  • Dual (redundant) electronic spark ignition (variable timing)
  • Multipoint electronic fuel injection with automatic altitude and temperature compensation
  • Electronic RPM limiter
  • Direct propeller drive
  • Wet sump forced lubrication with integrated pressure regulator
  • 5 bearing crankshaft with thrust ball bearing
  • Ram air cooled cylinders and cylinder heads
  • High fuel efficiency
  • No carburettor icing problems
  • Excellent power to weight ratio
  • Electric fuel pump and pressure regulator to eliminate vapor lock and facilitate starting even under adverse conditions
