UL350iS

The engines feature FADEC (full authority digital engine control) with multi-point electronic fuel injection, and dual electronic ignition (with variable timing), excellent power-to-weight ratio, and high fuel efficiency in a conventional configuration: Air-cooled, direct drive, horizontally opposed four-cylinder.

UL Power Engines have been developed specifically for use in light aircraft and are manufactured with fully electronic ignition and multi-point fuel injection (FADEC) system as standard equipment.

  • Four-stroke, air cooled, four-cylinder opposed engine
  • Dual (redundant) electronic spark ignition (variable timing)
  • Multi-point 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
  • Electric fuel pump and pressure regulator to eliminate vapor lock and facilitate starting even under adverse conditions.

UL Power engines are manufactured in Europe.
