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.

UL Power engines are manufactured in Europe.

The UL260iF is specially dedicated to the French market. The engine is based on the UL260iS and specially adapted to be compliant with the French ULM (ultralight) regulations.

On 7 October 2013 the first Europa (G-BWUP) to be fitted with a UL Power UL260iS 107 Hp engine flew for the first time from a Private strip in Wiltshire, UK. With the test pilot going up for a 30 min first flight and no real probs reported apart from the Constant speed prop needed adjusting. The second flight was a little shorter but the Prop was working well now and the take off roll with one up and half fuel and nil wind was only 220 meters.
