UL Power Aero Engines

CH 650 with UL Power
UL Power is a modern new line of light aircraft engines from Europe featuring four cylinders (direct drive, air-cooled) with FADEC, and presents unique sought-after features, making UL Power an excellent light aircraft engine choice.

UL Power

ULPower engines, represented in North America by UL Power North America LLC, have been developed specifically for use in light aircraft and are manufactured to the highest standards with fully electronic ignition and multi-point fuel injection (FADEC) system as standard equipment, with several lightweight models ranging in power from 97 - 130 hp, making them an excellent choice to power the two-seat Zenith kit aircraft models.

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

  • Modern Technology 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
  • High fuel efficiency
  • No carburetor icing problems
  • Excellent power to weight ratio
  • Electric fuel pump and pressure regulator to eliminate vapor lock and facilitate starting even under adverse conditions

Contact Zenith Aircraft Company directly for the latest pricing and availability information.  Currently, the complete firewall forward package is available from Zenith Aircraft Co. for the UL350iS engine installation in the CH 650, to be followed shortly by the STOL CH 750 (as the two aircraft models share the same firewall).  Since the UL Power engine is imported from Europe engine prices fluctuate on a regular basis due to currency exchange.

Alternative engines will affect performance, specifications and flight characteristics of the aircraft. Also, the weight and balance of the aircraft may be adversely affected by alternative engines, and the original fuel system may not be adequate or suitable for some engines. Most alternative engines will require a custom engine mount and engine cowl. Zenith Aircraft Company does not manufacture or directly support engines installed in kit aircraft.
