Zenith and UL Power Announce Firewall Forward Kit
Zenith Aircraft Company and UL Power North America LLC announced the availability of complete firewall forward kits for the CH 650 kit aircraft. The firewall forward package includes the direct-drive, air-cooled, UL350iS aircraft engine. The 130-hp powerplant is a horizontally opposed, four-cylinder, four-stroke engine with FADEC. The full firewall forward kit includes everything builders need to install the engine in their Zenith airframe, including engine mount, oil cooler, fuel pumps, propeller and spinner, and fiberglass cowl.
UL Power is a modern new line of four-cylinder, direct-drive, air-cooled light aircraft engines from Europe with FADEC, which stands for Full Authority Digital Engine Control. In UL Power's case it means that the ECU (engine control unit) controls all aspects of the engine performance and decides on the amount of fuel it injects into the inlet ports as well as the exact timing of the spark advance.
The design of this new line of engines features dual (redundant) electronic spark ignition (variable timing), multi-point electronic fuel injection with automatic altitude and temperature compensation, wet sump forced lubrication with integrated pressure regulator, and ram air-cooled cylinders and cylinder heads. An electric fuel pump with a pressure regulator eliminates vapor lock and facilitates starting even under adverse conditions. Several models are available ranging in power from 97 to 130 hp.
The complete firewall forward package developed and supported jointly by Zenith and UL Power is available directly through Zenith Aircraft Company, and can be shipped with the airframe kit or at a later date. Contact Zenith Aircraft for more details. The kit for the UL350iS engine installation in the CH650 is available now and will be followed shortly by a kit for the STOL CH 750, which has the same firewall. “We’ve been flying our factory demonstrator CH650 with the 130-hp UL350iS for a few months now and we’re extremely pleased with the performance and operation of this engine,” said Sebastien Heintz, president of Zenith Aircraft Company.
