Vittorazi Cosmos 300 EFI

One of light aviation’s most popular engines will soon be available with electronic fuel injection.

Vittorazi displayed its Cosmos 300 EFI for the first time this week at Sun ‘n Fun.

The carbureted version of the 36 horsepower two-stroke is a favorite for PPG applications. Vittorazi’s team leader and developer for the EFI version, Santino Genovese, says the company focused on adding to what made the carb version so great.

“Simplicity was our goal,” Genovese said. “Not only for the EFI unit of the engine, but for the user too.” To this end, Genovese points to the engine’s ability to recognize when it’s being started ‘cold,’ and that it’s probably not a good idea for the throttle to be forward very far at that point.

“With this engine there won’t be a runaway trike or a paraglider knocked down because the throttle was mistakenly set at full during startup,” explains Genovese.

The EFI unit can also feed data through the on/off switch to the pilot. The included gauge displays EGT, CHT, and battery readings, as well as fuel quantity, time left in flight and Hobbs info, among other data.

Vittorazi dealer Kris Harrington says the EFI system really adds to ease of starting at any altitude or temperature, and to engine reliability and serviceability. “Pilots will be able to send engine data to us if there ever are issues because the EFI records what happens,” Harrington said.

EFI also makes the engine more fuel efficient according to testers. One pilot reported using 40% less fuel on longer flights. Pricing for the new engine was not available at this time. Vittorazi says deliveries should start early in 2025.
