Six-Cylinder Electronic Ignition System Is Moving Rapidly Towards STC Approval
By Tom Woodward
Electroair produces a certified electronic ignition system for 4 cylinder engines and now is close to STC approval for 6 cylinder engines. Differing from other electronic ignitions systems which produce a very high voltage spark over a short time span, Electroair produces a spark of 70,000 volts thru 20 degrees of crankshaft rotation providing a more even, thorough burning of the fuel. One benefit of a longer fuel burn is the temperatures are retained longer to assist in the cleaning and extended life of the valves.
"We received approval for our electronic ignition system to be installed on the Aviat Husky" says Michael Kobylik, President of Electroair. In addition a single STC covers many aircraft equipped with certain engine configurations. Check with Electroair to see if your airplane qualifies.
Electroair claims that their ignition system will give pilots:
- More horse power
- smoother operation
- improved high altitude performance
- reduced maintenance
- longer spark plug life and less fouling
- 10-15% gain in fuel efficiency
Electroair started business in 1992 and currently has over 3000 systems installed. A typical installation is to replace one magneto with an Electroair Electronic unit. 85% of the benefits are achieved with one unit. Those who fly at high altitudes, above 17,000 feet utilizing pressurized magnetos, could gain an additional 15% with the installation of the second unit.
Electroair is also sponsoring Spencer Suderman and his world record attempt at the greatest number of inverted flat spins utilizing his Pitts Special. The Electroair ignition will help him achieve the necessary altitude to achieve this record.
STC approval of the electronic ignition for the 6 cylinder engine is moving along at a brisk pace. Testing is now complete on the O/IO-470 and the IO-520. The testing shows a typical fuel savings of between 1.5 to 2.0 gph.
