Ameritech offers Electroair electronic ignition system

Ameritech Industries, the parent company of Eagle Engines and American Propeller, now offers the Electroair Certified Electronic Ignition System for Lycoming O, IO and AEIO-540 six cylinder engines.

This series of approvals follows 30 days after the approval of the Continental O/IO-470 and IO-520 systems. Ameritech is a stocking distributor for Electroair and systems are on the shelf, ready-to-ship, company officials said.

Electroair 540 ignition system copyThe EIS-61000-5C is an FAA/PMA’d ignition system that is currently STC’d and approved for Cessna, Bellanca, Piper, Maule, Extra, Pitts, Siai Marchetti, Socata, Dornier, Britten-Norman Trislander and Helio aircraft with models being added regularly.

The Electroair direct fire ignition system replaces one magneto with a Crankshaft Trigger Wheel (CTW), which feeds the engine position and RPM information to the controller. The controller also receives the input from the MAP sensor, computes the amount of dwell, adjusts timing, and signals the coils to fire directly into the spark plugs.

As a result, you will gain 10-15% in fuel economy, smoother engine operation, improved high altitude performance, improved horsepower, reduced hot start problems, reduced spark plug fouling and reduce maintenance costs at 500 hour intervals and at engine overhaul, according to company officials.

Additional CTW systems are in development for the Continental O-300, IO-360, TSIO-360, IO-550, TSIO-520 and TSIO-550, along with systems for the Lycoming TIO-540 engines.

Further, a Magneto Timing Housing (MTH) style system for most Continental engines is in development. The MTH style system will have no restrictions for clearances or deice being installed.
