introducing e-mag

E-MAG is a full-featured electronic ignition upgrade that includes a simple and elegant built-in power supply solution.

The Power of E-MAGination

It’s surprising to many that traditional mechanical magnetos are still the industry standard aircraft ignition. The reason is simple but significant. Magnetos have one important property that makes them so attractive and appropriate for aviation. They make their own electrical power. They’re immune to interruption of the aircraft electrical bus. Their down-side is they produce limited spark energy and they have fixed timing. But in terms of independent power – magnetos have it right.

 

“I love the fact that they are self energizing like standard magnetos, and can stand alone from the aircraft’s electrical system. Timing them is so easy it’s hard to believe.” Danny King,  flying (and with his) “Beautiful Doll”, DUAL E-MAGs

Efficiency

Most electronic ignitions are the polar opposite – in terms of features. They have greater spark energy as well as variable spark timing. These two basic changes can improve efficiency (fuel consumption) in the range of 10% to 15%. As impressive as that is, all electronic ignitions share one critical vulnerability. Unlike magnetos, electronic ignitions are dependent on a functioning power supply.

 

“Timing is so easy that my ‘magneto’ friends just shake their heads and smile.” Steve Emley, flying Long EZ with DUAL E-MAGs

Essential Redundant Power

E-MAG’s are the exception. They have a purpose-built electronic ignition, mated with a built-in permanent magnet alternator. E-MAGs automatically shift between the internal alternator and external (aircraft bus) power as needed – no operator action required. With two sources of operating power, E-MAGs have the kind of electrical redundancy that’s so desirable [essential] for aviation applications. A dual E-MAG installation is actually triple redundant, and does not require supplemental emergency power provisions (i.e., no need to keep an old-fashion magneto).

No single change will require as little time, as little effort and as little investment – and have as much effect on performance, economy and reliability as upgrading to electronic ignition!

After installing DUAL E-MAGs (RV4, O-320) . . .  “The efficiency improvement becomes dramatic when leaned for normal cruise. At 75 percent power (23.5 inches manifold pressure, 2,400 rpm, and 145 KIAS), fuel flow settles at 8 gph (down from 9.0 gph with mags). At a more economical 65 percent power (22 inches mp, 2,200 rpm, and 135 KIAS) fuel flow drops all the way to a miserly 6.0 gph.”
