PowerLink™ is a solid-state digital
electronic system with only one moving part, the pintel that moves
in the fuel injectors at each cylinder. From the precision casting
of the controller housings to the CNC machining of speed sensor
assembly parts to the laser welding of the solenoid coil enclosures,
the system showcases the latest developments in manufacturing.
All of the electronic circuit boards are manufactured on an automated,
environmentally clean chemical production line. Placement of electronic
components is automatically registered then surface-mount wave-soldered
to the printed circuit board.
Featuring a unique control architecture, our PowerLink™ FADEC
system provides a computer per engine cylinder for precise control
of spark ignition and fuel injection firing events over the entire
operating envelope. SINGLE-LEVER CONTROL is the
result, so the pilot only needs to think the throttle setting. Carburetor
heat, mixture, and priming are eliminated, and even prop controls
can be eliminated. Engine operation is smooth, optimal, and closed-loop
self regulating.
Waste spark ignition is included in FADEC, which keeps plugs cleaner
longer. Computers control the charging of individual spark coils
to provide hot, high-energy sparks throughout engine operation.
IGNITION TIMING is varied by the computer to ensure
easy starting and maximum rated engine power availability whether
in takeoff, roll, climb, or economy cruise conditions.
In dynamic engine operation, environmental conditions and component
performance change. AUTOMATIC SELF-CALIBRATION
is included in PowerLink™ FADEC in which computers automatically
and continually correct for changes in critical measures such as
temperature, fuel pressure, and input voltage. In addition, computers
always find the best operating point for fuel economy and power.
Our advanced design includes SEQUENTIAL PORT FUEL INJECTION
at each engine cylinder. Each fuel injector is solenoid operated
under precise computer control, to ensure correct mixture for each
firing event under all operating conditions. The amount of metered
fuel matches the cylinder air charge, whether operating at best
power or best economy conditions. Guesswork in setting fuel-air
mixture is a thing of the past.
PowerLink™ FADEC utilizes an array of engine data in calculating
the correct spark timing and fuel mixture. Data include cylinder
head and exhaust gas temperatures, speed, camshaft position, fuel
and manifold pressure, and air temperature. For each ignition event,
DENSITY ALTITUDE COMPENSATION is included based
on the current manifold temperature, pressure, and engine speed.
We've taken the guesswork out of engine operation, maintenance,
and diagnostics. PowerLink™ FADEC provides an ENGINE
DIAGNOSTIC PORT so you can download vital engine data onto
a hand-held terminal or laptop computer. With our diagnostic software
package, detailed analysis of engine performance is available for
use in troubleshooting, maintenance, and determining performance
trends.
A DIGITAL, CLOSED-LOOP ENGINE CONTROL SYSTEM provides
individual cylinder control, peak torque ignition timing, sequential
fuel injection, cylinder temperature control, automatic self-calibration,
annunciation of health status, and serial engine performance data.
