9. ENGINE CONTROLS
Some manually operated controls are required
to operate a Superior Vantage Engine. These
include mechanical controls, electrical controls
and fuel controls.
A. Throttle and Mixture Control
Mechanical controls are required to actuate the
throttle and mixture levers for both carbureted
and fuel injected Superior Vantage Engines.
Many methods may be used to accomplish this
as long as the following issues are addressed.
(1.) Individual controls are supplied for throttle
and mixture levers.
(2.) The control allows the throttle lever to
contact the idle stop screw.
(3.) The control allows the throttle lever to reach
“full open”.
(4.) The control allows the mixture lever to
contact the idle cutoff stop.
(5.) The control allows the mixture lever to reach
“full rich”.
(6.) Superior recommends that the “full open”
throttle position and “full rich” mixture position be
limited by the forward motion of the control and
not the lever touching the stop on the carburetor
or fuel injector servo. This is to prevent binding
and excessive compression within the control
itself should the lever hit its stop before the
control hits it full forward potential.
(7.) Superior recommends a vernier style
mixture control for improved control during
leaning.
(8.) The control does not bind or have “slack” so
as to cause delays in response during actuation.
(9.) Control cables should be the minimum
possible length, avoiding loops or “S-turns”.
(10.) Control cables should be securely fastened
at both ends and at intermediate points to
prevent excess vibration and improve
responsiveness.
(11.) Superior recommends the use of ball joints
or similar apparatus at the lever attachment
points to eliminate the potential for binding
during actuation.
B. Propeller Control
A mechanical control is required to actuate the
propeller governor for installations with constant
speed propellers. The control design should
address the same issues as listed above for the
throttle and mixture controls.
C. Ignition and Starter Switch
An electrical switch or switches must be
provided to control each magneto. This
switch(s) must be capable of opening and
closing the P-lead grounding circuit for each
magneto and must provide capability to check
the operation of each magneto individually
.
An electrical switch must be provided to engage
the engine starter. Superior recommends that
this be a momentary switch to prevent the
possibility of leaving the starter engaged for long
periods of time.
