The TSIO-550-G has twin turbochargers which use exhaust gas flow to boost induction air pres-
sure for increased power. There is one turbocharger on each side of the engine. The turbocharg-
ers compress and raise the temperature of the incoming air before going to the intercoolers. The
compressed air runs through the intercoolers where it is cooled down before entering the throttle
body and cylinders. The dual turbochargers are lubricated from external oil supply lines from a
source at the bottom of the oil cooler. There is one oil pressure actuated wastegate on the left
side of the engine controlling the amount of exhaust gas used by the turbochargers. Control is
accomplished by a diaphragm actuated valve sensing differential pressure across the throttle
plate and controlling the oil return flow rate from the wastegate. An overboost valve in the induc-
tion system provides protection from too much pressure by actuating at 35 in Hg of manifold
pressure.
The engine operates with three, standard engine controls. The propeller turns clockwise as
viewed from the cockpit.
ENGINE CONTROLS
The engine controls are centrally located between the pilot and co- pilot on the lower middle in-
strument panel. The BLACK throttle knob regulates manifold pressure; push the knob forward to
increase the setting; pull the knob aft to decrease the setting.
The propeller control, with its crowned BLUE knob, controls engine RPM through the propeller
governor. Push the knob forward to increase engine RPM; pull the knob aft to decrease RPM.
The mixture control, with its RED fluted knob, establishes the fuel- air ratio (mixture). Push the
knob full forward to set the mixture to full- rich, pull the knob gradually aft to lean the mixture. Pull
the knob to its maximum aft travel position to close the idle cut- off valve to completely shutdown
the engine. Precise mixture settings can be established by observing the TIT gauge on the pilot’s
instrument panel while adjusting the mixture control.
The throttle, propeller and mixture controls are vernier type and fine adjustment can be made by
turning knobs clockwise or counter- clockwise. The vernier controls should be rigged within .030
to .060 in. from panel nut face. Rapid movement or large adjustments can be made by pushing
button on end of control and positioning control where desired. The non- vernier throttle has an
integral friction device.
ENGINE INSTRUMENTS
Engine instruments operate electrically, except manifold pressure, through variations in resis-
tance caused by pressure or temperature changes or by variations in current output caused by
varying engine RPM or alternator output. The tachometer receives its signal from the Hall effect
sensor in magneto.
