SECTION 7 CESSNA
AIRPLANE & SYSTEMS DESCRIPTION MODEL 182T
EXHAUST SYSTEM
Exhaust gas from each cylinder passes through riser assemblies
to a muffler and tailpipe. Outside air is pulled in around shrouds
which are constructed around the outside of the mufflers to form
heating chambers which supply heat to the cabin.
FUEL INJECTION SYSTEM
The engine is equipped with a fuel injection system. The system
is comprised of an engine-driven fuel pump, fuel/air control unit, fuel
manifold, fuel flow indicator, and air-bleed type injector nozzles.
Fuel is delivered by the engine-driven fuel pump to the fuel/air
control unit. The fuel/air control unit correctly proportions the fuel
flow to the induction air flow. After passing through the control unit,
induction air is delivered to the cylinders through the intake manifold
tubes and metered fuel is delivered to a fuel manifold (flow divider).
The fuel manifold, through spring tension on a diaphragm and
valve, evenly distributes the fuel to an air-bleed type injector nozzle
in the intake valve chamber of each cylinder. A fuel flow transducer
is also installed upstream of the fuel/air control unit which attaches
to the rear baffle, and is connected to a fuel flow indicator on the
instrument panel.
COOLING SYSTEM
Ram air for engine cooling enters through two intake openings in
the front of the engine cowling. The cooling air is directed around
the cylinders and other areas of the engine by baffling, and is then
exhausted through an opening at the bottom aft edge of the cowling.
The cowl flaps are mechanically operated from the cabin by means
of the cowl flap control on the right side of the control pedestal.
