EXHAUST SYSTEM
Exhaust gas from each cylinder passes through a riser or exhaust
collector assembly (on the left or right side below the engine) to a
(muffler and overboard through a single tailpipe. Outside air is
supplied to a shroud constructed around the outside of each muffler
to form a heating chamber. The air heated by the muffler shrouds
is then supplied 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,
fuellair control unit, fuel
manifold, fuel flow indicator, and air-bleed type injector nozzles.
Fuel is delivered by the engine-driven fuel pump to the
fuellair
control unit. The fuellair 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 turbine-type fuel
flow transducer mounted between the
fuellair control unit and the
fuel distribution unit produces a digital signal that displays fuel flow
on the EIS pages.
