SECTION 1
Cooling
System - These
engines are
designed to be
cooled by air pressure.
Baffles
are provided to build up a
pressure and force the air through
the
cylinder
fins. The air is
then exhausted
to the atmosphere
through gills
or
augmentor
tubes
usually
located
at the rear
of the
cowling.
Induction
System
Lycoming
0-360 and
HO-360
series engines
are
equipped
with either
a float
type
or pressure
type
carburetor.
See
Table
1
for model application.
Particularly good distribution
of the fuel-air
mixture
to each
cylinder is
obtained
through the
center
zone induction
system, which
is integral with
the oil sump
and is submerged
in oil,
insuring a more
uniform vaporization
of fuel
and aiding in
cooling the oil
in the
sump. From
the riser the fuel-air
mixture
is distributed
to each
cylinder
by individual
intake pipes.
Lycoming 10-360,
AIO-360, HIO-360 and TIO-360
series engines
are
equipped with
a Bendix type
RSA fuel injector,
with the exception
of
model 10-360-B1A
which is equipped with
a Simmonds type 530 fuel
injector. (See Table 1 for model application.) The fuel injection system
schedules fuel
flow in proportion
to air
flow and fuel vaporization
takes
place
at the intake ports. A turbocharger
is mounted as an integral
part of
the TIO-360 series engines. Automatic waste gate control of the
turbocharger provides constant air density to the fuel injector inlet from
seal level to critical altitude.
A brief description of the carburetors and fuel injectors follows:
The Marvel-Schebler MA-4-5 and HA-6 carburetors are of the single
barrel float type equipped
with a manual mixture control
and an idle
cut-off.
The Marvel-Schebler MA-4-5AA carburetor is of the single barrel float
type with automatic pressure altitude mixture control. This carburetor is
equipped with
idle cut-off but does not have
a manual mixture control.
The Bendix-Stromberg
PSH-5BD is a
pressure operated, single barrel
horizontal
carburetor, incorporating
an airflow operated power
enrichment valve and an automatic mixture control unit. It is equipped
with an idle cut-off and a manual mixture control. The AMC unit works
independently of, and in parallel with, the manual mixture control.
