Superior Vantage Engine O-360 SERIES Maintenance Manual page 22

Crankcase - The crankcase is made from
aerospace grade, stabilized structural aluminum
alloy. The assembly consists of two reinforced
aluminum alloy castings fastened together by
means of studs, bolts, and nuts.
bearing bores are machined for use with
precision type main bearing inserts.
Accessory Housing - The accessory housing is
made from an aluminum casting and is fastened
to the rear of the crankcase and the top rear of
the sump.
Oil Sump - The sump incorporates an oil drain
plug, oil suction screen, mounting pad for
carburetor or fuel injector, the intake riser, and
intake pipe connections.
Cylinders - Millennium
exclusively. These air-cooled cylinders are
manufactured by screwing and shrinking the two
major parts, head and barrel, together. The cast
heads are made from a special aluminum alloy.
All barrels are made from forgings produced to
aerospace specifications.
choked and honed to allow optimal operating
conditions for the rings and pistons at operating
temperatures.
Pistons - The pistons are made from an
aluminum alloy. The piston pin is a full floating
type with a plug located in each end of the pin.
The piston is a 3-ring type with 2 compression
rings and 1 oil control ring.
Cooling System – Superior Vantage Engines
are designed to be air-cooled.
provided to build up air pressure and force the
air between the cylinder fins.
exhausted to the atmosphere through the rear of
the cowling.
Induction System - The distribution of the air to
each cylinder is through the center zone of the
induction system. This is integral with the oil
sump.

Lubrication System - The full pressure wet
sump lubrication system is supplied by a gear
type pump. It is contained within the accessory
housing.
Priming System - A manual primer system is
provided on all engines using a carburetor. Fuel
injected engines do not require a manual
priming system, relying instead on the fuel
injectors for priming.
Ignition System - Dual ignition is furnished by
two Unison magnetos with two spark plugs per
cylinder.
Electrical System – Engines may be furnished
with an alternator, if provided for in the model
specification. If an alternator is furnished,
installation brackets, hardware and belt are
provided. Alternators are available in either 12
or 24 volt systems and a range of amperages
Fuel Systems
Carbureted - Superior Air Parts O-360 engines
are equipped with a float type carburetor The
MA-4-5 carburetors are of the single barrel float
type equipped with a manual mixture control and
an idle cut-off.
Fuel Injected - IO-360 series engines are
equipped with a direct cylinder injected RSA-5-
AD1 fuel injection system.
system schedules fuel flow in proportion to
airflow. Fuel vaporization takes place at the
intake ports. The RSA fuel injection system is
based on the principle of measuring airflow and
converting the air pressure into a fuel pressure.
The fuel pressure, when applied across the fuel
metering section, makes fuel flow proportional to
airflow.
