7) System Description

This chapter of the Operator Manual contains information about
the general engine specification as well as a description of
cooling system, fuel system, lubrication system, electric system
and the propeller gearbox.
The system description refers only to the engine and not to a
specific application in a particular aircraft. The aircraft
manufacturers Operators Manual is therefore definitive in terms
of the operation of the engine, as it contains all the aircraft
specific instructions.
The design shown in this chapter does not represent a
specified execution but should support the understanding of the
system.
