This section contains an explanation of the units that make up each of the systems that bring fuel, air, and ignition together in an aircraft engine for combustion. It also contains information on engine construction features, lubrication systems, exhaust systems, cooling systems, cylinder removal and replacement, compression checks, and valve adjustments. Because there are so many different types of aircraft in use today, it is reasonable to expect that differences exist in airframe components and systems. To avoid undue repetition, the practice of using representative systems and units is carried out throughout. Subject matter treatment is from a generalized point of view and should be supplemented by reference to manufacturer’s manuals or other textbooks if more detail is desired. This section is not intended to replace, substitute for, or supersede official regulations or the manufacturer’s instructions.
