  • Chapter 1: Aircraft Engines › Types of Engines

    Reciprocating and gas turbine engines also have subdivisions based on the type of cylinder arrangement (piston) and speed range (gas turbine). Many types of reciprocating engines have been designed. However, manufacturers have developed some designs that are used more commonly ... than others and are, therefore, recognized as conventional. Reciprocating engines may be classified according to the cylinder arrangement (inline, V-type, radial, and opposed) or according to the method of cooling (liquid cooled or air cooled). Actually, all piston engines…

  • Chapter 14: Aircraft Fuel Systems › Types of Aviation Fuel › Reciprocating Engine Fuel—AVGAS

    fuel specified by the manufacturer. Mixing fuels is not permitted. There are two basic types of fuel discussed in this section: reciprocating-engine fuel (also known as gasoline or AVGAS) and turbine-engine fuel (also known as jet fuel ... Engine Fuel—AVGAS Reciprocating engines burn gasoline, also known as AVGAS. It is specially formulated for use in aircraft engines. Combustion releases energy in the fuel, which is converted into the mechanical motion of the engine. AVGAS of any variety…

  • Chapter 5: Engine Starting Systems › Reciprocating Engine Starting Systems › Direct Cranking Electric Starter

    Direct Cranking Electric Starter The most widely used starting system on all types of reciprocating engines utilizes the direct cranking electric starter. This type of starter provides instant and continual cranking when energized. The direct cranking electric starter consists basically…
