2.5 Reciprocating Engines
2.5.1
2.5.2 Crankshafts
2.5.2.1
2.5.3 Connecting Rods
2.5.3.1 The connecting rod is the link that transmits forces between the piston and the crankshaft.
2.5.4 Pistons
2.5.4.1 The piston of a reciprocating engine is a cylindrical member which moves back and forth within a steel cylinder.
2.5.4.1.1 Piston Rings
2.5.4.1.1.1 The piston rings prevent leakage of gas pressure from the combustion chamber and reduce to a minimum the seepage of oil into the combustion chamber.
2.5.5 Cylinders
2.5.5.1 The portion of the engine in which the power is developed is called the cylinder.
2.5.5.1.1 Firing Order
2.5.5.1.1.1 The firing order of an engine is the sequence in which the power event occurs in the different cylinders.
2.5.6 Valves
2.5.6.1
2.5.7 Bearings
2.5.7.1 A bearing is any surface which supports, or is supported by, another surface.
