What types of bearings are generally found on reciprocating engines? Plain, roller, and ball bearings.
Are the connecting rods used in each cylinder of a radial engine the same? No. Radial engines use master and articulating rod assemblies.

What purpose do oil control rings serve? They regulate the thickness of the oil film on the cylinder walls.
What is used to help prevent valve surge or floating in an aircraft engine? Two or more springs are used on each valve.
On engines equipped with hydraulic valve lifters, what should the running tolerance be? Zero
What is the purpose of valve overlap? It allows better volumetric efficiency and lowers cylinder operating temperatures.
