A reciprocating engine is found to have excessive oil consumption without evidence of any oil leaks. What is the most likely cause? - ANS The piston rings are worn or broken What are the functions of lubricating oil in reciprocating engines? - ANS To reduce friction between moving parts and remove heat Name two important characteristics of aircraft engine oil - ANS The oil must be light enough to circulate freely yet heavy enough to provide the proper oil film...

What is the purpose of dynamic dampers on crankshafts? - ANS They reduce engine vibration. What types of bearings are generally found in reciprocating engines? - ANS Plain, ball and roller bearings. Are the connecting rods used in each cylinder of a radial engine the same? Explain. - ANS No. Radial engines use master and articulating rod assemblies. Name the different types of piston rings. - ANS Oil control, compression, and oil scraper. Where...

How are conventional reciprocating engines classified? - ANS - They are classified according to cylinder arrangement with respect to the crankshaft (in-line, V-type, radial and opposed), or according to method of cooling {liquid cooled or air-cooled). What are the different types of piston rings? - ANS - Compression rings, oil control rings, and scraper rings What is the purpose of the oil control rings? - ANS - They are used to control the thickness of the oi...
