Some compression rings - Study guides, Class notes & Summaries

Wet compression test If a piston ring is leaking, this type of test will indicate some compression. If a valve is burned, this type of test will make no difference and indicate the same readings Blue Smoke this means the engine is burning oil. Could be caused by worn piston rings White Exhaust Smoke caused by coolant leaking into one or more cylinders, such as when a head gasket goes bad Worn valve guides and vacuum readings this condition would cause the vacuum gauge ne...

What is the main advantage of a horizontally opposed engine over a radial engine for powering modern aircraft? - ANSWER-The horizontally opposed engine has a much smaller frontal area and is easier to streamline than a radial engine. How many throws are there in the crankshaft of a six-cylinder horizontally opposed engine? - ANSWER-six What kind of connecting rod arrangement is used in a radial engine? - ANSWER-A master rod connects the single throw of the crankshaft with a piston. All oth...

The tread of a tire is worn in the center and not on the outer shoulders. Technician A says this is caused by an improper wheel alignment angle. Technician B says this is caused by an over-inflated tire. Who is correct? B Technician A says that oil should be squirted into all of the cylinders before taking a compression test. Technician B says that if the compression greatly increases when some oil is squirted into the cylinders, it indicates defective or worn piston rings. Whic...

What is the purpose of dynamic dampers on crankshafts? - They reduce engine vibration. What types of bearings are generally found in reciprocating engines? - Plain, ball and roller bearings.
