Ams 271 Unit 3 Question and answers
correctly solved
Viscosity - correct answer ✔Oil's resistance to flow
Cloud point - correct answer ✔The temperature at which paraffin wax &
other solids notmally held in a solutionof oil begin to solidify & separate into
tiny crystals. At this temperature, the oil begins to lose clarity and appears
cloudy or hazy
Flash point - correct answer ✔Temperature at which oil begins to emit
ignitable vapors
Fire point - correct answer ✔Emits enough vapor to support a flame
Pressure lubrication - correct answer ✔primary type of lubrication used in
reciprocating engines
Spray Lubrication - correct answer ✔Uses the same pressurized oil from the
pressure system and the oil is sprayed onto components through a nozzle
Splash Lubrication - correct answer ✔Movement of internal components
splash oil all around the crankcase
Wet sump system - correct answer ✔Oil is stored in the crankcase and is
distributed by a pump
Dry sump system - correct answer ✔Oil is stored in a reservoir seperate from
the engine
