4.Anti-Corrosion and Lubrication
3.Lubrication and Cooling
With regard to oil quantity, temperature and pressure, which statement do you think is most accurate?
Select one:
1.A low oil quantity can lead to higher oil temperatures and lower oil pressure
2.A high oil quantity can lead to lower oil temperatures and higher oil pressure
3.A low oil quantity can lead to lower oil temperatures and lower oil pressure
4.A high oil quantity can lead to higher oil temperatures and lower oil pressure
1.A low oil quantity can lead to higher oil temperatures and lower oil pressure
What is the purpose of the oil tank
Select one:
1.It holds a supply of cooled clean oil ready for use.
2.It holds the oil until the engine is running, then oil is stored in the sump.
3.It is there in case the sump becomes too full and then it will take the excess.
4.It holds the oil while it is waiting to be cooled and cleaned.
1.It holds a supply of cooled clean oil ready for use.
Regarding the pumps in a dry sump system
Select one:
1.The Scavenge pump is a lower flow pump than the Pressure Pump to ensure the Sump stays empty.
2.The Pressure pump is a lower flow pump than the Scavenge Pump to ensure the Sump stays full.
3.The Pressure pump is a higher flow pump than the Scavenge Pump to ensure the Sump stays empty.
4.The Pressure pump is a lower flow pump than the Scavenge Pump to ensure the Sump stays empty.
4.The Pressure pump is a lower flow pump than the Scavenge Pump to ensure the Sump stays empty.
