Oil pumped from the sump through filter element, then pushed through oil galleries, so all of oil travelling in engine is known as:

• Full flow lubrication

• Bypass lubrication

• Hydrodynamic lubrication

• Boundary lubrication

Pump only feeds some oil through engine, the rest is forced through fine filter and returned to sump - oil in sump is cleaner at all times. is known as?

• Bypass lubrication

• Full flow lubrication

• Boundary lubrication

• Hydrodynamic lubrication

What type of oil pump is pictured?

• Crescent type

• Half moon type

• Gear type

• Eccentric type

What lubrication system is shown in picture?

• Full flow

• Bypass

• Boundary

• Hydrodynamic

What happens when a filter gets blocked?

• a relief valve opens allowing oil to bypass filter

• The engine will not start

• The oil bypasses pump

• relief valve in pump dumps excess pressure back into sump
