Does Oil Pump Have Any Impact On Fuel Efficiency

Oil Pump Is located between the sump and oil filter

or else Below the engine Block

Types Of Oil

Pump

The Gear Type Oil Pump

Common form of Oil Pump

Consist 2 machinery gear

Rotate inside the close fitted housing

The Work Process Of gear type oil Pump….

Sends to the other parts of engine

Does Blocked Oil Flow Affect the engine ??

If the oil Flow blocked

If the engine oil is very

thick

Increase in pressure build up

Damage the Pump

How to solve the Problem ..???

A new oil-pressure relief Valve was fitted to eliminate these consequences

The Rotor Oil Pump

A rotor

An outer ring

Consist of pressure relief valve to eliminate

problems

The work process of Rotor Oil

Pump

Internal rotor

4 inner lobos

5 outer lobos

External rotor

Components of Eccentric Rotor

Oil Pump

The work Process

Oil drawn towards the

lobos

Lobos decrease the extra

pressure build up

The pressured oil sent to the engine parts

The Rotary-Plunger Oil Pump

Components A warm gear that rotate the plunger

The Work process

Rotary plunger

produces the pumping

action

Oil sent to the

engine

Limitation

Not appropriate for dry-sump

lubrication system

Oil will drain back to the system after

engine stopped

Prevents oil surge during fast

driving in race cars

Benefits

Produces extremely high pressure for oil

Components 2 oil pumps only

The work Process

1st pump sends the

oil to lubrication

system

2nd pump returns the un-used oil to the tank
