1. SYSTEM DESCRIPTION

1) Overview

The lubrication system supplies oil to each lubrication section to prevent friction and wear and to remove

heat from the friction part. As the engine runs, frictional heat is generated on each lubrication section. If

this condition persists, the bearing can be burned and stuck.

In other words, it creates an oil film on each sliding surface to convert solid friction to liquid friction in

order to minimize wear and prevent temperature increasing on the friction part.

For the D20DTF engine with no oil pressure switch, the engine ECU receives the low engine oil level

signal from the oil level sensor and communicates with the instrument cluster through the CAN

communication to turn on the warning lamp.

3. LUBRICATION

1)Anti-friction

The oil makes a thin film on the surface of sliding components to reduce the wear due to friction.

2)Cooling

The friction makes the heat on the components. The oil absorbs the heat and radiates it or cools it down.

3) Sealing

The piston ring on the piston seals the cylinder. The oil gets into the clearance in piston ring to secure

the sealing for compression pressure and combustion gas.

4) Anti-corrosion

The oil generates the thin film on the surface of components to prevent the material from contacting with

air, water and corrosive gas.

5) Cleaning

The oil transfers the residue of material due to friction, oxidized substance, and carbonized substance

while circulating in the engine by oil pump.
