VISCOSITY INDEX (VI) Explanation

When a person is cold, his natural reaction is to hold his arms

close to his body to retain warmth. Now imagine a crowd of cold

people, arms drawn in, moving past one another in a congested

hallway. Sure there is some congestion, but the people can still

move freely.

Now imagine the opposite. When a person is hot, he tends to

sprawl out. Picture a person holding his arms straight out from his

sides. It would be much more difficult to navigate a congested

hallway full of hot people, arms extended. Consider in this

example, the flow of people is related to the viscosity of the crowd.

PCV

14

Positive Crankcase Ventilation

A PCV Valve provides a oxygen to the

crankcase in order to release pressure built

up by the up and down movement of the

pistons.

This keeps the crankcase pressure at

atmospheric pressure so seals don’t blow

out from excess built up pressure.
