Air induction

Air density is greater when ?

• Hot

• Wet

• cold

• dry

Which answer is not apart of the air intake induction

• Air restriction guage

• Air filter

• Air shut off device

• Exhaust manifold

The air induction serves several purposes, the main functions are:

• It cleans the air supply

• Allows more air pressure to the air brake system

• It provides air for combustion

Pressurized Intake air can be cooled by which method

• Radiator

• Thermo heat exchanger

• Inter-cooler

• Air to air cooler

A turbo charged engine will provide

• Greater volumetric heat

• Greater amount of fuel

• Greater amount of volumetric efficiency

• A cooler noise on the exhaust

Some off-road construction sites are extremely dusty, In these condition, what should be consider of air induction

• A larger filter

• A pre-cleaner filter

• Aftertreatment filter

• Water cooled filter

What is the purpose of a hose that is attached to the exhaust pipe and filter housing

• To warm up the intake

• To create Scavenging effect

• Increase boost pressure

• Lower emissions of the engine

Two main types of air cleaners assemblies maybe used to filter the air are

• Water bath

• Oil bath

• Ice bath

• Dry type element

A dry type filter will filter from?

• Outside to inside

• Inside to outside

• Dirt is heavier, it just falls into the canister

• All the answers are correct

The scale units of a air restriction gauge is ?

• Inches of water

• Newtons

• Inches of mercury

• PSI
