Understanding Engines

One of the three basic things an engine needs to run is:

• Fuel

• Electricity

• Lubricant

• Coolant

The air that an engine needs to run comes from:

• the fuel tank

• the exhaust system

• the atmosphere

• the cooling system

The gasoline or fuel that an engine needs to run comes from:

• a gas station

• a grocery store

• a pharmacy

• a library

The spark that an engine needs to run comes from:

• the battery

• the alternator

• the spark plug

• the fuel injector

• gasoline

• diesel

• water

• electricity

The fuel burning process in an engine is known as:

• Combustion

• Photosynthesis

• Evaporation

• Condensation

Fill in the blank: During the exhaust phase, the burnt gases are pushed out through the _______.

• exhaust valve

• intake valve

• spark plug

• piston

Which type of engine has simpler and consolidated mechanical processes?

• 2-stroke engine

• 4-stroke engine

• Both have the same complexity

• Neither has mechanical processes

What are the 4 "strokes" of a 4-stroke engine?

• Intake, compression, power, exhaust

• Intake, compression, exhaust, diesel

• Internal, Combustion, Exhaust, Gas
