The Internal Combustion Engine
• In 1876 Nicholas Otto invented the four stroke internal combustion engine. He called it the Otto Cycle Engine.

How Does It Work• A gas-fuel
mixture is ignited by a spark plug inside the chamber. The explosion pushes the piston which turns the crank shaft.

The Ignition System• The first
ignition system was invented in 1911 by GM engineers Clyde Coleman and Charles Kettering.

How Does It Work
• The battery provides the initial power source for ignition. Once the car is started the alternator takes over.

Transmission• Automatic transmissions are more
common in cars. But, some people still appreciate manual transmissions.

Cooling/Exhaust Systems• Cooling and Exhaust Systems in
vehicles basically work with a pump and a series of intake and outtake lines.

Cooling, Heating Systems• Coolant is pumped through the engine through
a series of hoses. This keeps the engine from overheating.

Exhaust Systems• Hazardous fumes are pushed out of the piston
chamber by the piston and expelled out the tailpipe through a series of pipes and chambers.

Computers In Transportation
• Computers exist in most modern cars. In the form of GPS Systems and diagnostic controls.

Diagnostics• Sensors send
messages to the central computer. The computer relays the message to the driver through a display panel.

Modes Of Transportation
• The Department Of Transportation controls every mode of transportation from ground, water, sea and air travel.

Mass Transit Systems
• Mass Transit Systems are public forms of transportation that carry large groups of people at a time.

Transportation Impacts
• Transportation technology has severe positive and negative impacts. Our economy depends on transportation yet it creates a lot of pollution.
