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.

Steering And Suspension Systems

Steering/SuspensionTroubleshooting steering and suspension on your car can be difficult. Click the link above for tips.

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.

Shipping• UPS provides

shipping service all across the country. There are many other shipping companies that carry goods to factoriess and businesses that drive our economy.

Transportation Impacts

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