_______ go through mountains or under waterways. Freeways, Highways Bridges, Tunnels Asphalt, Back Roads

Pg. 451


The Chunnel: Although there are far longer tunnels (the champion road tunnel is in Norway), this 31mile underground highway fulfilled a dream of Napoleon’s by linking Britain and France. Digging beneath the English Channel was considered a more significant feat than tunneling through earth (i.e., the famed 40mile Mont Blanc tunnel). \Whether the French and the British are happy being linked is another question.

Parallel Hybrid Drive System

Specialty Training

• Hybrid Technology

Specialty Training

• Hybrid Technology – Plugin Hybrid

Specialty Training There are two basic HEV configurations: The serieshybrid system uses a small

fuelburning engine to drive a generator for electricity—sent to one or more

electric motors which drive the wheels. When the traction storage batteries

need recharging, the engine starts up to run the generator for recharging.

Some vehicles can be intentionally operated in an all electric (zero emissions) mode around town.

In the parallelhybrid system there are two power paths. Either the fuel burning (heat) engine, the electric

propulsion system, or both, power the wheels. For longer trips, the heat engine provides primary power to the vehicle with the electric motor assisting under

peak loads.
