Introduction to conventional vehicles  Hydrocarbon-fueled ICEs are the power plant of choice for vehicles in the power range from 5 Watts to 100,000,000 Watts, and have been for 100 years

Working of ICE

• Definition of an ICE: a heat engine in which the heat source is a combustible mixture that also serves as the working fluid • The working fluid in turn is used either to • Produce shaft work by pushing on a piston or turbine blade that in turn drives a rotating shaft or • Creates a high-momentum fluid that is used directly for propulsive force

3

What is / is not an ICE? IS • Gasoline-fueled reciprocating piston engine • Diesel-fueled reciprocating piston engine • Gas turbine • Rocket

IS NOT • Steam power plant • Solar power plant • Nuclear power plant

ICE family tree Internal Combustion Engines Steady Gas Turbine Uses compressor and turbine, not piston-cylinder

Non-steady Premixed-charge Fuel and air are mixed before/during compression Usually ignited with spark after compression

Turboshaft All shaft work to drive propeller, generator, rotor (helicopter)

Two-stroke One complete thermodynamic cycle per revolution of engine

Turbofan Part shaft, part jet "ducted propeller"

Four-stroke One complete thermodynamic cycle per two revolutions of engine

Turbojet All jet except for work needed to drive compressor Ramjet No compressor or turbine Use high Mach no. ram effect for compression Rocket Carries both fuel and oxidant Jet power only, no shaft work

Non-premixed charge Only air is compressed, fuel is injected into cylinder after compression Two-stroke One complete thermodynamic cycle per revolution of engine Four-stroke One complete thermodynamic cycle per two revolutions of engine

Solid fuel Fuel and oxidant are premixed and put inside combustion chamber Liquid fuel Fuel and oxidant are initially separated and pumped into combustion chamber

Why EV?

Common Electric Vehicle Myths MYTH: Plug-in electric vehicles can only support short trips, not daily commutes.

MYTH: Plug-in electric vehicles aren’t “clean.” Instead of burning gas, they run off of dirty power plants.

FACT: The average is 40 miles or less, and most full battery electric vehicles are targeting close to 100-mile range on a full charge, and with plug-in hybrid electric vehicles, you can go even further up to 300 miles or more.

FACT: Even when emissions from power plants are taken into consideration, electric vehicles contribute significantly less green house gases than traditional cars.

MYTH: Electric vehicles will make your energy bill go way up.

MYTH: Electric vehicles are far more expensive than the average car.

FACT: Slightly higher electric bills are offset by savings at the gas pump. This would be like filling up for a few cents per mile, compared to the average 14 cents for a traditional car.

FACT: Federal tax incentives are available, up to $7,500 as well as possible state and local incentives. Compared to gas-powered cars, you will save on fuel, maintenance and repair costs.
