Transcript of Hybrid Cars

Hybrid Cars By Casey Haag and Eddie Billings How does a hybrid car work? Where will we be in 10 years? The Environment Batteries Engine Types Power What is a hybrid car? Progress The first mainstream hybrid car The origin of hybrid cars A hybrid vehicle is a vehicle that uses two or more distinct power sources to move itself. The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors IN 1999 Honda released the two-door Insight, the first hybrid car to hit the mass market in the United States. The Insight won numerous awards and received EPA mileage ratings of 61 mpg city and 70 mpg highway. The Toyota Prius II won 2004 Car of the Year Awards from Motor Trend Magazine and the North American Auto Show. Toyota was surprised by the demand and pumped up its production from 36,000 to 47,000 for the U.S. market. Interested buyers waited up to six months to purchase the 2004 Prius. Toyota Motor Sales U.S.A. President Jim Press called it "the hottest car we've ever had." Power sources for hybrid vehicles include:
On-board or out-board rechargeable energy storage system (RESS), Coal, wood or other solid combustibles, Electricity, Electromagnetic fields, Radio waves, Compressed or liquefied natural gas, Human powered e.g. pedaling or rowing, Hydrogen, Petrol or Diesel fuel, Solar, and Wind. Hybrid Electric Petroleum Vehicles-uses internal combustion engines (generally gasoline or Diesel engines, powered by a variety of fuels) and electric batteries to power the vehicle.
Continuously outboard recharged electric vehicle (COREV)-can be recharged while the user drives
Hybrid Fuel-can switch between an on board diesel engine and overhead electrical power depending on conditions.
Fluid Powered Hybrid-Hydraulic and pneumatic hybrid vehicles use an engine to charge a pressure accumulator to drive the wheels via hydraulic or pneumatic (i.e. compressed air) drive units! The hybrid is a compromise. It attempts to significantly increase the mileage and reduce the emissions of a gas-powered car while overcoming the shortcomings of an electric car The batteries in a hybrid car are the energy storage device for the electric motor. Unlike the gasoline in the fuel tank, which can only power the gasoline engine, the electric motor on a hybrid car can put energy into the batteries as well as draw energy from them. The environmental advantages of the both electric and hybrid car should be quite obvious to everybody, increased health for both people and nature. It is long since proved that the use of oil products releases more pollution into the air than the nature can take care of, increasing risks of both cancer and lung diseases. Electric motor - The electric motor on a hybrid car is very sophisticated. Advanced electronics allow it to act as a motor as well as a generator. For example, when it needs to, it can draw energy from the batteries to accelerate the car. But acting as a generator, it can slow the car down and return energy to the batteries. The pollution produced by cars might also get carried into the atmosphere where it transforms into acidic rain, one of the worst problems for nature and even planted crops. So by using hybrid and electric cars humanity not only does the nature a favour but also does our selves a favour.
