2、BRIDHybrid Drive07 FORD ESCAPE HYBRIDHybrid DrivelA gasoline car produces a relatively large amount of pollutant and generally gets poor gas mileage.An electric car,however,produces almost no pollution,but it can only go 50 to 100 miles(80 to 161 km)between charges，and is very slow and inconvenient
3、to recharge.lA gasoline-electric car combines these two setups into one system that levers both gas power and electric power.lThe Mercedes-Benz M-Class HyPer-a hybrid concept vehicle 3/23Hybrid DriveThe Mercedes-Benz M-Class HyPer-a hybrid concept vehicle 4/23Hybrid DriveStructure of Hybrid Drive Ga
4、soline-electric hybrid cars contain the following parts:Gasoline engine-The hybrid car has a gasoline engine much like the one you will find on most cars.However,the engine on a hybrid is smaller and uses advanced technologies to reduce emissions and increase efficiency.Fuel tank-The fuel tank in a
5、hybrid is the energy storage device for the gasoline engine.Gasoline has a much higher energy density than batteries do.For example,it takes about 1,000 pounds of batteries to store as much energy as 1 gallon(7 pounds)of gasoline.Electric motor-The electric motor on a hybrid car is very sophisticate
6、d.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.5/23Hybrid Drive Generator-The generator is similar
7、to an electric motor,but it acts only to produce electrical power.It is used mostly on series hybrids.Batteries-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 hyb
8、rid car can put energy into the batteries as well as draw energy from them.Transmission-The transmission on a hybrid car performs the same basic function as the transmission on a conventional car 1.Some hybrids,like the Honda Insight,have conventional transmissions.Others,like the Toyota Prius,have
