IC engine

• An engine is motor which converts chemical energy into mechanical energy

Electric engine

engine using an on-board rechargeable energy storage system

a fueled power source for vehicle propulsion.

History• Otto Cycle: Dr. Nicolaus Otto -1876

History of the E.E1800- Alessandro Volta was known for the invention of the battery  1990s-

hybrid technology became successful when the Honda Insight & Toyota Prius became available

2007- Lexus offers a hybrid sport sedan the GS450h

"well in excess of 300hp“

suction stroke piston starts at Top Dead Center of the cylinder and moves to the Bottom

compress air fuel mixture inside the cylinder & compression takes

fuel mixture is ignited by spark

Piston pushes out the burnt gases to the atmosphere

How does it work?• *Use electricity and petrol fuel• *Energy comes from a power outlet via a

cord to the car• *Energy stored in a battery• *Energy powers the • electric motor

Main ideaThe internal combustion engine is more reliable then the electric engine…

Environmental burden- combustion vehicle

*Direct effect-

Smog, dirty air ,acid rain, health problems

*Responsible for 20% of greenhouse gas emissions

Supportive claims!!!

Environmental burden -electric vehicle•*Account fair share of pollution and environmental impacts

•* rely on power grid for energy source 54% of American power •Generated by coal

•*coal is single biggest polluter in the us cause toxic air

•*Environmental impact of batteries

• life cycle experiment 15% of an electric cars environmental burden comes from lithium ion batteries .

Mining raw materials Manufacture process Disposal of acids •

Combustion vehicle Electric vehicle

Price and maintenance

gas is 7.50 you are between ages of 20-34 year old drives 20000 km a year You driving a Toyota corolla

Electricity is 0.5204 per kwh A 20-34 year old drives 20000 km a year

You driving a tesla model s with 40 kwh battery

Toyota corolla- can hold 50 liters of fuel 1 liter is 12.7 km total is 635 km

With 20000 km annually . A person would have to fill up to 35 times

A person will spend more then 6000 on gasoline car a year

Combustion engine car

Electric engine car

1 kwh cost 2.8 , 40 kwh you can drive 256 km , it cost 112

Every 3 days you need to charge , 224 a week

52* 224 =11648

Advantages and disadvantages

Advantages –combustion engine

Last longer in terms of miles

Distance traveled is more then the electric

Fast refueling

Safer then the electric

Advantages –Electric car

Require less maintenance

The engine is quieter

Electric cars are very easy to assemble

Recapturing waste energy

Disadvantages – combustion engine cars

Air pollution

The supply of petrol is decreasing and we will one day run out of it

Because of the high demand and decreasing supply, the price of petrol is increasing.

Disadvantages= Electric carsSilence leads to accidents

Less driving range

Limited Service Facilities

Long time to recharge car batteries

Battery cost

Conclusion

Good idea but lack of means

Said to be 100% safer and greener

Really expensive
