The document compares internal combustion engines and electric engines. It provides a brief history of both, explaining how they work, and discusses their environmental impacts, costs, advantages, and disadvantages. The internal combustion engine relies on gasoline to power a vehicle, while the electric engine uses electricity stored in batteries to power an electric motor. While electric vehicles produce no direct emissions, combustion vehicles are more reliable with faster refueling and greater range per fill-up/charge.

1. IC engine Electric engine
engine using an on-board
• An engine is motor rechargeable energy storage
which converts system
chemical energy into a fueled power source for
mechanical energy vehicle propulsion.

2. History
• Otto Cycle: Dr. Nicolaus Otto -1876

3. History of the E.E
1800-
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“

4. fuel mixture is ignited by spark
Piston pushes out the
burnt gases to the
atmosphere
compress air fuel mixture
inside the cylinder &
compression takes suction stroke piston starts at
Top Dead Center of the cylinder
and moves to the Bottom

5. 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

6. Main idea
The internal combustion engine is
more reliable then the electric
engine…

7. Supportive claims!!!
Environmental burden- combustion vehicle
*Direct effect-
Smog, dirty air ,acid rain, health
problems
*Responsible for 20% of greenhouse gas
emissions

8. 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

9. Price and maintenance
Combustion vehicle Electric vehicle
Electricity is 0.5204
gas is 7.50 you are per kwh
between ages of 20- A 20-34 year old
34 year old drives drives 20000 km a
20000 km a year year
You driving a
Toyota corolla You driving a tesla
model s with 40
kwh battery

10. Combustion engine car
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

11. 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

12. Advantages and disadvantages

13. Advantages –combustion engine
Last longer in terms of miles
Distance traveled is more then the electric
Fast refueling
Safer then the electric

14. Advantages –Electric car
Require less maintenance
The engine is quieter
Electric cars are very easy to assemble
Recapturing waste energy

15. 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.

16. Disadvantages= Electric cars
Silence leads to accidents
Less driving range
Limited Service Facilities
Long time to recharge car batteries
Battery cost

17. Conclusion
Good idea but lack of means
Said to be 100% safer and greener
Really expensive
