internal combustion engine vs electric engine
TRANSCRIPT
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 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
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 –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
