PROJECT DEFINITION
To Explain The Working And Construction Of A Hybrid Vehicle.
To Examine The Efficiency, Improvements And Advantages Of Hybrid Vehicle Over A Solo Engine Traditional Engine.
To Present The Technologies Available And Possible Improvements.
INTRODUCTION
A Hybrid Combines Two Methods For The Propulsion Of A Vehicle.
Possible Combinations Include Diesel/Electric, Gasoline/Fly Wheel, And Fuel Cell/Battery.
Typically One Energy Source Is Storage And The Other Is Conversion Of A Fuel To Energy.
PRESENTATION OVERVIEW
Need of Hybrid Vehicles
Types Of Hybrids
Various Hybrid Vehicle Types
Construction Of Hybrid Vehicles
Working Of Hybrid Vehicles
Emissions And Environmental Impact
Precautions To Operate A Hybrid Vehicle
Latest Developments
Conclusion
NEED FOR HYBRID VEHICLES
•Regenerative braking .
•Fuel efficiency is greatly increased (twice).
•Emissions are greatly decreased.
•Dependency on fossils fuels can be decreased.
•Hybrids can be run on alternative fuels as well.
•New materials can be implemented.
REGENERATIVE BRAKING
• A regenerative brake is an energy recovery mechanism
• Converts Kinetic energy into Electrical form.
• While braking, it absorbs 80% of kinetic energy.
CONSTRUCTION OF HYBRID VEHICLE
Working
• Basic Components.
• Acceleration.
• City driving.
• Highway Driving
• Driving up a
gradient.
TYPES OF HYBRID VEHICLES
SERIES HYBRID PARALLEL HYBRID
1)Series Hybrids:
Cars which has only the electric motor which is directly connected to the transmission.
In a series hybrid, the gasoline engine is only used to charge the batteries that are used to power the electric motor.
2)Parallel hybrids
To turn the transmission they use either its electric motor or gasoline engine. Because of this, both the electric motor and the gasoline engines are connected directly to the transmission of the car.
Advantages of Hybrid Vehicles Lower emissions and better mileage.
Hybrid cars use no energy during idle state, they turn off anduse less than petrol engines at low speeds.
At lower speeds i.e. in traffic no smog is emitted maintainingits sustainable advantage.
Hybrid cars offers greater mileage than other cars.
Noise pollution and emission of CO2 are considerably reduced.
Hybrids are reliable and comfortable.
Hybrids are much cleaner cars than normal vehicles
Due to the Regenerative Braking technology, the batteriesneed not be charged by an external source.
Hybrids help reduce the dependency on fossil fuels whichdirectly affects fuel prices
Positive Environmental Impact
• The two types of hybrids:
• Electric hybrids: Electric hybrids use the electric motor as their alternative energy source.
• Hydrogen hybrids: Hydrogen hybrids extract the element from water and add the hydrogen to the fuel-air mixture of the vehicle.
Drawbacks of Hybrid Vehicles Hybrid cars are more expensive than normal cars.
Hybrid cars are much more complex in construction andworking than the IC engine cars.
Hybrid cars offer larger repair bills.
Batteries are not yet much advanced so as the car could run fora larger distance on batteries itself.
More weight due to battery packs.
In the event of an unfortunate accident, there is a risk ofexposure to high voltage wires.
Complicated Architecture.
Not suitable for long distance journey.
Some batteries fail deliver in cold weather.
Spare parts maybe hard to find and may be costly.
Negative Environmental Impact
• Hybrid electric vehicles (HEVs) are praised as being fuel efficient, and good for the environment. Most HEV owners will agree about the gas mileage: On average, HEVs get twice as many miles per gallon as conventional counterparts, data show. But the environmental impact of HEVs is harder to quantify, particularly since they are still relatively new to the automobile market.
Emissions
• One of the major negative effects of automobiles on the environment is smog-producing gases. Smog is particularly evident in large metropolitan areas, where many thousands of cars are concentrated. The gases that make up smog include nitrogen oxides, hydrocarbons, and other volatile organic compounds. Hybrid cars produce fewer gas emissions than conventional cars, but not as much less as you might think. Generally, the larger the car, the greater the difference in emissions between the hybrid and conventional versions. On average, compact hybrid cars produce 10% fewer smog-producing emissions than their conventional counterparts. Hybrid models of mid-size cars, mid-size sport-utility vehicles, and full-size SUVs reduce smog-producing gas emissions by 15%, 19% and 21%, respectively, over their conventional counterparts.
