Hybrid vehicles

Update: Hybrid vehicles are getting increasingly popular these days. When I added this post 6 years ago I saw only one hybrid car, that was Toyota Prius. Now hybrid cars are not only affordable they are also getting better and better. Recently Maruti Ciaz launched their hybrid version. With the coming of Tesla, car manufacturers are increasingly investing in Electric cars as well. Without a doubt it will be electric and hybrid cars that rule the road in a few years.

Hybrid cars definitely make a good topic for a mechanical engineering seminar. You can also try it for your project as well.

The dictionary defines hybrid as something of mixed origin. A hybrid vehicle is one that combines a smaller than normal internal combustion gasoline engine with an electric motor. An engine that combines two or more sources of power is called a hybrid engine.

Typical features in a hybrid include the following:
• Produces much less pollution than standard gasoline cars
• Usually constructed of ultra light weight materials like carbon fiber or aluminum to overcome the power gap.
• Generally designed to be more aerodynamic than most cars, allowing them to “slice” through the air instead of pushing it out of the way
• A process called regenerative braking is employed to store the kinetic energy generated by brake use in the batteries, which in turn will power the electric motor.
Power usage:
• Electric power is used at starts and stops, low speeds (generally below 25 km/hr)
• Gasoline engine comes to play at cruising or highway speeds

There are two types of gasoline-electric hybrids:
• Parallel hybrid:
Gasoline engine and electric motor work together to move the car forward
• Series hybrid
Gasoline engine either directly powers an electric motor that powers the vehicle, or changes batteries.

Hybrids achieve improved efficiency using several approaches:
• Employ regenerative braking to recover energy and downsize or right size the engine or primary power source.
• Control the engine or primary power source to operate more efficiently and/or work more often in a more efficient range.

HI SIR this is shiva i would like to know more about this topic because i also having same and similar thought but i apply this for 2wheeler you are applied for 4wheeler a small change so i need more information will u please send your reply to my mail my mail id is shiva36307@gmail.com thanking you sir

hello sir i am a student of b-tech third year in mechanical branch i want to make an innovative project on automobile . i can make it on any system of automobile the only thing is that i am not able to find aright and appropriate idea. i can make an investment of about 20k to 25k.so pls suggest me some4thing.
thank you

Hello Sir,this is Hrishikesh,a student of mech.engg.diploma final year.Resp. sir I want to make an innovative project.I request you to send me new Ideas.I can able to make investmena upto 10000 thousands to 15000.
Thank you.

Sir,
I want to more information on Hybrid Vehicles. I want the actual mechanism, how it happens and all that.
Plz mail me the details regarding this.
Thanks.

Hello sir…….. plz give me whole detail about this projet……
i have a question that……….. can we hybrid of petrol and CNG ??????

sir this is an awesome topic, plz can u give me more info about this as i want to give my technical seminar on this topic.
