I call this blog a Scrambled Erratum! The description goes like this - "Aggregate of individuals
are left in confused state as even the smallest subatomic matter in their respective brains make
them scratch their heads by self or mechanical/electronic means, intentionally/unintentionally
deviating from what is correct, right or true."

THE END OF MECHANICAL ERA IN AUTOMOBILE INDUSTRY

" Switching ourselves from fossil fuel era to hydrogen fuel era will be having technological hurdles, the difficulty of creating a new energy infrastructure will be money swallowing and mind boggling, but could provide health, environmental, climatic and economic benefits and reduce the reliance on diminishing oil supplies and to establish a perfect platform ".

Does vehicles conversion from gasoline to diesel advisable even with advanced emissions and particle control technologies?

This would actually increase photochemical smog. The reason is that even advanced diesel vehicles may emit more oxides of nitrogen than do gasoline-powered vehicles, and these oxides spur ozone production.

Companies have invested hundreds of millions of dollars in fuel cell research with the ultimate goal of removing the auto from the environmental equation, because we believe the automobile leads the way to the hydrogen economy and a truly sustainable future.
HYDROGEN AS FUEL
A combination of electricity and internal combustion of gasoline, as in hybrid vehicles; hydrogen generated from wind electrolysis; hydrogen generated from natural gas; and hydrogen generated from coal gasification are the various forms of generation of hydrogen fuel.

While the production of carbon dioxide, a greenhouse gas, is undesirable, the process produces about 55 percent less carbon dioxide than the internal combustion.

ADVANCEMENT IN BATTERY STORAGE

Eliica Battery Electric Car with 370 km/h top speed and 200 km range…

Advances in lithium based battery technology, in large part driven by the consumer electronics industry, allow full sized, highway capable electric vehicles to be propelled as far on a single charge as conventional cars go on a single tank of gasoline. Lithium batteries have been made safe, can be recharged in minutes instead of hours, and now last longer than the typical vehicle.

Another improvement was to decouple the electric motor from the battery through electronic control while employing ultra-capacitors to buffer large but short power demands and recuperable braking energy.
FAST FORWARD
Innovators and dealmakers descend to soak up the hottest technologies that will blow minds, break barriers and fly off shelves in the years to come. By the implication of Robotics, Biometrics, Voice recognition devices, Audio networking solutions, Disposable technology, Nanotechnologies, Flexible computing devices and GPS etc will take automobile industry to the next dimension.
a deafening roaR

* As the fuel cell technology and usage of batteries has emerged with a roar, engines will be replaced in near future completely…

* Implication of fuel injection system in bikes has already ruled out the carburetors life…

* Robots have already overtaken the large part of assembling & manufacturing section long time ago…

* Steering systems will get replaced by joysticks/joy pad/remote control…etc

What's new now is that inexpensive semiconductors are available to provide the extraordinarily precise control of very large amounts of electric power, at very low cost, in very compact controllers.


The side stick, being tested by Mercedes-Benz, is part of a fully computer-controlled car handling system .

The transformation is already well under way in the car's peripheral systems. The belts and pulleys that drive water and oil pumps, and radiator cooling fans, are giving way to electric motors. The best brakes are already electro hydraulic, all electric brakes will follow. With electronic throttles, the gas pedal sends electrical instructions to a microprocessor that controls the fuel injection system electronically. Passive, reactive, energy dissipating springs and shock absorbers are being displaced by an active array of powerful linear motors that move wheels vertically as needed to maintain traction beneath and a smooth ride above.

And electric actuators will displace the steel camshaft on every valued engine. Put each valve under precise, direct, digital-electric control, actuated independently by its own compact electric motor open and close each valve as dictated by current engine temperature, terrain, load, and countless other variables and, in effect, you continuously retune the engine for peak performance. Belts, shafts, and chains melt away. Everything shrinks, everything gets lighter, and every aspect of performance improves dramatically.

Cheap in the Gearbox

This will set the stage for the last big step the one already taken in monster trucks. Silicon and electric power will knock out the entire gearbox, driveshaft, differential, and related hardware, electric drives powers the motors that turn the wheels. Power chips now make it possible to build high power motors the size of a coffee can, and prices are dropping fast. When such motors finally begin driving the wheels, the entire output of the engine will have to be converted immediately into electricity before it is distributed, used, or stored throughout the car. It will take heavy duty wiring and substantial silicon drives and electric motors to propel a hybrid electric sport utility vehicle down a highway at 70 mph but they'll be far smaller than the steel structures in today's power train. Cars will shed many hundreds of pounds, and every key aspect of performance will improve considerably.
CONCLUSION:
The era of Draftsmen came to an end by the introduction of software’s like AUTO CADD, PRO-E, ANSYS, CATIA, SOLIDEDGE etc…

In the same way there will be no need of people who are specialized in engines, steering mechanisms, carburetors and other systems which is gonna be outta f no where… We are currently studying systems which are going to be outdated in near future…everything is gonna be ruled by pre programmed microchips… simply just as your PC… so what will we(the present generation of mechanical engineers) do by having such outdated shit in our syllabi...

So what will be the future of mechanical engineers in the automobile industry as mechanical era is getting converted into electronics era???

NOTE: I went through various websites for my analysis purpose on this topic. The points which i thought would add spice to this post were included in various parts of this post.

@ raghu

that was a good article. we are moving out of the gas or petrol n onto more efficient methods.

for instance in hydrogen fuel , only water is left as waste. but there is still a lot left over to engineer.

i know a automobile engineer who is desiogning a vehicle which can run equally fast in both water and land..

scope is always there, but as u pointed u, its little

@barbi

actually automobile engineer reads basically a lot about all kind f transportation system...but am not talking abt an automobile engineers future...

the mechanical era is getting converted into electronics era...so there will be no scope for mechanical engineers in automobile field...

In near future even the cylinders may get replaced by some other alternative means...

At this point of time, when people are adopting to ALTERNATE FUELS. So it is goin to be a great advancement in the field of transport technology, that everything wud be on ELECTRONICS. A nice piece of info and a very real fact. I think u are too fast than time, and i see a foreseer before me.....

Please note that the way the car is manufactured will still be mechanical.

@barbi
ya scope is very very little...but still designing line may hlp mech engineers a bit...

@yamunan
am i really faster than time??hmm...actually these are already been implemented and tested...but yet to get themselves established...ELECTORNICS is gonna rule the AUTOMOBILE ERA but still with fewer mechanical components...

@Sheks
car will remain mechanical...but with fewer components like axle, frame, chassis etc...only the manufacturers will attain profit and earn more nd more money...but worker's will be paid low unlike now...

Dai pappu, your post tested my patience a lot. Basically Im not in for technical stuffs and your post was getting a little too technical for me! :d The future of mechanical engineers in automobile industry sure does hang in the balance as the mechanical era is slowly but steadily transforming into the electronic era.

@ganesh prabhu
Mind u it is not slowly tranforming da...it is transforming at rapid pace...these thing w'll come to market in a year r even b4 that...

@dude
aeroplane-->aeronautical engg
trains -->locomotive engg

plez read the topic once again...

bikes & scooters...
there is already a bike by name "EGO" in market, It is 160cc scooter which runs without engine but motor...
In bikes the carburetor is already been eliminated by the introduction of fuel injection technology...even battery bikes are found in testing grounds...

In near future even the bikes may run in motors or even hydrogen fuel may be used...

so mechanical era is shrinking in automobile field.
