Transcript of Evolution of automobiles

The great inventions that brought Car, to the Common are

Birth of Pneumatic Tyre by Dr.Dunlop.

Invention of the automobile itself, by Benz.

Invention of Assembly Line, by Henry Ford, for Model T.

Thermal Cracking Crude Oil, by William Burton.

Development of other technologies like CRDI, VTEC.

It was a birthday gift, to his son by Dr.Dunlop

But that Bicycle made his son to feel the hardness of the countryside road of the Ireland. Observing this, he wanted to give his son a smooth ride and made a history.

Dr.Dunlop, was a surgeon, he used rubber sheets and sewed in to tubes with help of his surgeon’s skill.

He made it air tight by apply glue and liquid rubber.

He removed that old hard rubber tyre from the rim and glued his new rubber sheet tube.

Then he wrapped strips of canvas round the tube.

And the birth of pneumatic tyres took place, which made the future rides smooth and comfortable.

It was time when world is travelling on foot or by horse-carriage.

Karl Benz, a German engineer, was determined to build the first horse less carriage, what he called “patent motor-wagen”. He worked on it from the age of 15 and for 20years.

He made a prototype with 1 cylinder and a single forward gear,958cc and 0.8hp.

Though Karl Benz made a prototype, but he was not allowed by the officials that a horse less carriage is against nature.

Benz, was afraid and had no idea how make his invention public and commercialize.

Bertha Benz , Karl Benz’s wife took over. She, confident on her husband’s invention, without

permission of her husband and officials, made a trip to her sister’s house in Pforzheim 106kms away, marked as Bertha Benz Memorial Route.

This was the first ever long distance travel on motor-wagen. This made the Benz Motor-Wagen , a succcess and a first patented and commercially sold automobile. This eventually, established

Benz & Cie company.

Though the car is in existence for the decades, it was in 1908, The Car made available to Middle class Americans by Mr.Henry Ford, by his genius idea of Assembly Line, which made production of cars more cheap and fast.

Model-T is the first car manufactured by using assembly lines and the first affordable car.

From 1908 to 1927 it was revolution, more half worlds’ cars were Fords. 15 million Model-Ts were sold, only Volkswagen Beetle surpassed in 1972.

Henry Ford with his Model-T

Ford once, went to a pork shop where he saw a disassembly line, where pigs passed from one person to another, each person doing particular job.

This made Ford, to get the idea of assembly line, where needs proficiency in only one type of job, and job can be done more quickly.

Assembly Line, born and brought down the production time and cost drastically.

Thus bringing car more close to common middle class people.

Thermal Cracking is a process of breaking long hydrocarbon chains of crude oil into saturated hydrocarbon chains which will by-products like gasoline, kerosene etc.

William Burton was manager at Standard Oil Co. at Indiana state.

Realizing that future lies in gasoline, he desperately worked on producing gasoline in a cheaper way.

In 1911, at Standard Oil Co. he was ready to risk his life, to practically test his theoretical work.

He along with his men is ready to Thermally Crack the Crude Oil.

In thermal cracking, the crude oil is heated upto 700°C and 700kPa, by which the long hydrocarbons break into small chains.

But then, without any safety measures and crude oil at high temp and pressure which is highly prone to blasting, all their lives were at risk.

Burton did not, turned back and continued the experiment and it was a success.

This made gasoline cheaply available, to be used in IC engines.

World’s future fuel was created cheaply.

Thus these, major inventions made and brought the Automobile, to the common man of this World.

There many other developments took place in the field , which made cars to become more common mode of transport.

Common Rail Injection systems were developed first in Switzerland and Japan.

These were very efficient and made cars more smooth, fuel efficient than their older cam driven systems. Alfa Romeo 1977 model and Benz C-class used this technology first.

Today almost all the automobile manufacturers use this technology with different names.

Honda’s engineer Ikou, has developed VTEC(Variable Time and Lift Electronic Control) technology, by which volumetric efficiency of the engines increased.

There will be two cam lobe profiles for high and low rpm of the engine, controlled by ECU, this makes fuel injection more efficient.

Today all cars of Honda use i-VTEC engines, making them performance and efficient engines.
