Starting To Think

• Several Italians recorded designs for wind driven vehicles– The first was Guido da Vigevano in 1335.– But sadly it was never built.

First Engine

• In the 18th century a one of a kind technology was developed, which is being still used, i.e. engine with cylinders and pistons.

• But it took more than five decades to make this new technology efficient enough to make a vehicle move on its own.

• The cars being made in England in the 19th were more like trains not moving on rails.

First Successful Attempt

• The first vehicle to own under its own power whose record is there was designed by Nicholas Joseph Cugnot constructed by M. Brezin in 1769.

• It had a open boiler piped to the cylinder.• A replica of which is on display at Conservatoire

des Arts et Metiers, in Paris.• Its purpose was to haul canons around the town• And its top speed was 2 mph, as fast as anyone

would want to go on the cobbled streets of Paris.

Change In Fuel To Suit New Mechanism

• After the open boilers there was need for internal combustion engines.

• But this had to wait until suitable fuel was available.

• Gunpowder was tried but didn’t work out.• Coal gas was used after the failure of

gunpowder.

Coal Gas Cars

• A French named Etienne Lenior patented the first practical gas engine in 1862.

• It had a one-half horsepower engine, a bore of 5 inch, 24 inch stroke.

• It was big and heavy and turned 100 rpm.• Lenoir died broke in 1900.• Lenoir was claimed to be running on benzene.– If so then it was the first to run on petroleum based

fuel.

Change in mechanism

• Lenoir had a separate mechanism to compress the gas before combustion.

• In 1862, Alphonse Bear de Rochas figured how to compress the gas in the same cylinders in which it we to burn, which we still use.

• This process of bringing the gas into cylinder, compressing it, combusting the compressed mixture, then exhausting is known as Otto Cycle or four cycle engine.– Dailmer and Benz got the patent by claiming it from de

Rochas

THE VERY FIRST DRIVE

• In January 1888, Bertha Benz, in an effort to popularise her husband's invention, took the very first public drive in an automobile, in one of the Newly Constructed Patent Motorwagen automobiles-from Mannheim to Pforzheim, with her sons Richard and Eugen.

• She helped make the car popular. Many people at this time were afraid of using cars. Her pressure helped sway public opinion of the time.

The First Hybrid

• After steam and fuel using cars, Ferdinand Porsche in 1901 developed a hybrid car.

• Lohner-Porsche Mixte Hybrid, the first gasoline and electric hybrid automobile.

• But since gasoline was cheaper at that time, it was not much famous.

• Toyota released Toyota Prius in Japan in 1997, and it was greeted gladly because of worldwide increase in prices of petroleum .

Cars For The Public

• In 1908, Henry Ford produced the model T.• It had a 20 HP, four cylinder.• Top speed of 45 mph.• Weighed about 544 kg.

First fuel injection car

• The first direct fuel injectioncars hit the market in 1951.

•  The Gutbrod Superior and Goliath GP 700 E

Catalytic Converters

• In January 1956, Eugene Houdry invents the oxidation catalyst as a solution to the smog in Los Angeles at the time. Houdry was worried about the impact of car emissions on air pollution and founded a special company, the Oxy-Catalyst Company, which was to develop catalytic converters for gasoline engines. This idea was far ahead of its time.

FIRST TIME A CAR HITS 1000KMPH

• As man seeks to go faster and faster on land, the rocket car "Blue Flame" tops 1000 km/h in Bonneville Salt Flats, Utah, USA.

Change In Fuel Due To Destruction

• Forest destruction prompts unleaded petrol introduction

• Reacting to the destruction of forests, the German federal government decided to force the introduction of unleaded petrol engines in new cars.

The First Fuel Cell Sedans

• The first prototype was built by Honda in 1999.But they haven’t started the mass production yet.

• The latest fuel cell which is set to hit the market has been made by Toyota. – It is a hybrid.
