HISTORY OF THE AUTOMOBILE

 HISTORY OF THE AUTOMOBILE

1. In 1769, a french Engineer captain Nicholas Cugnot, built the first vehicle propelled by its own Power

2. It was a three wheeler, four-seater vehicle fitted with a steam engine. It attained a speed of about 2 ½ m.p.h. for 15 minutes

3. In1880 , German and French efforts developed an internal combustion engine vehicle, which was used to carry fruits. The present day automotive is the development of this vehicle.

4. In1885 Benz in Germany built a tricycle propelled by an internal combustion engine.

5. In 1885-86, Gottlieb Daimler patented an internal combustion engine in Germany and a year later it was running in a vehicle.

6. In 1895, ChArles E. Duryea and Elwood J.Haynes in America developed experimental automobiles. In this year, Panhard and levassor in France also developed a car which, with minor exception, incorporated the chief features of the automobile as we know it today.

7. In 1890-1895, the European designers were also active in the development of the automobile

8. In 1895 , the early Panhard in France had the engine placed in the front of a chassis, hooked up a sliding gear transmission ; and incorporated brake pedals , clutch and accelerator.

9. In 1990, the design of the automobile was so improved that it awakened the public to the fact that this new form of transportation was really practical for use.


10. In 1906, the production and sale of these vehicles becomes a business.

11. Before 1906, many of the great names around which the world's largest manufacturing industry was to be built in America had already begun to manufacture the automobile vehicles. Packard, Autocar, Oldsmobile,White ,Buick, Overland, Ford, Cadillac- all these names were on motors vehicles before 1905. Pierce-Arrow, Locomotive, Maxwell, Franklin and Peerless were also important in their time in the technical and commercial development of the motor vehicle.

12. In 1908, Ford started his model with an intial run of 20,000 vehicles, an output unheard at that time . This was the period when the designer’s chief objective was to make his vehicle run in mass production at the lowest possible price.


13. In 1920, there was a gradual change and refinement in automobile design. It was clear by that time the spark ignition gasoline engine was to be the power plant of the modern motor vehicle. Water cooled engines were almost universal. The sliding gear transmission had established itself as predominant. The poppet valve was used in a almost every engine design. Engines were in all located in the front of the chassis.

14. In this period, the major improvement were made in every car feature. The designer tried to produce a vehicle which will function at all times under all conditions and which will be comfortable to ride and easy to operate. Increased life of tyres, independent front wheel suspension, four wheel hydraulic brakes, high compression ratio, high power, use of new materials, hundreds of other changes have been made.

15. Conditions change gradually chassis and change reliability came to be normal expectancy. The car owners required greater riding comfort and easiness in operation.

16. In recent years, the passenger car chassis and construction has been forced to shape itself to predesigned bodies, while in the field of truck design body chassis problems now get simultaneous consideration to a greater extent than ever before. Fluid flywheel, free-wheeling , over riding, automatic transmission and many other newer features are in the today’s car. The diesel engine was invented only a few years after the spark-ignition engine. Cars had engines in the rear before they had them in the front.

17. The design development of recent years has provided the owner with cars that are safer, easier to drive, more reliable and comfortable. The car owner of yesterday had to know something about repairing his vehicle. The driver who once was happy to have his car run, now he wants to repair it. The old driver was glad to have an open body instead of a box to sit in. But today the driver likes closed body which protects him from accidents, Strom, rains , and sun. The modern trends have created now opportunity for the professional repairman to the owner of a car. It is interesting now to have knowledge of working of an automobile vehicle in the social life.

18. It is of the whole history of the development of automobile vehicle which emphasizes a knowledge of basic principles as the unifying link between the past, present and future.

VALUE TIMING DIAGRAM OF A FOUR STROKE, OTTO CYCLE ENGINE

  VALUE TIMING DIAGRAM OF A FOUR STROKE, OTTO CYCLE ENGINE It has already been explained in the operation of four stroke, Otto cycle engine that the inlet valve opens during the suction stroke and the exhaust stroke and the exhaust valve opens during the exhaust stroke. The exact moment at which each of the valves opens and closes with reference to the position of the piston and crank can be show graphically in a diagram. This diagram is known as valve timing diagram. Theoretically, the inlet valve opens exactly at the beginning of suction stroke and closes at the end of the stroke. Both the valves close during power and compression stroke. The exhaust valve opens exactly at the beginning of exhaust stroke and closes at the end of the stroke. The theoretical valve timing diagram for a four stroke Otto cycle engine in shown in diagram. The opening and closing valves with reference to the position of piston and crank shaft during the four strokes are described as follow. 1.  ...

Engine Tuning in briefly

  Engine Tuning Engine tuning is more frequently required in modern high compression engine which are more sensitive to variation from specifications than the earlier slow speed low output engines. To maintain an engine at peak performance and economy it must be kept in good condition with all components upto specifications. Often during the engine tuning several conditions will be found which must be corrected to restore the engine to like new condition TUNING PROCEDURE A typical tuning or tune up procedure is given below, which includes visual and mechanical check and also check with instruments. Some of the checks are not related to the engine but should be done for the safety purpose. 1. Loose spark plug start engine to blow out carbon and dirt, shut off engine and remove plug. 2. Test engine compression. 3. If the compression ratio not upto specifications perform engine service that will eliminate the troubles. if the compression is all right re install the spark plug. 4. R...

Four stroke Petrol engine (spark ignition)

Introduction : The modern petrol engines operate on Otto cycle this cycle was introduced by German scientist Otto in 1876. Although it was described by french scientist Beande Roches in 1862.  Mainly Four strokes in the Petrol engines. 1. Suction stroke. 2. Compression stroke. 3. Power (working, expansion) stroke 4. Exhaust stroke.       Suction stroke :     During this stroke the the piston moves downword by the crankshaft which is revolved by the momentum of the flywheel & the power generated by the electric motor the inlet valve remains open & exhaust valve is closed during stroke. The downword movement of the piston sucks the air- fuel mixture in the cylinder from the carburettor through the open inlet valve. And the petrol mixed with air, this stroke complete here now the process move the next stroke.       Compression stroke :     During the compression stroke the piston moves upward direction and compressing the...
