Introduction and type of automobiles

Hello friend's, so in this post we will talk about introduction and type of automobile.

1. Introduction
An automobile is a self-propelled vehicle that is used to transport passengers and goods on land.  A vehicle is a machine used to transport passengers and goods.  A self-propelled vehicle is one in which the power required for propulsion is produced from within.  Airplanes, ships, motor boats, locomotives, cars, buses, trucks, jeeps, tractors, scooters, motorcycles are examples of self-propelled vehicles.  Motor vehicle is another name for self-propelled vehicle driven on the ground.  Thus, the automobile is a type of vehicle that is self-propelled and used for the purposes of transportation on land.  Cars, buses, trucks, jeeps, tractors, scooters, motorcycles are examples of automobiles.  Since an automobile is driven on land, it differs from other types of self-propelled vehicles, such as airplanes, helicopters, rockets, ships, motor boats, locomotives.

Automobile engineering is a branch of engineering in which we all study about automobiles and practice promoting them.  The term "automotive engineering" has the same meaning.

Mobile or motive means, which can run.  Automobile or automotive means one who can walk on his own.  A railway wagon cannot carry itself on a rail if it is not pushed or pulled by external force.  If not pulled by external force, a trolley cannot carry itself on the road.  The railway wagon is pulled on the rail by railroad.  The trolley is pulled onto the road by an automobile which can be a jeep or tractor.  In automobile engineering, we study about self-propelled vehicles such as cars, buses, jeeps, trucks, tractors, scooters, motorcycles.  Aeronautical engineering deals with airplanes, helicopters, rockets, etc., which fly in the air.  Marine engineering is related to ships, motor boats, etc., which flow in water.

Different names of automobiles:
 1. Auto
 2. Automobile
 3. Auto buggy
 4. Autocar
 5. Car
 6. Motor Car
 7. Motor
 8. Automotive
 9. Motor Wagon
 10. Motor Coach
 11. Horseless cart

(iii) Electric Cab - Battery Truck, Forklift.
(iv) Steam Carriage - Steam Road Roller.
(v) Gas vehicle - CNG vehicle.

4. Number of wheels:
(i) Two-wheeler - Mopeds, Scooters, Motorcycles.
(ii) Three Wheeler - Tempo, Road Roller.
(iii) Four Wheeler - Car, Jeep, Bus, Tractor.
(iv) Six wheelers - trucks, tenors, gun carriage vehicles.

VALVE TIMING DIAGRAM OF A FOUR-STROKE, OTTO CYCLE ENGINE

Hello friend's in this post we will talk about valve 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 valve opens during the exhaust stroke. The exact moment at winch each of the valves opens and closes with reference to the position of piston and crank can be shown 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 remain closed during compression and power strokes. The exhaust valve opens exactly at the beginning of exhaust stroke and closes at the end of stroke. The theoretical valve timing diagram for a four-stroke Otto cycle engine is shown in Fig. 3.3. The opening and closing of valves with reference to the position of piston and crank shaft during the four strok...

PRESSURE-VOLUME DIAGRAM OF FOUR-STROKE, OTTO CYCLE ENGINE

Hello friend's in this post we will talk about pressure - volume diagram of four - stroke, otto cycle engine Fig. 3.8 shows theoretical p-v diagram of a four-stroke Otto cycle engine. During the suction stroke, the charge is admitted in the cylinder increasing the volume from 1 to 2, at the atmospheric pressure. Cylinder volume is the sum of clearance volume and stroke volume. During the compression stroke, the charge is compressed from 2 to 3. Volume decreases to clearance volume and pressure rises. The compressed charge is ignited at constant volume, which increases the pressure as represented by 3- 4 line. During the working stroke the volume increases and pressure decreases as represented by 4-5line. At 5, the exhaust valve opens and exhaust takes place at constant decreases the pressure suddenly as represented by 5-2 line. Finally the piston moves onward rushing out the exhaust gases at atmospheric pressure as represented by 2-1 line. The volume again decreases to clearance vo...

History of Automobile

Hello friend's, so in this post we will talk about the history of Automobile. In 1769, Captain Nicolas Cagnot, a French engineer, built the first road vehicle powered by his power. It was a three-wheeler, four-seater vehicle fitted with a steam engine.  It achieved a speed of about 2 m.p.h.  For 15 minutes. In 1880, German and French efforts developed an internal combustion engine vehicle, which was used to carry fruits.  The current vehicle is a development of this vehicle. In 1885, Benz in Germany built a tricycle powered by an internal combustion engine. In 1885 - 1886, Gottlieb Daimler patented an internal combustion engine in Germany and a year later it was running in a vehicle, In 1895, Charles E. in America.  Duria and Ellwood J.  Hans developed experimental automobiles.  In this year, Panhard and Levassor in France also developed a car which, with minor exceptions, incorporated the main features of the automobile as we know it today. In 1890 - 1895,...
