Engine Full Details With Definition.


The engine is a mechanical term used in Automobile vehicles. An Automobile is a self-propelled vehicle that is used for the transportation of passengers and goods. A railway wagon cannot move itself on the rails if it is not pushed or pulled by an external force. In automobile engineering, we study cars, bikes, buses, and jeeps like self-propelled vehicles, which can move on the road or air. To move these kinds of vehicles we need some internal or external force. This kind of force is generated from the most complicated part named, Engine. 


An engine is a device that can repeat its activity again and again by maintaining a proper sequence and also converting one energy to another energy. Here the chemical energy is converted into mechanical energy. 


Human power was focused on the use of simple engines, like treadmills, windlass and ropes, pulleys, and blocks. By the 1st century AD, cattle and horses were used in mills, to drive machines. 

In the 13th century, the solid rocket motor was invented in china, which is driven by gunpowder. After this invention, it spreads all across Europe. Internal combustion piston engines were tested in France in 1807 by de Rivaz. Later on, Etienne Lenoir made successfully Internal Combustion Engine 1860. 

In 1877 the Otto cycle was discovered by Nicolas Otto, which worked much better and produces power to transport things. This Otto cycle engine is now used in Automobile vehicles. 


An Engine can be put into a category according to two criteria-
  • The form of energy it accepts in order to create motion 
  • The type of motion it outputs. 
The energy is basically used by heat, nuclear reaction, or electrically. Basically, heat engines are more often used in Automobile vehicles. In recent days Electrical energy is used to move road or air-self-propelled vehicles.
