Consent Form | Cycle WorldAn engine or motor is a machine designed to convert one form of energy into mechanical energy. Electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air , and clockwork motors in wind-up toys use elastic energy. In biological systems, molecular motors , like myosins in muscles , use chemical energy to create forces and eventually motion. The word engine derives from Old French engin , from the Latin ingenium —the root of the word ingenious. Pre-industrial weapons of war, such as catapults , trebuchets and battering rams , were called siege engines , and knowledge of how to construct them was often treated as a military secret. The word gin , as in cotton gin , is short for engine.
How Engine Cooling System Works
Internal combustion engine
The core of the engine is the cylinder, with the piston moving up and down inside the cylinder. Single cylinder engines are typical of most lawn mowers, but usually cars have more than one cylinder four, six and eight cylinders are common. In a multi-cylinder engine, the cylinders usually are arranged in one of three ways: inline , V or flat also known as horizontally opposed or boxer , as shown in the figures to the left. So that inline four we mentioned at the beginning is an engine with four cylinders arranged in a line. Different configurations have different advantages and disadvantages in terms of smoothness, manufacturing cost and shape characteristics. These advantages and disadvantages make them more suitable for certain vehicles.
An internal combustion engine ICE is a heat engine where the combustion of a fuel occurs with an oxidizer usually air in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high- temperature and high- pressure gases produced by combustion applies direct force to some component of the engine. The force is applied typically to pistons , turbine blades , rotor or a nozzle. This force moves the component over a distance, transforming chemical energy into useful mechanical energy. The term internal combustion engine usually refers to an engine in which combustion is intermittent , such as the more familiar four-stroke and two-stroke piston engines, along with variants, such as the six-stroke piston engine and the Wankel rotary engine. A second class of internal combustion engines use continuous combustion: gas turbines , jet engines and most rocket engines , each of which are internal combustion engines on the same principle as previously described.
case of internal combustion engine, the combustion of fuel takes place inside the A brief description of these parts is given Materials used for engine parts.

The motorcycle is "a form of entertainment that can appeal only, one would think, to the most enthusiastic of mechanical eccentrics," Engineering magazine stated in Last year, four million motorcycles were in use in the United States alone. Whether relied upon as a primary means of transportation, used to provide weekend recreation, souped up and sped along for racing, or displayed as antique, millions of people across the world have shown that the novelty most definitely has not worn off. As might be imagined, the motorcycle evolved from a vehicle powered by sheer human energy—the bicycle. French bicycle maker Pierre Michaux and his sons Ernest and Henri first fitted a bicycle with cranks and pedals—precursors to the modern-day motor—in
