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". Most mechanical devices invented during the industrial revolution were described as engines?the steam engine being a notable example. However, the original steam engines, such as those by Thomas Savery, were not mechanical engines but pumps. In this manner, a fire engine in its original form was merely a water pump, with the engine being transported to the fire by horses.
In modern usage, the term engine typically describes devices, like steam engines and internal combustion engines, that burn or otherwise consume fuel to perform mechanical work by exerting a torque or linear force (usually in the form of thrust). Examples of engines which exert a torque include the familiar automobile gasoline and diesel engines, as well as turboshafts. Examples of engines which produce thrust include turbofans and rockets.
When the internal combustion engine was invented, the term "motor" was initially used to distinguish it from the steam engine?which was in wide use at the time, powering locomotives and other vehicles such as steam rollers. "Motor" and "engine" later came to be used interchangeably in casual discourse. However, technically, the two words have different meanings. An engine is a device that burns or otherwise consumes fuel, changing its chemical composition, whereas a motor is a device driven by electricity, air, or hydraulic pressure, which does not change the chemical composition of its energy source.3 However, rocketry uses the term rocket motor, even though they consume fuel.
A heat engine may also serve as a prime mover?a component that transforms the flow or changes in pressure of a fluid into mechanical energy.4 An automobile powered by an internal combustion engine may make use of various motors and pumps, but ultimately all such devices derive their power from the engine. Another way of looking at it is that a motor receives power from an external source, and then converts it into mechanical energy, while an engine creates power from pressure (derived directly from the explosive force of combustion or other chemical reaction, or secondarily from the action of some such force on other substances such as air, water, or steam).5
Devices converting heat energy into motion are commonly referred to simply as engines.6

Self-replacement car parts
While servicing cars is not a very cheap services, it should convey our car under the care of a specialist. The skilled person, who has not only appropriate computer software to diagnose the cause of the failure, but also often many years of experience in this field certainly much better cope with the odd broken car than an amateur. It is true that many people choose to self repair the car, however, you may find that the replacement parts on your own can even lead to larger faults in our car. Then the cost of repair can be much more sensible for the portfolio, so it is very worthwhile.
What better to choose - the original car parts or replacements?
As you know, the original car parts can sometimes be very expensive, especially if we think about replacing parts in the car with the high-end class. Many people are looking for savings decides to invest in a used auto parts or replacements. Whether in this case the higher the price of a higher quality product and whether deciding on a replacement for a mistake? It actually depends on the individual case. Sometimes it may be that the replacement is just as valuable as the original part, and it is not necessary to install the original to the efficient operation of our car. However, there are also cases in which the replacement is very fast operation due to the lower quality of the product and must again replace the part.
