Why we are more and more often decide to buy car parts through the Internet?
For several years, we can see that the number of websites through which you can arrange the purchase of selected parts of our car is still increasing. It is associated not only with the fact that Moto is a very popular interest and a way to spend free time, especially among men, but also because thanks to this kind of news services can be carried out replacement of the parts in our car much cheaper way than using service cars by a specialist. Hence the popularity of this solution is still gaining strength and it can be expected that in the coming years is still the number of customers opting for online purchase of auto parts will increase.
A heat engine
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
car under control
Minor repairs of the car does not usually require a lot of time or money. Often, however, we ignore this type of failure - after all, they are not dangerous, and nowadays many people find it difficult to find even a brief moment to drive the mechanics and to verify the minor faults. Of course, this is a mistake. Few serious problem, which will be mishandled, could adversely affect other mechanisms and systems of the car. So if the failure is not remedied, it is likely to contribute to a much larger damages, and hence - the cost of repairs will increase significantly. Often in such a situation replacement parts are required, which of course affects the final price of the service mechanic. Not so it is worth delaying the service of the car, even if the problem with him seems to be harmless.
