Servicing cars is very much needed almost every driver. In the event of sudden failure of the car just a phone call to a friendly mechanic to help it through the phone indicate the source of the problem and identify a solution. However, most often it is necessary to visit a garage. I must admit that if we go about our work in this profession really honestly, we can even start earning well. Of course, the most profitable is to conduct your own garage, but working as a mechanic can also be one of the more rewarding physical activity. For many men, it is also very enjoyable because of the interest in automobiles.
Standard maintenance services
With the increasing number of cars is also increasing demand for services such as servicing cars. During the maintenance staff of people working on this, that our car was comprehensively tested in every respect. Even the slightest defect can in fact cause considerable danger on the road. The most common services they perform service technicians working in garages are primarily replacement car parts and ongoing maintenance. Sometimes there is a need to leave the car for a few days in the workshop in order to accurately and precisely mount the data elements or remedy the fault. In such cases, we can often expect us to provide transport from the service centers.
the internal combustion 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
