Service and maintenance is sometimes the best way to avoid any defects and malfunctions that may occur when you least expect. Regular technical inspections, temporary repairs, small fixes - all of this together ensures us that our car will be smooth and will serve us well for a long time. Every vehicle owner should be very serious about such issues, because often they are able to protect themselves against higher costs and dangers that entails faulty car. You should also know that periodic technical inspection is a legal obligation of the holder of the car, and the avoidance of risk of legal consequences.
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

Choosing an attractive car designed for gift
Sometimes, as a birthday present bought a car. This applies especially to round birthday, which celebrates particularly close to our person. In choosing an attractive car designed gift can help us staff car showroom, where you want to make the purchase. As part of the gifts we can also perform a review of the car before the first using the vehicle, and thus help a loved person save time that would be spent on driving the car services and we will make it an extra surprise. Knowing her Earning we can also treat it greater amount of engine oil, which will be able to enjoy for a long time.
