Vehicles from abroad

mot emissions failAs is well known, very popular in Poland you are purchasing used cars. This involves a much lower cost, so it is no wonder that involved missing.

Not less popular cars which were imported from abroad.

In countries in Western Europe, many cars are exchanged after a short time of operation, and therefore that their condition is really good, are re-sold in Poland and other countries.

Cars that have been used in Germany and France are often much less worn than the cars of the same vintage, which moved on Polish roads.

That is why so much interest in such cars.

Tuning on your own

Tuning cars gives them the most suitable vehicles sporty look.
Many cars and motorcycles looking for faster and more efficient machine when we add a few elements.

There's no denying that the tuning is often a form of gain recognition in society or gain friends, especially among younger drivers.

Almost every young boy wants to have a car, but not everyone can afford it.
Some elements, however, can replace their own.
With the necessary financial resources should in fact invest in tuning parts, and then personally carry out improvement of our vehicle.

Electric motor - history

mot emissions fail
Perhaps the first electric motors were simple electrostatic devices created by the Scottish monk Andrew Gordon in the 1740s.2 The theoretical principle behind production of mechanical force by the interactions of an electric current and a magnetic field, Amp?re's force law, was discovered later by André-Marie Amp?re in 1820.
The conversion of electrical energy into mechanical energy by electromagnetic means was demonstrated by the British scientist Michael Faraday in 1821.
A free-hanging wire was dipped into a pool of mercury, on which a permanent magnet (PM) was placed.
When a current was passed through the wire, the wire rotated around the magnet, showing that the current gave rise to a close circular magnetic field around the wire.3 This motor is often demonstrated in physics experiments, brine substituting for toxic mercury.
Though Barlow's wheel was an early refinement to this Faraday demonstration, these and similar homopolar motors were to remain unsuited to practical application until late in the century. Jedlik's "electromagnetic self-rotor", 1827 (Museum of Applied Arts, Budapest). The historic motor still works perfectly today.4 In 1827, Hungarian physicist Ányos Jedlik started experimenting with electromagnetic coils. After Jedlik solved the technical problems of the continuous rotation with the invention of the commutator, he called his early devices "electromagnetic self-rotors".

Although they were used only for instructional purposes, in 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and commutator.

The device employed no permanent magnets, as the magnetic fields of both the stationary and revolving components were produced solely by the currents flowing through their windingsŹródło:
