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.
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: https://en.wikipedia.org/wiki/Electric_motor
Diesel cycle Main article: Diesel cycle P-v Diagram for the Ideal Diesel cycle.
The cycle follows the numbers 1?4 in clockwise direction. Most truck and automotive diesel engines use a cycle reminiscent of a four-stroke cycle, but with a compression heating ignition system, rather than needing a separate ignition system.
This variation is called the diesel cycle.
When buying a car from abroad we have to be careful if the seller does not deceive us, because there is no shortage of vehicles which, for example, have accidents and are sold as accident-free.
Then the car can really be in bad shape, although aesthetically looks good and inconvenience are covered.This creates a really big risk and it is worth to choose the service of your friends in this regard.
Imports of cars from abroad is often a way to earn a certain amount of money, so a lot of people lead such activities.
So let's go to a friend or a person with a command when you plan to buy this car..
