Historical facts about electric motor

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.

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 windings

Content for beginners car fans

Cars are a rather complicated layouts and worth to each control you have knowledge of the most relevant information in this regard. First of all, take a look at the information on the basic elements of the construction of the car. These include not only the engine and steering wheel, but also many related parts, for example, with the propulsion system. More than one part of the car is completely black magic to people not connected in any way with the automotive industry. Some knowledge in this area is necessary, for example when driving course, but a lot of people quickly forget obtained message. It is worth it to remember, especially because it’s easier, we can use the machine as we know it.

An engine of this type

Blower scavenged
Diagram of uniflow scavenging

Using a separate blower avoids many of the shortcomings of crankcase scavenging, at the expense of increased complexity which means a higher cost and an increase in maintenance requirement. An engine of this type uses ports or valves for intake and valves for exhaust, except opposed piston engines, which may also use ports for exhaust. The blower is usually of the Roots-type but other types have been used too. This design is commonplace in CI engines, and has been occasionally used in SI engines.

CI engines that use a blower typically use uniflow scavenging. In this design the cylinder wall contains several intake ports placed uniformly spaced along the circumference just above the position that the piston crown reaches when at BDC. An exhaust valve or several like that of 4-stroke engines is used. The final part of the intake manifold is an air sleeve which feeds the intake ports. The intake ports are placed at an horizontal angle to the cylinder wall (I.e: they are in plane of the piston crown) to give a swirl to the incoming charge to improve combustion. The largest reciprocating IC are low speed CI engines of this type; they are used for marine propulsion (see marine diesel engine) or electric power generation and achieve the highest thermal efficiencies among internal combustion engines of any kind. Some Diesel-electric locomotive engines operate on the 2-stroke cycle. The most powerful of them have a brake power of around 4.5 MW or 6,000 HP. The EMD SD90MAC class of locomotives use a 2-stroke engine. The comparable class GE AC6000CW whose prime mover has almost the same brake power uses a 4-stroke engine.

An example of this type of engine is the Wärtsilä-Sulzer RTA96-C turbocharged 2-stroke Diesel, used in large container ships. It is the most efficient and powerful internal combustion engine in the world with a thermal efficiency over 50%.9101112 For comparison, the most efficient small four-stroke engines are around 43% thermally-efficient (SAE 900648);citation needed size is an advantage for efficiency due to the increase in the ratio of volume to surface area.

Kwestia przewozu grupy osób


Transport regionalny dla przykładu autokary zabrze to znakomity sposób na podróż ze zorganizowanymi grupami. Grupy dzieci, sparingi drużyny w innym mieście lub każda potrzeba podróży. Kilka słów o podróżach.

Wygoda w autokarach

Autokary duże i małe spełniają jedną, podstawową funkcję- maja przewieźć grupę osób na wskazane miejsce o wskazanym czasie. Jednak autokary różnią się od siebie na różnych płaszczyznach, co wpływa na długość podróży i jej wygodę dla pasażerów. Mamy duże autokary z miejscami do spania, klimatyzacją, toaletą, telewizją, a nawet dostępem do Wi-Fi.

Mniejsze lub starsze autokary mają ograniczony dostęp do powyższych udogodnień, ale i tak potrafią być komfortowe dla pasażera. Ważne są np. wygodne siedzenia, czy choćby ogólna sprawność i stan całego pojazdu. Jeszcze jedna sprawa, która ma spore znaczenia na przebieg i bezpieczeństwo całej podróży to oczywiście kierowca, a dobrego kierowcy nie zastąpi nawet najnowocześniejszy autokar.

Autokar hybrydowy

Napędy inne niż te na paliwo staja się coraz szerzej stosowane, do tego stopnia, że już w autobusach i autokarach montuje się napędy hybrydowe. Póki co jeden Polski producent wypuszcza takie właśnie autobusy, jednak niestety nie jeżdżą one u nas, a głównie w Niemczech. Jednak możliwe, ze wkrótce i u nas autobusy miejskie będą napędzane takim napędem.

Niektórzy prywatni przewoźnicy już zrobili inwestycje w takie pojazdy hybrydowe i można je wynająć na wycieczkę, czy nawet przejazd zagraniczny. Niestety jednak kilka lat przyjdzie nam poczekać zanim stanie się to standardowym napędem montowanym w pojazdach dalekobieżnych takich jak autokar.

Stare dobre Ikarusy

Firm produkujących autobusy jest dużo- mi jako pierwsza na przychodzi na myśl stara firma Ikarus. Ich autobusy jeździły po Polskich miastach odkąd pamiętam. Były to jedne z pierwszych autobusów przegubowych u nas w kraju. Siedziba tej firmy mieści się na Węgrzech w Budapeszcie. Produkowali również autobusy lotniskowe, trolejbusy oraz autobusy turystyczne. .Mimo problemów finansowych w trakcie trwania I i II wojny firma przetrwała i do dzisiaj ich autobusy i autokary jeżdżą po świecie. Przedsiębiorstwo dwa razy zmieniało właściciela, dzisiaj należy do Muszertechnika.

The choice of fuel for the car

Each fuel has its supporters and detractors. Experts automotive industry can give many reasons for allowing the selection of a suitable fuel for our car. However, not always the cheapest solution turns out to be the best for driver or car owner. For example, if you want to consider the option of supplying gas in our car, we must know that it is necessary to install proper installation. This is connected with considerable costs, but on the other hand, avoids the higher fees in the future. However, a group of drivers who decide to change their system already installed in your car, however, is quite sparse.

Automotive industry and economic impact

Around the world, there were about 806 million cars and light trucks on the road in 2007, consuming over 980 billion litres (980,000,000 m3) of gasoline and diesel fuel yearly.7 The automobile is a primary mode of transportation for many developed economies. The Detroit branch of Boston Consulting Group predicts that, by 2014, one-third of world demand will be in the four BRIC markets (Brazil, Russia, India and China). Meanwhile, in the developed countries, the automotive industry has slowed down.8 It is also expected that this trend will continue, especially as the younger generations of people (in highly urbanized countries) no longer want to own a car anymore, and prefer other modes of transport.9 Other potentially powerful automotive markets are Iran and Indonesia.10 Emerging auto markets already buy more cars than established markets. According to a J.D. Power study, emerging markets accounted for 51 percent of the global light-vehicle sales in 2010. The study, performed in 2010 expected this trend to accelerate.1112 However, more recent reports (2012) confirmed the opposite; namely that the automotive industry was slowing down even in BRIC countries.8 In the United States, vehicle sales peaked in 2000, at 17.8 million units.13

Safe on the road

While many people mistakenly believe that the pirates road only directing the car passenger or a motorcycle, more often unfortunately, can be seen that also other vehicles moving at extremely high speeds, especially on highways that are a little better than the standard highway . Many speeders, not at all applicable to the rules of the road that drivers of large trucks. They often mistakenly believe that the bigger the car on the road, the greater is the priority in traffic and forcing the other participants in the traffic, which can have very dangerous consequences. Going on a long trip, it must therefore be very careful with this kind of riding companions.

Hybrid vehicle – definition

A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine+electric motor,1 e.g. in diesel-electric trains using diesel engines and electricity from overhead lines, and submarines that use diesels when surfaced and batteries when submerged. Other means to store energy include pressurized fluid, in hydraulic hybrids.

Exclusive cars – only for the richest

Luxury car brand virtually since their inception are surrounded with an aura of mystery for average earners. Although over the years the exclusive, global brand cars were beginning to reveal its secrets to the outside world and show their offer, however, to this day, some car models are intended only for the richest people in the world. Luxury cars are a sign of prestige and good luck, while allowing very stand out in the crowd. Most of them are made of special materials and to achieve a surprisingly high speed. Another advantage of these cars is equipped with many different, sometimes very expensive gadgets.

Koszty związane z prowadzeniem wirtualnego biura

Posiadanie wirtualnego biura bardzo pomaga w prowadzeniu własnej firmy. Z jednej strony pomaga ono w organizacji pracy dużej firmy, a z drugiej strony pozwala na zaprowadzenie oszczędności w funkcjonowaniu niewielkiego przedsiębiorstwa, ponieważ pozwala na zredukowanie ilości zatrudnionych pracowników. Samo założenie wirtualnego biura jest bardzo prostym zadaniem, wystarczy znaleźć najlepszą dla siebie ofertę i podpisać stosowną umowę o realizację wybranych przez siebie zadań. Od zakresu działalności usługodawczej wirtualnego biura będzie zależało, jakie koszty będą związane z jego prowadzeniem. Natomiast posiadanie wirtualnego biura pozwala na przekazanie części obowiązków firmowych pracownikom takiego biura.

Zabezpieczenia biur wirtualnych

Rozwój współczesnego rynku pozwala na zakładanie różnych firm przez praktycznie wszystkie osoby chcące prowadzić własną działalność gospodarczą. Jednak nawet posiadanie dobrego pomysłu na rozwój własnej firmy może się okazać niewystarczające, jeżeli jej założyciel nie będzie sobie radził z praktycznym zastosowaniem różnych przepisów prawnych i nie będzie dobrze znał się na Internecie. Na szczęście z pomocą przychodzą twórcy wirtualnych biur, którzy sami zajmują się nie tylko ich tworzeniem, ale też wyposażeniem ich w odpowiednie oprogramowanie. Dbają także o to, aby zostały one dobrze zabezpieczone zarówno przed atakami hakerów, jak i przed różnymi wirusami. Posiadają także specjalistów z zakresu dokonywania napraw oprogramowania.

Zawarcie umowy z firmą prowadzącą wirtualne biuro

Rozpoczęcie współpracy z firmą prowadzącą wirtualne biuro opiera się na podpisanej umowie. W takiej umowie zawarte będą warunki wzajemnej współpracy i dokładnie wypunktowane obowiązki pracowników wirtualnego biura. Będą oni odpowiadali za jakość funkcjonowania wirtualnego biura, a od zadowolenia ich klienta zależeć będzie czy umowa na mocy której działa wirtualne biuro będzie przedłużana. Po okresie dobrej i zadowalającej współpracy będzie można podpisać najkorzystniejszą dla obu stron umowę na czas nieokreślony. Klienci będą mieli także możliwość poprosić o rozszerzenie obowiązków wirtualnego biura, a dzięki temu ich codzienna praca będzie jeszcze lepiej zorganizowana. Posiadanie zadowolonych klientów pozwala także wirtualnym biurom na rozszerzanie swojej działalności.
