Seiliger Cycle
The dual combustion cycle (also known as the mixed cycle, Trinkler cycle, Seiliger cycle or Sabathe cycle) is a thermal cycle that is a combination of the Otto cycle and the Diesel cycle, first introduced by Russian-German engineer Gustav Trinkler, who never claimed to have developed the cycle himself. Heat is added partly at constant volume (isochoric) and partly at constant pressure (isobaric), the significance of which is that more time is available for the fuel to completely combust. Because of lagging characteristics of fuel this cycle is invariably used for Diesel and hot spot ignition engines. It consists of two adiabatic and two constant volume and one constant pressure processes. The dual cycle consists of following operations: * Process 1-2: Isentropic compression * Process 2-3: Addition of heat at constant volume. * Process 3-4: Addition of heat at constant pressure. * Process 4-5: Isentropic expansion. * Process 5-1: Rejection of heat at constant volume.

Myron Seiliger
Мирон Павлович Зейлигер (1874–1952), (English transcription: Miron Pavlovich Zeyliger), birthname: ''Меер Пинхусович Зейлигер'' (English transcription: Meer Pinkhusovich Zeyliger), known as: Myron Seiliger, was a Russian physicist and university professor who developed the Seiliger cycle, a hypothetical model that describes how the Diesel engine works. Life and career Seiliger, who was born in Odessa, studied at the Institute of Technology in Saint Petersburg. Later, he became a professor there and lectured in thermodynamics and internal combustion engines. In 1910, Seiliger developed the dual cycle, which was later named Seiliger cycle after him. After the Russian Revolution The Russian Revolution was a period of Political revolution (Trotskyism), political and social revolution that took place in the former Russian Empire which began during the First World War. This period saw Russia abolish its monarchy and ad ..., Seiliger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otto Cycle
An Otto cycle is an idealized thermodynamic cycle that describes the functioning of a typical spark ignition piston engine. It is the thermodynamic cycle most commonly found in automobile engines. The Otto cycle is a description of what happens to a gas as it is subjected to changes of pressure, temperature, volume, addition of heat, and removal of heat. The gas that is subjected to those changes is called the system. The system, in this case, is defined to be the fluid (gas) within the cylinder. By describing the changes that take place within the system, it will also describe in inverse, the system's effect on the environment. In the case of the Otto cycle, the effect will be to produce enough net work from the system so as to propel an automobile and its occupants in the environment. The Otto cycle is constructed from: :Top and bottom of the loop: a pair of quasi-parallel and isentropic processes (frictionless, adiabatic reversible). :Left and right sides of the loop: ...

Diesel Cycle
The Diesel cycle is a combustion process of a reciprocating internal combustion engine. In it, fuel is ignited by heat generated during the compression of air in the combustion chamber, into which fuel is then injected. This is in contrast to igniting the fuel-air mixture with a spark plug as in the Otto cycle (four-stroke/petrol) engine. Diesel engines are used in aircraft, automobiles, power generation, diesel–electric locomotives, and both surface ships and submarines. The Diesel cycle is assumed to have constant pressure during the initial part of the combustion phase (V_2 to V_3 in the diagram, below). This is an idealized mathematical model: real physical diesels do have an increase in pressure during this period, but it is less pronounced than in the Otto cycle. In contrast, the idealized Otto cycle of a gasoline engine approximates a constant volume process during that phase. Idealized Diesel cycle The image shows a p-V diagram for the ideal Diesel cycle; where p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saint Petersburg
Saint Petersburg ( rus, links=no, Санкт-Петербург, a=Ru-Sankt Peterburg Leningrad Petrograd Piter.ogg, r=Sankt-Peterburg, p=ˈsankt pʲɪtʲɪrˈburk), formerly known as Petrograd (1914–1924) and later Leningrad (1924–1991), is the second-largest city in Russia. It is situated on the Neva River, at the head of the Gulf of Finland on the Baltic Sea, with a population of roughly 5.4 million residents. Saint Petersburg is the fourth-most populous city in Europe after Istanbul, Moscow and London, the most populous city on the Baltic Sea, and the world's northernmost city of more than 1 million residents. As Russia's Imperial capital, and a historically strategic port, it is governed as a federal city. The city was founded by Tsar Peter the Great on 27 May 1703 on the site of a captured Swedish fortress, and was named after apostle Saint Peter. In Russia, Saint Petersburg is historically and culturally associated with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
