Marine Power Plants

Posted on by

The main means of increasing capacity and efficiency of marine diesel power plant is turbocharged. Submission of the additional amount of air cylinders and, correspondingly, increase supply Fuel duty cycle, resulting in an increase in power a diesel power plant. Pressure diesel exhaust is 1.5-2 times higher than that of a gasoline engine that allows you to turbocharger provide boost and avoid inherent in gasoline engines with turbo failure – 'turboyamy'. In many diesel engines installed cooler nadduvaemogo air. These structural measures help to raise mass filling the cylinders and much, sometimes several times, to increase capacity.

Turbocharging improves combustion and reduces the hardness of work and loss of power. However, a diesel power plant with turbo has some disadvantages, mainly related to the reliability of the turbocharger. Resource turbo diesel engine is much smaller resource and usually does not exceed fifteen thousand hours. The turbine has high requirements for the quality of lubricating oil. Faulty turbine can totally disable the engine.

And his own life forced the engine slightly lower than the same air of diesel. The fuel system equipment Common-Rail – a modern solution to engine building. In each section a diesel engine high pressure pump pumps the fuel into the "separate" fuel line (going to a particular nozzle). The tubes are thick enough. In this case, when the high pressure 130-270 kg / cm on it "is run" portion of the fuel TTVD swells like boa, swallow prey. And once it goes into the fuel injector TTVD again compressed. This leads to the fact that after a specified portion fuel injector to necessarily "pumped" a tiny extra dose. This fuel, burning, increases fuel consumption, increases the opacity of the motor. Themselves as separate pipeline pulsation increased noise of the engine. C increasing the speed of rotation (rpm) modern automotive diesel engines (up to 4000-5000 r / min, (including marine diesel power plants) it has to deliver tangible inconvenience. A number of firms over time Engineers have found a solution to this problem for high-speed diesel engines. According to this scheme, fuel pump delivers fuel to the total pipeline – fuel rail, a kind of receiver. This middle tier is placed a constant volume of fuel which is under constant pressure – 1,300 bar. Nozzle opening is no longer fluid mechanics method (increase of pressure in the pipeline), and electronic – from a signal supplied to the solenoid injector. At its based computer assigns the right to operate the motor fuel and the time of its filing. Thus, the "snake" is not frantically pushes through the esophagus, "food", and operates in strict accordance with decisions taken by its computer. For marine diesel power unit – ignition engine fuel compression – it is very important, as the pressure in the combustion chamber increases more smoothly, without a "breakthrough." Therefore, ship diesel works less noisy. But most importantly – a system of Common-Rail eliminates injection into the combustion chamber "dosylnoy" portion of the fuel. Such designs of fuel injectors for engines made possible only in our time, this contributes to the development of electronics.

Knitting Machines

It has long been trying to beautify your life, people have sought to use the simplest materials to a combination of simple forms and patterns with unpretentious, reaching a high level of skill. Knitting originally appeared a mere utilitarian necessity, later turned into an art form. Knits have always valued very highly. For example, in Europe, knitted stockings to wear at first only very wealthy people. Knits were a gift, even for kings! In the XIV century in England there were special knitting school, who took the poor girls to give them the opportunity to earn. Thanks to one of these girls on the light appeared knitting machines. Invented by Englishman William Lee, to facilitate the work of his beloved.

But the proud knitter and did not respond to him in return. William decided to try to earn at least – and introduced his car Queen Elizabeth. But the Queen has banned the invention, reasoning that competition with the machines will ruin the poor knitters. William Lee died in poverty, unable to benefit from his own invention. But times have changed.

In Today, this art continues to evolve, enriched by new motives, composition techniques, modern materials. Hand knitting is costly in time and considerable patience. Most of the women engaged in knitting, sooner or later begin to think about purchasing a knitting machine. Knitting machines now – no problem, unlike recently when it was a very large deficit. Modern Knitting machines provide a great opportunity to realize their creative potential. Thanks to its automatic functions and knitting machines can easily perform complex operations that hand knitting is very tedious. On knitting machines can connect everything from socks to coats and hats and sweaters, as well as manage the process of knitting through a personal computer. One of them is a knitter Silver Reed, which will help you earn money if you're going to knit things for sale or order. Also you can save money, obvyazyvaya things for his family. Everyone will be happy with new things with minimal effort.

Graphics Programs

Do you think that can serve as a criterion in selecting software? Suppose you had to choose a program for a specific need. For example, take one of the most needed programs, which used every day, thousands and thousands of users for the Internet. I'm talking about Internet Explorer, or, in other words, the browser. Think of yourself when you were a newcomer to the Internet and viewed your first Web page … You just undecided browser, through which they viewed or set on your computer and have tried several browsers in their work? So, what is it all relates and to the fact that the choice of programs for some purpose it is necessary that many to choose from that was an alternative. Below is a list of the most interesting in my opinion programs in various categories: The Internet and the Web, Multimedia, Security, Graphics, Text, System, Rims and files. It is these categories of applications are in most cases, conventional polzovateli.Chtoby you can immediately see the program you cite references to separate application pages.

Using these links, you will appreciate the look and feel of the program on its screenshots and read a brief overview of a program. Favorite applications you can of course the same can skachat.Itak, a list of popular programs for Internet version of the portal and ZoneInternet SetiInternet ExplorerBrauzer, developed by programmers Microsoft. In Internet Explorer implements user-friendly interface that can be customized at will. In Internet Explorer are the so-called tabs (tab), there is support for CSS, and RSS-news feeds.

Internet Message Boards

Message boards appeared long before the advent of computers and the Internet in general and in particular, were, by and large, virtually the only way to disseminate information. It is true that in ancient times, large democratic way that is not used, being exclusively in the hands of the authorities: in Babylon knocked laws on stone pillars, in medieval England, royal decrees were posted on church doors. But with the passage Time has changed. A large wooden board on which anyone could post your ad for all to see or to find a proposal for the soul – that is, that for a long time to understand a message board. Second, electronic, the birth of boards can be called a BBS ('Bulletin Board Systems' – an electronic bulletin board), let this reincarnation and sufficiently far from the classical features of its prototype.

Ads on the Internet – a site that allows anyone person to place an ad on their pages. Most popular board determined, in large part by availability and ease of use. On the big Internet message boards attendance reaches many thousands of people a day, added daily by thousands of ads. To organize huge amounts of ads, they are usually divided into sections by topic: 'Sport', 'Household appliances', 'Property', 'Tourism' and so on. All boards can be divided into two main categories: moderated and unmoderated. In the latter case the board operates fully automatically and the visitor need only fill in the required form as it appears in the ad site and other visitors will be able to study it.

Times New Roman

Excellent shows and drawing melkodetalizirovannyh scenes on full high-definition signal. Above all praise and realistic colors. Picture juicy, natural colors, and there is a picture of the alyapistosti that frequent in the low-budget monitors. Signal of low quality BenQ G2220HDA little cleaning, but I must say that the possibility of monitor graphic chip is still strongly limited, and completely ruined the video, it is likely to show an "as is". Monitor uniquely kinoteatralen and can advise those who would like to watch a movie with high quality and in full high definition. Office-test As the test content, we used a test program Nokia Monitor Test, office applications, video and computer games. The first showed excellent brightness and contrast settings on the table brightness & contrast All gradient strips were clearly marked, the boundaries between the brightness gradients are marked clearly, from 10% brightness and up to 90%. Table kegl showed a clear image of the font Times New Roman down to 4 pin.

This is a very good indicator, since the font with serifs and a rather difficult to display. Since the test program, we actually went to office suites, more precisely on the most difficult to monitor every text editor Word. Here, too, as Nokia Monitor Test program, we have included Times New Roman font and in stages, starting with 2 pin and tried to print the text above. The result was almost the same as for the test program – for optimal performance of minimally small as comfortable with the font Times New Roman font is the fourth. The result definitely be commended Monitor BenQ G2220HDA. He proved himself an excellent and office worker and an avid kinoteatralom and avid gamer. The lack of DVI connectors, and HDMI, not much impact on the image, and the use of adapters removed many of the problems with konnektirovaniem. It should be noted that this product is probably the most low-end solution for anyone who wants to have a renderer resolution Full HD, today. Especially as the quality of matrix and CPU monitor perfectly complement the resolution of its display.
