PETROLEUM

Tallinn 2013 Ott Speek Subject: English Geodesy Study group: GI-21b PETROLEUM PRESENTATION Petroleum (L. petroleum, from Greek: Πέτρα (rock) + Latin: oleum (oil) is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. The name Petroleum covers both naturally occurring unprocessed crude oils and petroleum products that are made up of refined crude oil. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. This comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir characterization (mainly in terms of porosity and permeable structures). It is refined and separated

Shipreport

1)Main machinery On a ship, the engine room, or ER, is the propulsion machinery spaces of the vessel. To increase the safety and damage survivability of a vessel, the machinery necessary for operations may be segregated into various spaces. The engine room is one of these spaces, and is generally the largest physical compartment of the machinery space. The engine room houses the vessel's prime mover, usually some variations of a heat engine - diesel engine, gas or steam turbine. On some ships, the machinery space may comprise more than one engine room, such as forward and aft, or port or starboard engine rooms, or may be simply numbered. 1.1)Main engine The engine room of a motor vessel typically contains several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. They typically burn diesel oil or heavy fuel oil, and may be able to switch between the two. There are many propulsion arrangements for motor

2-stroke tuners handbook tuners

 Two-Stroke TUNER’S HANDBOOK By Gordon Jennings Illustrations by the author Copyright © 1973 by Gordon Jennings Compiled for reprint © 2007 by Ken i  PREFACE Many years have passed since Gordon Jennings first published this manual. Its 2007 and although there have been huge technological changes the basics are still the basics. There is a huge interest in vintage snowmobiles and their “simple” two stroke power plants of yesteryear. There is a wealth of knowledge contained in this manual. Let’s journey back to 1973 and read the book that was the two stroke bible of that era. Decades have passed since I hung around with John and Jim. John and I worked for the same corporation and I found a 500 triple Kawasaki for him at a reasonable price. He converted it into a drag bike, modified the engine completely and added mikuni carbs and tuned pipes. John borrowed Jim’s cop

Turbo ja kompressor(inglise keeles)

Since the invention of the internal combustion engine, automotive engineers, speed junkies and racecar designers have been searching for ways to boost its power. One way to add power is to build a bigger engine. But bigger engines, which weigh more and cost more to build and maintain, are not always better. Another way to add power is to make a normal-sized engine more efficient. You can accomplish this by forcing more air into the combustion chamber. More air means more fuel can be added, and more fuel means a bigger explosion and greater horsepower. A turbo/supercharged engine produces more power overall than the same engine without the charging. Both superchargers and turbochargers do this. The difference between the two devices is their source of energy . TURBOCHARGER When people talk about race cars or high-performance sports cars, the topic of turbochargers usually comes up. Turbochargers also appear on large diesel engines. A turbo can significantly boost an engine's horsepowe
