Internal combustion engine

The internal combustion engine is an engine in which the combustion of a fuel (normally a fossil fuel) occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine (ICE) the expansion of the high-temperature and high-pressure gases produced by combustion apply direct force to some component of the engine. The force is applied typically to pistons, turbine blades, or a nozzle. This force moves the component over a distance, transforming chemical energy into useful mechanical energy. The first commercially successful internal combustion engine was created by Étienne Lenoir.

             Animation of two-stroke engine in operation, with a tuned pipe exhaust.

The term internal combustion engine usually refers to an engine in which combustion is intermittent, such as the more familiar four-stroke and two-stroke piston engines, along with variants, such as the six-stroke piston engine and the Wankel rotary engine. A second class of internal combustion engines use continuous combustion: gas turbines, jet engines and most rocket engines, each of which are internal combustion engines on the same principle as previously described.

The ICE is quite different from external combustion engines, such as steam or Stirling engines, in which the energy is delivered to a working fluid not consisting of, mixed with, or contaminated by combustion products. Working fluids can be air, hot water, pressurized water or even liquid sodium, heated in some kind of boiler. ICEs are usually powered by energy-dense fuels such as gasoline or diesel, liquids derived from fossil fuels. While there are many stationary applications, most ICEs are used in mobile applications and are the dominant power supply for cars, aircraft, and boats.

Automobile

Automobile
AUTOMOBILE:An automobile, autocar, motor car or car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods. The term motorcar has also been used in the context of electrified rail systems to denote a car which functions as a small locomotive but also provides space for passengers and baggage. These locomotive cars were often used on suburban routes by both interurban and intercity railroad systems. It was estimated in 2010 that the number of automobiles had risen to over 1 billion vehicles, with 500 million reached in 1986. The numbers are increasing rapidly, especially in China and India. Etymology The word automobile comes, via the French automobile from the Ancient Greek word αὐτός (autós, "self") and the Latin mobilis ("movable"); meaning a vehicle that moves itself. The loanword was first adopted in English by The New York Times in 1899. The alternative name car is believed to originate from the Latin word carrus or carrum ("wheeled vehicle"), or the Middle English word carre("cart") (from Old North French), in turn these are said to have originated from the Gaulish wordkarros (a Gallic Chariot).                                                       Benz "Velo" model (1894) –entered into anearly automobile race as a motocycle

Eiffel tower (the achievement of engineers)

           A series of images showing the construction of the Eiffel Tower, 1887-1889.

The Eiffel Tower (French: La Tour Eiffel) is an iron lattice tower located on the Champ de Mars in Paris, named after the engineer Gustave Eiffel, whose company designed and built the tower. Erected in 1889 as the entrance arch to the 1889 World's Fair, it has become both a global cultural icon of France and one of the most recognizable structures in the world. The tower is the tallest structure in Paris^[10] and the most-visited paid monument in the world; 7.1 million people ascended it in 2011. The third level observatory's upper platform is at 279.11 m (915.7 ft) the highest accessible to public in the European Union and the highest in Europe as long as the platform of the Ostankino Tower, at 360 m (1,180 ft), remains closed as a result of the fire of August 2000. The tower received its 250 millionth visitor in 2010.

The tower stands 320 metres (1,050 ft) tall, about the same height as an 81-storey building. During its construction, the Eiffel Tower surpassed the Washington Monument to assume the title of the tallest man-made structure in the world, a title it held for 41 years, until the Chrysler Building in New York City was built in 1930. Because of the addition, in 1957, of the antenna atop the Eiffel Tower, it is now taller than the Chrysler Building. Not including broadcast antennas, it is the second-tallest structure in France, after the Millau Viaduct.

The tower has three levels for visitors. Tickets can be purchased to ascend, by stairs or lift (elevator), to the first and second levels. The walk from ground level to the first level is over 300 steps, as is the walk from the first to the second level. The third and highest level is accessible only by lift - stairs exist but they are not usually open for public use. Both the first and second levels feature restaurants.

The tower has become the most prominent symbol of both Paris and France, often in the establishing shot offilms set in the city.

7.WHAT  IS  CHEMICAL ENGINEERING? WHERE THE  CHEMICAL ENGINEERS WORK?

Chemical engineering is the branch of engineering that applies the physical sciences (e.g., chemistry andphysics) and/or life sciences (e.g., biology, microbiology and biochemistry) together with mathematics andeconomics to processes that convert raw materials or chemicals into more useful or valuable forms. In addition, modern chemical engineers are also concerned with pioneering valuable materials and related techniques – which are often essential to related fields such as nanotechnology, fuel cells and biomedical engineering. Within chemical engineering, two broad subgroups include 1) design, manufacture, and operation of plants and machinery in industrial chemical and related processes ("chemical processengineers"); and 2) development of new or adapted substances for products ranging from foods and beverages to cosmetics to cleaners to pharmaceutical ingredients, among many other products ("chemical productengineers").

7.PETROLEUM ENGINEERING

7.WHAT  IS  PETROLEUM ENGINEERING? WHERE THE  PETROLEUM ENGINEERS WORK?

Petroleum engineering is a field of engineering concerned with the activities related to the production of hydrocarbons, which can be either crude oil or natural gas. Exploration and Production are deemed to fall within the upstream sector of the oil and gas industry. Exploration, by earth scientists, and petroleum engineering are the oil and gas industry's two main subsurface disciplines, which focus on maximizing economic recovery of hydrocarbons from subsurface reservoirs. Petroleum geology and geophysics focus on provision of a static description of the hydrocarbon reservoir rock, while petroleum engineering focuses on estimation of the recoverable volume of this resource using a detailed understanding of the physical behavior of oil, water and gas within porous rock at very high pressure.

The combined efforts of geologists and petroleum engineers throughout the life of a hydrocarbon accumulation determine the way in which a reservoir is developed and depleted, and usually they have the highest impact on field economics. Petroleum engineering requires a good knowledge of many other related disciplines, such as geophysics, petroleum geology, formation evaluation (well logging), drilling, economics, reservoir simulation,reservoir engineering, well engineering, artificial lift systems, completions and oil and gas facilities engineering.
