Piston Engines Picture a tube or cylinder that holds a snugly fitting plug. The plug is free to move back and forth within this tube‚ pushed by pressure from hot gases. A rod is mounted to the moving plug; it connects to a crankshaft‚ causing this shaft to rotate rapidly. A propeller sits at the end of this shaft‚ spinning within the air. Here‚ in outline‚ is the piston engine‚ which powered all airplanes until the advent of jet engines. Pistons in cylinders first saw use in steam engines. Scotland’s

A jet engine‚ like a rocket engine‚ is a reaction engine. It works by throwing mass in one direction and taking advantage of the reaction in the opposite direction. In the case of a jet engine‚ the engine burns fuel (like kerosene) with air from the atmosphere. The burning fuel heats and expands the air‚ and this hot air shoots out of the exhaust-end of the engine to create thrust. Most modern jet engines use a turbine to improve the efficiency of the engine and allow the engine to work at low speeds

COMMENTARY - REINDEER AND ENGINE This poem‚ "Reindeer and Engine" is by Josephine Jacobsen. It is set in a ’Finnish forest track’ where a reindeer is being chassed by a train. It flees from the light of the train as it ’runs’ forward trying to escape. This is a narrative poem because it tells a story from an omniscient point of view. It is written in four stanza’s each one telling a different part of the story. The first idea we come across is that of light. ’The great round eye’ in the first line

In The Belief Engine‚ James Alcock introduces two interesting components in our internal belief engine‚ the Critical-Thinking Unit‚ and the Memory Unit. These two corresponding items work hand and hand to help logical thinkers to understand the world around them through personally analyzing their own past without bias from the Emotional Response Unit‚ or any other conflicting counter-part. Critical thinking is not an innate ability. As mentioned in the article many of us are born with what Alcock

COMBUSTION ENGINES 6.1 Introduction Perhaps the best-known engine in the world is the reciprocating internal combustion (IC) engine. Virtually every person who has driven an automobile or pushed a power lawnmower has used one. By far the most widely used IC engine is the spark-ignition gasoline engine‚ which takes us to school and work and on pleasure jaunts. Although others had made significant contributions‚ Niklaus Otto is generally credited with the invention of the engine and with the

The Diesel Engine Diesel engines are very similar to the gasoline engine you may find in a car. They both are internal combustion engines‚ have a four stroke cycle‚ and convert chemical energy from fuel into mechanical energy. However‚ the manner in which the combustion stroke is attained sets these two engines apart‚ and although a seemingly meaningless change‚ a large change in efficiency results. (Diesel Engines vs. Gasoline Engines) The diesel engine was invented by Rudolf Diesel in 1892
