The word technology refers to the making, modification, usage, and knowledge of tools, machines, techniques, crafts, systems, and methods of organization, in order to solve a problem, improve a preexisting solution to a problem, achieve a goal, handle an applied input/output relation or perform a specific function. It can also refer to the collection of such tools, including machinery, modifications, arrangements and procedures. Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments.

In this paper I‘m going to introduce the Diesel Engine. It is a review, in witch I am going to gather information about this invention and my topics will be in three parts: first is Rudolf Diesel biography, second how diesel engines work, its types and also advantages and disadvantages and safety ofcourse. This topic, which I have chosen, is really relevant, because the diesel engine became widespread in many other applications, however, such as stationary engines, submarines, ships, and much later, locomotives, trucks, and in modern automobiles.
Diesel technology is constantly being improved. Government pressure to produce low-emission diesel engines for passenger vehicles, trucks, buses, and farm and construction equipment has resulted not only in low-sulfur diesel fuels but also specialized catalytic converters, advanced filters, and other devices to cut down or destroy toxic emissions.
Rudofl Diesel. Biography
Diesel was born in Paris, France in 1858 the second of three children of Elise (born Strobel) and Theodor Diesel. His parents were Bavarian immigrants living in Paris. Theodor Diesel, a bookbinder by trade, left his home town of Augsburg, Bavaria, in 1848. He met his wife, a daughter of a Nuremberg merchant, in Paris in 1855 and became a leather goods manufacturer there. Rudolf Diesel spent his early childhood in France, but as a result of the outbreak of the Franco-Prussian War in 1870, his family (as were many other Germans) was forced to leave. They settled in London. Before the war's end in 1874, however, Diesel's mother sent 12-year-old Rudolf to Augsburg to live with his aunt and uncle, Barbara and Christoph Barnickel, to become fluent in German and to visit the Königliche Kreis-Gewerbsschule (Royal County Trade School), where his uncle taught mathematics.
At age 14, Rudolf wrote a letter to his parents stating that he wanted to become an engineer. After finishing his basic education at the top of his class in 1873, he enrolled at the newly-founded Industrial School of Augsburg. Two years later, he received a merit scholarship from the Royal Bavarian Polytechnic of Munich, which he accepted against the wishes of his parents, who would rather have seen him start to work.
Diesel understood thermodynamics and the theoretical and practical constraints on fuel efficiency. He knew that as much as 90% of the energy available in the fuel is wasted in a steam engine. His work in engine design was driven by the goal of much higher efficiency ratios. After experimenting with a Carnot Cycle engine, he developed his own...
