Quest 'image represents the birth of modern civilization This is the first engine that was designed by Augost Eight in 1876. Since then, the operating principle of the 4-stroke internal combustion engine has remained unchanged but the specifications are totally changed. Di'fatti engines then developed a few horses and the speed was reduced to a few hundred rounds per minute this was due to materials that were produced motors: cast iron, bronze and aluminum and the engine technology that was in its infancy, but now the engines are mostly light alloys and utraleggere who excellent mechanical properties and design of these engines are very sophisticated, precisely for this high-performance engines can reach speeds very close to 22,000 g / min and specific power of 300 hp / liter
