Motor diesel de alumínio

Abstract

The engine is a machine which transforms chemical energy into mechanical energy. It's divided, mainly, in: cylinder block, cylinder head, crankcase, piston, crankshaft, turbocharger. It can be four or two strokes, intake, compression, expansion and exhaust stroke. In the production are used lots of compounds and qualities, they can be cast-iron, aluminum alloy, steel and titanium, according to the usage and it's own characteristic. The Aluminum Alloy are the most advanced, one of the reasons was the development of new casting techniques, such as thixocast, also called aluminum semisolid alloy casting, where the aluminum is a paste, lowing costs and making it more competitive than cast-iron. The advantages are mainly, corrosion resistance, recycling and the reliability on it's casts, they are thirty percent lighter, have a better heat dissipation. On this way, the manufacture of engines using aluminum is a reality without return, due to technological advances, and can be considered ecologically clean because of the reduced volume of material took of the nature.
