Aluminum-silicon alloy materials applied in the manufacture of parts of reciprocating internal combustion engines Part II

Abstract

This paper presents a systematic knowledge of the chemical composition, type of molding and treatment, mechanical and thermal properties, of aluminium-silicon (Al-Si) alloys applied in the manufacture of structural parts of reciprocating internal combustion engines (RICE), with the aim of providing support for the development of researches when compare, analyze or select the presented alloys. For which, a first paper was presented that revealed that structural parts of these types of engines are manufactured with Al-Si alloys. This second part establishes the importance that Al-Si alloys will have in reducing emissions of polluting gases, problematic that the world has. In response, the article presents the benefits and properties of Al-Si alloys of the series ANSI AA 3xx.0 and 4xx.0, being its low density which allows a lower fuel consumption compared to high density materials, for which are applied in structural parts of the RICE type Otto. A brief description of the manufacture of Al-Si alloy parts for RICE is also made. Finally, its present the structuring of a table that shows the ANSI AA 3xx.0 and 4xx.0 alloys applied in the manufacture of structural parts of RICE Otto, concluding that the technical information of the industrial applications of the alloys, have been developed and structured in a systematized way, to provide detailed and comparative knowledge between the properties.
