AUTOMOTIVE ENGINES COMPONENTS DESIGN

AUTOMOTIVE ENGINES COMPONENTS DESIGN Unit - 1Mention classification of engineering materials.The engineering materials are mainly classified as metals and their alloys, such as iron, steel, copper, aluminium, etc. non-metals such as glass, rubber, plastics, etc. The metals may be further classified as Ferrous metals Non-ferrous metals.

What is Ferrous metals?The ferrous metals are those which have the iron as their main constituents. Examples: cast iron, wrought iron and steel. What is non-ferrous metals?The non-ferrous metals are those which have metals other than iron as main constituents such as copper, aluminium, brass, tin, zinc, etc. The non-metals are ceramic materials and organic materials. The ceramic materials are oxides, carbides and nitrides of various metals. Examples: glass, brick, concrete, cement, etc. The organic materials are polymeric materials composed of carbon compounds. Examples: Paper, rubber, plastic, wood, paints, etc.

Mention selection criteria for materials.The selection of material for designing purposes depends upon the following factors. availability suitabilitycostphysical propertiesmechanical properties Mention some physical properties of metals.The physical properties of metals are colour, size, shape, density, electrical, thermal conductivity and melting point.
