PDF | Aluminium engine blocks require the use of grey iron liners to resist wear from sealings mounted in pistons. Liners can be inserted into the piece after machining or can be castinto the block.
the substitution of aluminium for grey cast iron in passenger car engine blocks will continue in the future with greater impetus. The developments in the fi eld
Engine block The engine block is a single unit that contain all the pieces for the engine . The block serves as a structural framework of the engine and carries the mounting pad by which the engine is supported by the chassis The block is made of cast iron and sometimes aluminum for higher performance Vehicle The engine block is manufactured to ...
Gray iron is one of the oldest cast ferrous materials. In spite of competition from newer materials and their energetic promotion, gray iron is still used for those applications where its properties have proved it to be the most suitable material available.
Cast Iron. Most of grey cast irons have a chemical composition of to % carbon, 1 to 3% silicon, and the remainder is pure iron. Grey cast iron has less tensile strength and shock resistance than ductile iron or malleable iron, however its compressive strength is comparable to low and medium carbon steel.

Dec 17, 2015· GREY CAST IRON ALLOY Gray cast iron alloy have been the dominant metal that was used to manufacture conventional gaspowered engine blocks. Though extensive use of aluminum alloys has diminished the popularity of this material, it still finds wide use in dieselfueled blocks, where the internal stresses are much higher.
Cylinder block: A onepiece casting of heavily ribbed, weldable grey iron intake plenum runs the full engine length, providing even air distribution to the cylinders. Crankshaft: A press forging, induction hardened and counterweight for each cylinder is welded to the crankshaft and then ultrasonically examined to assure weld integrity.

The Engine. The engine was again of 65 degree configuration, with chaindriven twin overhead camshafts per bank, having a total capacity of 2418cc, with a bore and stroke of x 60mm, bearing factory type reference 135 CS. The cylinder block was cast iron, whilst the cylinder heads and various other castings were of a silumin alloy.
As with engine blocks, cylinder heads can be made of cast iron, or aluminum alloy. A head made of aluminum alloy is lighter than if it were made of cast iron. The piston, with its connecting rod and bearing, transfers the force of the combustion and expansion of the power stroke to the crankshaft.
NewGeneration Diesels Give Cast Iron a Boost. Before it was a production center for engine blocks and other auto parts, Detroit was famous for making castiron stoves. Now, 100 years later, few materials have fallen from grace in the automotive world like cast .
Cast iron is defined as an alloy of iron (Fe) and carbon (C) with the carbon content greater than 2 weight %. Other alloying elements may be added to enhance mechanical properties or ease processing. Cast iron is used in engine blocks as it is much cheaper and easier to .
Weichai foundries produce castings in gray iron, nodular iron, cast steel, aluminum diecast and copper for the engine and heavy industrial markets. The foundries feature advanced measurement and process equipment and are capable of producing high quality, high volume complex structures with thin wall thickness, multi level cores and high strength.
Jan 23, 2009· Cylinder Wall Thickness Technical forums. don't know the English word, but the values you found are those of the "camicia" (see attachment) for a quite average (and 20 years old) engine, like the old BMW 4 cylinders of the E36 for example, or even of an E30, can't remember.
Some other examples of tendencies in OEMs from Europe: • Audi: manufactures 2,8 million engines per year; 85% cast iron and 15% aluminum alloys engine blocks. The forecast according to this company is that direct injection diesel engines will be made from gray iron, and in near future, from CGI.
