QSX15 ISX15 DIESEL PARTS CYLINDER BLOCK FOR SALE FORD ENGINE BLOCK ALUMINIUM CYLINDER BLOCK

The cylinder-block material should

(a) be relatively cheap,

(b) readily produce castings with good impressions,

(c) be easily machined,

(d) be rigid and strong enough in both bending and torsion,

(e) have good abrasion resistance,

(f) have good corrosion resistance,

(h) have a high thermal conductivity,(to prevent failure under high temperatures).

(i) retain its strength at high operating temperatures, and

(J) have a relatively high thermal expansion, low density.(to resist expanding under high operating temperatures)

High strength is a particular concern in diesel engines, since compression ratios are normally 17.0:1 or higher compared to about 10.0:1 for conventional engines. , and thermal conductivity . Good machinability and castability of the metal alloy are also important factors in selecting the proper material, as the harder it is to machine the product, the higher the costs of manufacturing. In addition to the previously mentioned properties, the alloys must possess good vibration damping to absorb the vibrations of the moving parts.

METALS USED IN THE MANUFACTURE OF THE CYLINDER BLOCKS:

Based on the functional requirements of the cylinder block and the material properties required to meet the functional requirements, industries have used cast iron and aluminum alloys to manufacture the blocks.

EXISTING MATERIALS:

1)Cast iron alloys are used because of the combination of good mechanical properties, low cost, and availability.

2)Certain aluminum alloys combine the characteristics of iron alloys with low weight, thereby making the material more attractive to manufacturers who are seeking a competitive edge.

NEW MATERIALS:

3)Compacted graphite cast iron is lighter and stronger than gray cast iron, making the alloy a more attractive alternative to the latter in the production of cylinder blocks, particularly in diesel engines.

4)Magnesium alloys, which were previously unsuited for use as an engine block material, have the advantage of being the lightest of all the mentioned metals, yet still retains the required strength demanded by a block.
