Summary

Increased performance levels with lower emissions place greater and greater demands on the individual components of modern high-performance engines. The largest parts of an engine, the cylinder head and the engine block, do not only have to withstand thermal and mechanical stress, but must also meet weight minimization requirements. The optimal weight efficiency currently required can only be achieved by using lightweight materials. Improved manufacturing processes, enhanced high-strength alloys and new running surface concepts mean aluminium is becoming the standard building material not only for cylinder heads, but for engine blocks as well. Strict cost and time limits are being met with the consistent use of computer simulations during cylinder head and engine block development. Engineers can now utilize appropriate simulation programs at all levels in the developent, from the manufacturing process of individual components to the engine‘s operational stability...
