The reason is shown to improve the cylinder head working ability, by the increase of the alloyed silumin heat resistance. Selection of alloyed elements depends on coefficients of their diffusion in aluminium alloys. In order to increase the silumin heat resistance their alloying is recommended, using copper, nickel, magnesium, manganese. Practical recommendations are offered of how to use a number of both national and foreign heat resistant aluminium alloys as construction materials for diesel engine thermal stressed details.
