  • Internal combustion engine component and method for the production thereof
    Patent number: 7770291
    Abstract: Disclosed is an internal combustion engine component (1) which is made of an aluminum alloy and comprises at least one area (2) that is subjected to a great thermal load during operation of the internal combustion engine. Said area (2) that is subjected to a great thermal load is small compared to the entire component (1) and is provided with an alloy composition which is modified in relation to the entire component (1) in such a way that the area (2) that is subjected to a great thermal load has a greater breaking elongation than the entire component (1).
    Type: Grant

  • Internal combustion engine component and method for the production thereof
    Publication number: 20070089812
    Abstract: Disclosed is an internal combustion engine component (1) comprising at least one area (4) that is subject to a greater thermal load then another area (5) during operation of the internal combustion engine. The area (4) that is subjected to a greater thermal load is provided with a lower heat expansion coefficient (?2) then the area (5) which is subject to a lower thermal load.
