| 摘要 |
The invention relates to a piston of an internal combustion engine comprising an upper part ( 1 )and a lower part ( 3 )that consist of a respective light metal alloy ( 15 )and to an associated method for increasing the thermal load-bearing capacity of a multi-part piston that is subjected to high thermal stress in an internal combustion engine. The piston is provided with at least one insulating element, in particular a gap ( 7 )between the lower part ( 3 )and the upper part ( 1 ), at least one piston ring carrier ( 6 ), which consists of a different material from that of the upper part ( 1 )and the lower part ( 3 ), in particular of steel or grey cast iron, being located next to said gap as a component. A thermal current that is introduced into the piston base ( 2 )is prevented from dissipating via the piston ring carrier ( 6 )by means of the insulating element.
