ams-professional Motorenkunde: Die schaltbare Kolbenkühlung

Der Kolben muss bei heutigen Fahrzeugmotoren zahlreichen Anforderungen standhalten, z. B. bei Pkw-Dieselmotoren Einspritzdrücke bis 2200 bar, Verbrennungsspitzendrücke bis 210 bar, spezifische Leistungen jenseits von 100 kW pro Liter Hubraum und immer geringere Abgasemissionen. Am heftigsten setzen aber die hohen Betriebstemperaturen von etwa 370 °C am Kolbenboden beim Diesel und rund 300 °C beim Ottomotor den Kolben zu.
