VALVE GUIDE FOR AN INTERNAL-COMBUSTION ENGINE |
摘要 |
A tubularly formed valve guide (1) with a bore for a metal valve shank (2) for use in an internal combustion engine comprising a sintered body of a partially stabilized zirconium oxide having a porosity of less than 3%. Even under extreme stress, e.g., in an outlet valve of a high-power engine, but in particular in the blow-off valve of an exhaust gas turbocharger, the valve guide shows a considerably reduced wear as compared to conventional valve guides. |
