Abstract
In a pre-combustion or turbulence chamber for an internal combustion engine, an inner molded body, defining an inner chamber, is formed of a material having a thermal conductivity of at least 12 W/(m.multidot.K). An outer body is secured to the outer surface of the inner body by shrinking or glueing. The outer body is formed of a thermally insulating ceramic material having a thermal conductivity of less than 10 W/(m.multidot.K). Due to the low thermal conductivity of the outer molded body, the inner molded body is insulated against heat losses. The higher thermal conductivity of the inner molded body has the effect that, in the interior of the pre-combustion or turbulence chamber, the point at which the cold fuel jet impinges during the injection process is only slightly cooled.
