Abstract (de)

Die Erfindung betrifft eine Blowby-Heizung, die ein gasführendes Rohr (90) und wenigstens ein Heizelement umfasst. Das Heizelement ist ein PTC-Heizelement (60) (Positive Temperature Coefficient), das mit dem Rohr (90) unter Verwendung eines Klebematerials verbunden ist. Das Rohr ist vorzugsweise ein Aluminiumdruckgusrohr. Als Klebematerial dient vorzugsweise Silikonkleber, es kann jedoch in einer anderen Ausgestaltung auch leitfähiger Epoxidharzkleber verwendet werden. Die Heizelemente und das Rohr können kunststoffumspritzt sein. Die Erfindung betrifft ferner einen Verbrennungsmotor mit einer solchen Blowby-Heizung. <IMAGE>
