ABSTRACT:
A device preheats a fuel mixture in an intake manifold of a combustion engine, the device corresponding a cylindrical body having a side wall and a bottom disposed in the wall of the intake manifold. The body is arranged on an electro- and heat insulating contact bearer and is secured on the intake manifold in an electro- and heat conducting way, the bottom of the body being provided with PTC pills which are connected to a current conductor and are secured on the bottom in an electro- and heat conducting way. The bottom has such a thickness and shape that during preheating the fuel mixture a homogeneous heat conduction is created, the side wall of the body having securing means to secure the preheater, and wherein it has such a thickness that together with the securing means it provides the required heat resistance upon heat transfer from and to the intake manifold.
