Device for fuel injection in combustion chambers of, in particular, selfigniting combustion engines with an injection nozzle (10) and a subsequently switched incandescent wire (20) which has a conduit (30) surrounded by a double heating layer (33) on the inside for passing through of the injection streams. The double heating layer (33) consists of an inner heating layer (35) which is separated from a second heating layer (37) by an electrical insulator. In the parallel as well as the series switching of the two heating layers (35,37), a two stage heating of the double heating layer (33) is possible. The inner heating layer (35) reaches the required end temperature required for ignition in a relative short time, while the second heating layer (37) assures a high energy density of the ceramic support mass (38).

Device for fuel injection in combustion chambers of, in particular, selfigniting combustion engines with an injection nozzle and a subsequently switched incandescent wire which has a conduit surrounded by heatable walls through which the injection streams of the fuel can pass through substantially unhindered, characterized in that at the side of the combustion chamber at least two superimposed heating layers (35,37) are provided and separated from each other by insulation (36) in the conduit of the incandescent wire (20).
