Combustion engine comprises a cylinder head hood made from an electrically non-conducting material, an ignition coil arranged in a channel in the hood and a electromagnetic screening sleeve (10) made from a flat conducting material. An independent claim is also included for a vehicle comprising a radio receiver and the above combustion engine with the electromagnetic screening sleeve. Preferred Features: A locking device interacts with an edge of the electromagnetic screening sleeve to fix it in the channel. The electromagnetic screening sleeve has a longitudinal slot (18) with an increasing width between the upper edge and the lower edge. Die Erfindung betrifft einen Verbrennungsmotor (2) aufweisend eine Zylinderkopfhaube (4) aus einem elektrisch nicht leitenden Material und eine Zündspule (6), die in einem Zündspulenkanal (8) in der Zylinderkopfhaube (4) angeordnet ist, ferner aufweisend eine EMV-Abschirmhülse (10) aus einem blechartigen, leitenden Material, die Zündspule (6) mindestens bereichsweise umgebend in dem Zündspulenkanal (8) angeordnet ist und an elektrisch an Masse angeschlossen ist.
