Abstract
The invention relates to a corona ignition device for igniting fuel in a combustion chamber of an engine by means of a corona discharge, said corona ignition device comprising an insulator, a center electrode, which is held in the insulator, a housing, in which the insulator is held, and coil turns, which are disposed in a cylindrical main part of the housing and are connected to the center electrode. According to an aspect of this disclosure, the housing widens on the side of the main part remote from the insulator and further coil turns are disposed there, in a wider housing part.

A corona ignition device for igniting fuel in a combustion chamber of an engine by means of a corona discharge, said corona ignition device comprising:
- an insulator;
- a center electrode held in the insulator;
- a housing in which the insulator is held;
- and
- coil turns, which are disposed in a cylindrical main part of the housing and are connected to the center electrode;
- wherein the housing widens on the side of the main part remote from the insulator to form a wider housing part, further coil turns being disposed in the wider housing part, wherein the further coil turns have a greater diameter than the coil turns in the main part and the coil turns and further coil turns are connected in series.
A corona ignition device for igniting fuel in a combustion chamber of an engine by means of a corona discharge, said corona ignition device comprising:
- an insulator;
- a center electrode held in the insulator;
- and
- an elongated housing in which the insulator is arranged;
- said housing having a first portion in which a first coil is arranged and a second portion in which a second coil is arranged that is connected in series with the first coil;
- wherein, the first portion has a larger length than the second portion, the second portion is wider than the first portion, and the second coil comprises coil turns that have a larger diameter than all coil turns of the first coil.
