ABSTRACT:
The present invention is for a new kind of sparking device. It is especially suitable for counterstroke engines in which two pistons are working against each other in a common cylinder bore. The invention is for a sparking device for combustion engines which makes it possible to change the distance between the electrodes of the sparking device both with a stopped engine and during operation. The invention also makes it possible to position the sparking device in the center of the cylinder bore and combustion space. The two electrodes are mounted separated from each other in the cylinder wall so that they are opposite to each other and have their centre axis essentially aligned with each other. A linear displacement of one of the electrodes thus means that the distance between the tips (14, 15) of the electrodes is changed.
