An ignition system for a smoking machine is disclosed. The ignition system comprises an ignition head (12) for igniting one end of a smoking article which is held by a smoking machine, a sensor (18, 20) for detecting a distance between the end of the smoking article and the ignition head (12) in a direction parallel to the axis of the smoking article, and control means (21) for automatically adjusting ignition conditions in dependence on the detected distance. The sensor (18, 20) is arranged to detect said distance across a range of offset positions of the end of the smoking article in a plane perpendicular to the axis of the smoking article, which range is greater than the width of the end of the smoking article. |
