Abstract
Detection of the combustion within a cylinder of an internal combustion engine by sensing the visible and/or infra-red radiation emitted on combustion by means of a quartz window in the cylinder wall or head, a fiber optic light guide and a photo-transistor. The detection may be utilized in ignition timing, or determining engine R.P.M. or cylinder misfire.
