Multi optical probes MOP and single optical probes SOP are perfect tools for optical combustion analysis. Existing accesses can be used. For example a M8 pressure sensor access is suitable for a MOP with eight optical probes. The small SOP (diameter to combustion chamber: 2 mm) are suitable for equipping the cylinder head with a distribution over the entire combustion chamber.
The fiber optic spark plug detects light intensity signals from combustion. As shown in the diagrams. The light intensity of a single viewing sector in the radial direction, in four different applications.
