ABSTRACT:
A sensing device for use in an internal combustion engine to sense combustion of fuel in a combustion chamber of the engine includes a tubular body part in which is located a radiation conductive element one end of which is exposed to the combustion chamber in use. On the other end of the element is a sensor which in use is connected in an electrical circuit. The sensor is responsive to radiation transmitted along the element from the flame in the combustion chamber. The element is held in a bore of the body part by a visco-elastic lining which also provides a gas tight seal and acts to cushion the element against vibration.
