Abstract

An ignition system monitoring assembly for use in a combustion engine is disclosed. The assembly includes an igniter having at least one positioning guide with at least one transmittal member being maintained in a preferred orientation by one of the positioning guides. The transmittal member is in optical communication with a corresponding target region, and optical information about the target region is conveyed to the reception member via the transmittal member. The device allows real-time observation of optical characteristics of the target region. The target region may be the spark gap between the igniter electrodes, or other predetermined locations in optical communication with the transmittal member. The reception member may send an output signal to a processing member which, in turn, may produce a response to the output signal.

Dependent claims

A spark gap monitoring assembly for use in a combustion engine comprising:

an igniter having a first electrode and a second electrode, said second electrode being spaced apart form said first electrode by a spark gap;
at least one positioning guide associated with said igniter;
at least one transmittal member having a first portion and a second portion in optical communication therewith, said transmittal member being maintained in a preferred orientation by at least one of said at least one positioning guides, said preferred orientation placing said transmittal member first portion in optical communication with a spark gap;
and
a reception member in optical communication with said transmittal member second portion, said reception member thereby being in optical communication with said spark gap via said transmittal member,
whereby said reception member is in optical communication with said spark gap, thereby permitting real-time observation of the existence of a spark within said spark gap.
