Abstract
Under the knocking condition, luminous emission from the autoignition portion in actual S.I. engine is observed using optical fibers. The difference in emission intensity between the knocking and no-knocking conditions is mainly caused by the intensities of OH and C2 radical emission. The emission intensity from these two species increases steeply at the occurrence of autoignition. In addition, emission intensity from C2 radical in some cycles has two peaks. As the first peak is due to the autoignition reaction, the second peak is understood to be caused by the soot formation in some cycles under the knocking condition. This second peak corresponded to the shadowlike object under the expansion stroke which was taken by our high-speed shadowgraphy.
