This paper reports on the hydroperoxide formed during the oxidation of n-heptane in a motored CFR engine and in a flow system identified as a heptyl- ketohydroperoxide. This compound, probably the branching agent in the oxidation chain reaction, is responsible for autoignition in a CFR engine supplied with air n-heptane mixture.
