✦ Synopsis

The hydroperoxide formed during the oxidation of n-heptane in a motored CFR engine and in a flow system has been 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.

During the oxidation of n-butane in a flow system and also in a motored CFR engine (600 rpm) hydrogen peroxide, primary and secondary butylhydroperoxides, and peracetic acid are formed. In the CFR engine these peroxides appear only when the compression ratio is larger than 10:1 (Tmu = 650 K). No aut
