In～ cylinder gas is sampled into a vacuum chamber through an electrically actuated pulse valve mounted on an engine'head and analyzed by a quadrupole mass spectrometer. Based on the observation that the quenched volume near the cylinder wall is sampled within 1 ms from the valve open, a correction scheme extracting the reactive core component is employed. The crank-angle resolved measurement of HCCI with dimethyl ether as a fuel demonstrated that intermediate species such as aldehyde and hydrogen peroxide appear at the first stage cool ignition and disappear at the last stage hot ignition. This result is a validation to the detailed chemistry model predictions for the two-stage ignition.
