The ignition chemical delay of kerosene with decomposed hydrogen peroxide was simulated by using n -decane as a surrogate fuel for kerosene. The influences of H 2 O 2 concentration, the H 2 O 2 decomposition rate, and pressure on the chemical delay were investigated. The ignition delay time had the negative temperature coefficient phenomenon for a low H 2 O 2 decomposition rate, and the increasing pressure weakened the negative temperature coefficient phenomenon, which nearly disappeared when the pressure was greater than 4 MPa. An R H 2 O 2 -dependent coefficient of the ignition delay time was almost not influenced by H 2 O 2 concentration and pressure when the pressure was less than 4 MPa, and R H 2 O 2 had a noticeable influence on the ignition delay time at R H 2 O 2 < 80 % . Increasing the H 2 O 2 concentration effectively reduced the ignition delay time at R H 2 O 2 < 70 % , but it had a slight effect on the ignition delay time at R H 2 O 2 > 70 % .
