  "textContent": "A device may include a memory storing instructions and a processor configured to execute the instructions to obtain a motor octane number for a sample; perform a combustion test for the sample in a constant volume combustion chamber; and record, at time points during the combustion test, pressure values associated with the sample. The processor may be further configured to calculate values for one or more pressure parameters for the sample based on the pressure values; generate a motor octane number function for the constant volume combustion chamber based on the determined motor octane number and the calculated values for the one or more pressure parameters; and use the generated motor octane number function to determine motor octane numbers for samples using the constant volume combustion chamber.",
