Pre-Vaporized Ignition Behavior of Ethyl- and Propyl-Terminated Oxymethylene Ethers - Proceedings of the Combustion Institute Vol. 39 - P-1-P Ignition Dataset

Additional datasets are available for the other tested fuels. This data includes raw and processed time and pressure data from a dual-piston rapid compression machine for autoignition.

Test conditions were stoichiometric with 12:1 inert:oxygen, varying the gas composition to achieve the necessary pressure range. Available data include nonreactive pressure traces for comparison. Time-based variables: - t [s] - Raw and filtered pressure [Pa] - Piston position [mm] - Real and effective volume [m^3] - Gamma (fuel gamma estimated using MIT RMG group additivity methods) Summary variables: - Inert gas ratio - Average gamma - Target and actual TDC pressure [bar] - Effective compression ratio (calculated as CR required to achieve TDC pressure in isentropic compression) - TDC temperature from effective CR and from time/gamma [K] - Isentropic efficiency - Ignition delay [ms] - Gas composition
