The Preknock Kinetics of Ethane in a Spark Ignition Engine 690518

This paper tells how a model describing the chemical reactions occurring in the fuel-air mixture prior to the arrival of flame in an engine was constructed and the energy equation, including the rates of reaction as predicted by this model, integrated over the fuel-air mixture history. The kinetic model predicted sudden oxidation of the fuel in times of the order of magnitude of knock experimentally observed using ethane in a CFR engine.
