from The Century Dictionary and Cyclopedia

  • n. The action of the burner of an explosive mixture, usually of gas and air, by which the flame runs back through the mixing- or combining-tube to the jet which delivers the fuel: due to the fact that the flow in the mixing-tube is slower than the rate at which the flame travels in such a mixture.
  • n. The pre-ignition of a mixture of gas and air, in the cylinder of an internal-combustion motor, by which the piston is strongly driven backward and a partial rotation of the shaft in reverse direction results: due to a very combustible mixture with high compression in relation to its composition, or to advanced spark-adjustment. See ignition, 5, and internal-combustion motor.
