The firing order is the sequence of power delivery of each cylinder in a multi-cylinder reciprocating engine.
This is achieved by sparking of the spark plugs in a gasoline engine in the correct order, or by the sequence of fuel injection in a Diesel engine. When designing an engine, choosing an appropriate firing order is critical to minimizing vibration, to improve engine balance and achieving smooth running, for long engine fatigue life and user comfort, and heavily influences crankshaft design.

Famous quotes containing the words firing and/or order:
“The sight of a planet through a telescope is worth all the course on astronomy; the shock of the electric spark in the elbow, outvalues all the theories; the taste of the nitrous oxide, the firing of an artificial volcano, are better than volumes of chemistry.”
—Ralph Waldo Emerson (1803–1882)
“What an infernal set of fools those schoolmarms must be! Well, if in order to please men they wish to live on air, let them. The sooner the present generation of women dies out, the better. We have idiots enough in the world now without such women propagating any more.”
—Elizabeth Cady Stanton (1815–1902)
