Although the vast majority of automobile engines rotate clockwise as viewed from the front, some engines are designed by the manufacturer to rotate counter-clockwise to accommodate certain mechanical configurations. In these applications, the firing order is shown in a reverse order (though it still starts with 1). For the most common inline configurations, this gives firing orders of 1-3-2, 1-2-4-3, and 1-4-2-6-3-5. In addition to the reconfiguration of the plug wires or injector tubes, the valve timing must be accordingly modified.

Famous quotes containing the words firing, orders and/or engine:
“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)
“Our own physical body possesses a wisdom which we who inhabit the body lack. We give it orders which make no sense.”
—Henry Miller (1891–1980)
“The will is never free—it is always attached to an object, a purpose. It is simply the engine in the car—it can’t steer.”
—Joyce Cary (1888–1957)
