is actually used in one firing of a spark plug?

Wow! I have never saw so many wrong answers, but they sound convincing. Here is the truth and you can take it to the bank. Remove one fuel injector, and use a container to capture the fuel. Remove all the injector harness wiring except the one you have removed the injector on to do the test. Now turn the engine over until the injector fires one time. If the injector is not clogged or having some mechanical problem, it should squirt the amount that is stamped on the injector. The computer controls the pulse width, and the amout of fuel injected by the size of the orfice in the injector. Now, if the fuel pressure is at its advertised PSI, there should be the precise amount for one firing of a cylinder in your collection jar. The real truth of the matter is, there are so many variables that one cannot determine the amount of fuel it takes. You would have to figure in the load on the engine, and everything else. The simple way to do this is put a measured amount of fuel in the tank, run the engine until it stops, and calculate from there. No two engines will burn the same amount of fuel in a given time frame. You can only do a test to determine an average for that type of engine. Besides no engine burns all the fuel in the combustion chamber, as some is expelled out the exhaust as not burned. To prove this all you have to do is install a spark plug into the exhaust pipe, and use a coil to fire it, and you will see this huge flame roll out the tail pipe.
Glad I could answer your question. Good Luck!!!

An 8:1 ratio of air to fuel. It is based on the Cylinder of the car. A Chevy 350 is 350 Cubic Inches of Bore for the piston. One/8th is fuel on each stroke. Divid 350 by 8. Use this # to compare to your Cars engine. If you have a Chevy 307 for example, 307 divided by 8= and 350 divided by 8 = Subtract the 307 8th from the 350 8th. This is your average or meen # of fuel at each spark plug. Herbert West III west.herb@yahoo.com

very little it is more like a mist of gas mixed with a bunch of air in return it gets ignited from the spark more.

Depends on displacement, temperature, altitude, load and other factors.
