With a trustworthy computer model of combustion, engineers can design improved engines or fuel blends without needing to build and test so many different versions. The database of chemical reactions needed for such a computer program is too big to be filled in strictly with measured numbers, and we have to rely on chemical rate theory to calculate much of this database. Our experiments are important for showing how far we should trust these calculations.

The 'slicing' is a key new feature of this method. By using a fast shutter on the ion detector, we can wait until the middle of the ion cloud reaches the detector before we pulse the shutter on and off again. This way, we are looking only at the molecules that originally were moving parallel to the plane of the detector. That makes the images sharper and more accurate.
