The effect of two factors---per-chamber volume ratio (V) and injection timing (T) on the parts per million of noxious gas emitted from an engine was studied. The volume ratio was set at three equi-spaced levels and the time was set at three equi-spaced levels. Two engines were built for each of the nine treatment combinations and the amount of the gas emitted was recorded for the 18 engines as shown in the Table.
