Abstract
An engine having an even number of cylinders is caused to produce two differently composed exhaust gases, one rich in air and the other in unburned fuel and CO, from the two groups of cylinders each consisting of half the number of cylinders being fired in succession, which exhaust gases are fed separately to a thermal reactor and allowed to gradually mix with each other for mild and slow reaction therein.
