Abstract
Fuel is sequentially injected directly into each cylinder of a an engine that has at least three cylinders. Then, an ignition potential is applied to all cylinders simultaneously, but at an angle that ensures that only a selected one of the cylinders experiences combustion. This technique is repeated for each remaining cylinder, so as to fire one cylinder at a time even through an ignition potential is applied to all cylinders simultaneously.
