In this system, a device is placed inside the injectors on the manifold or inside three different design housings above the combustion chambers of engines. The device is a combine that has a cylinder that has a set of vanes. In one embodiment a small motor is used to turn the cylinder, which helps to atomize the fuel to a fine state. This atomization improves combustion in that the smaller fuel particles can burn more efficiently and more completely than larger drops of fuel that is simply squirted into a cylinder or manifold. In two other embodiments, the cylinder (combine) can be turned with a belt driven by the engine.
