ABSTRACT:
In an internal combustion engine, large droplets of heavy fuel are injected in the combustion chamber in the presence of excess air and preferably under low pressure. The mixture of excess air and droplets of fuel is compressed and thereby forced to pass at high velocity through a vortex throat (i.e. small orifice) into an ignition chamber, where the friction between droplets and air causes self-ignition of the surface layers of the droplets. The combustion gases force the burning droplets, through the vortex throat, back into the combustion chamber under high velocity, thereby the burning surfaces of the droplets continuously come in contact with fresh supplies of air, until they burn substantially completely.
