Latest Patents
Among John M. Clarke’s latest patents is the innovative idea of "Fuel injector spray alteration through a moveable tip sleeve." This patent discloses an apparatus and method that involves a sleeve around a fuel injector tip, which is capable of moving between two positions. This movement allows the sleeve to manipulate the fuel spray as it enters the combustion chamber, enabling different spray profiles or plumes, thereby facilitating multiple modes of fuel injection, including homogenous charge compression ignition.
Another significant patent from Clarke is related to the "Homogenous charge compression ignition engine having a cylinder including a high compression space." This invention aims to improve performance by controlling the timing of ignition within the engine. By dividing the homogeneous charge between a higher compression controlled volume and a lower compression space in the cylinder, Clarke seeks to optimize the ignition event, reducing the risks of performance issues, misfires, or potential engine damage.
