Latest Patents
One of his latest patents is the "Operating method of two stroke direct injected engine." This invention involves a two-cycle crankcase compression internal combustion engine, where a single fuel injector is mounted in the cylinder block. The injector can inject fuel either directly into the combustion chamber or into the induction system through the crankcase chamber via a window in the piston. The control strategy disclosed in this patent allows for injection primarily into the induction system during startup and low temperature conditions.
Another significant patent is the "Engine control system and method." This methodology measures engine combustion rate and Indicated Mean Effective Pressure (IMEP) by analyzing in-cylinder pressure at specific crank angles. It utilizes a basic reading of pressure in the combustion chamber when it is near atmospheric, as well as at least one point in time after ignition begins and before top dead center. The data collected can be used for fine-tuning engine control to achieve optimal performance.
