Latest Patents

Among his latest patents are two groundbreaking inventions: the "Valve operation in an internal combustion engine" and the "Spectral knock detection method and system therefor." The first patent introduces an apparatus and method for operating multiple valves in an engine. It employs valve actuators and utilizes accelerometers to monitor the valves' acceleration, detecting the moment they seat. A knock sensor identifies acoustic impulses when the valves close, and a controller correlates these signals to enhance valve actuator feedback, ensuring smoother valve operations.

The second patent presents a spectral method for knock detection in running engines. It involves acquiring spectral energy associated with vibrations caused by knocking conditions. The technology uses a sampled data system to convert accelerometer outputs into digital data samples. A knock variable is derived from spectral energy magnitudes, and a Digital Signal Processor applies a Fast Fourier Transform method to determine the knock variable. This innovative method allows for better identification of knocking conditions, thereby improving engine performance.
