Latest Patents: Seok Won Cho holds a patent for a "Method of predicting occurrence of engine knocking." This patent outlines a sophisticated process consisting of several steps. Firstly, it begins with calculating the initial pressure in the engine cylinder based on operating data and the pressure in the intake manifold, measured by a manifold absolute pressure sensor. Following this, the method interprets the compression process as a polytropic process to determine the pressure at spark timing. Further calculations lead to the heat release rate under various operating conditions, which is crucial for understanding engine dynamics. The process continues by assessing pressure changes in the cylinder and calculating the unburned gas temperature during an adiabatic compression process. Ultimately, the method determines the occurrence of engine knocking by evaluating ignition delay and the unburned gas mass fraction.
