With a total of three patents to his name, Ploucha's work focuses on improving the efficiency and reliability of internal combustion engines.
Latest Patents
One of Ploucha's latest patents is the "Short Runner Valve Diagnostic." This method involves diagnosing the operating condition of a short runner valve in an intake manifold of an internal combustion engine. It utilizes an exhaust sensor located in the exhaust manifold to determine whether the valve is functioning correctly. The valve is commanded to an open position for a test period, and if the sensed exhaust gas parameter exceeds a predetermined threshold during this time, a pass signal is issued. Conversely, a fail signal is issued if the threshold is not met.
Another significant patent is the "Engine Warm-Up Model and Thermostat Rationality Diagnostic." This method tests a thermostat in a motor vehicle by predicting the engine coolant temperature at a specific time after start-up. It compares the predicted temperature to the actual temperature read by a sensor. The results of this comparison help determine whether the thermostat is functioning properly, categorizing the outcome as pass, fail, or inconclusive.
