Latest Patents

One of his latest patents is the "Secondary air injection diagnostic system using pressure feedback." This diagnostic system is designed to identify failures in a secondary air injection system, which plays a vital role in reducing vehicle emissions. The system includes a pump that delivers air to the exhaust system and a valve that regulates air flow. A pressure sensor measures the pressure in the conduit, while a controller predicts the pressure during various operational phases. By comparing measured and predicted pressures, the system evaluates the operation of the secondary air injection system effectively.

Another significant patent is the "Method for on-board diagnosis of cold start emissions reduction control strategy." This method utilizes engine speed and ignition timing to verify the effectiveness of cold start emissions reduction in vehicles with internal combustion engines. It calculates thermal energy flow and assesses the system's performance based on several measured engine parameters. The diagnostic control ensures that the emissions reduction strategy operates correctly, contributing to cleaner air.
