Latest Patents

One of his latest patents is titled "Method and device for diagnosing and controlling combustion instabilities in internal combustion engines operating in or transitioning to homogeneous charge combustion ignition mode." This invention outlines a method for achieving stable and optimal mixtures of Homogeneous Charge Compression Ignition (HCCI) and Spark Ignition (SI) in practical gasoline internal combustion engines. The process involves characterizing the combustion based on measurements, determining the ratio of conventional and HCCI combustion, and modifying subsequent combustion processes to achieve desired behavior.

Another notable patent is "Combustion diagnostic for active engine feedback control." This invention detects the crank angle location where combustion transitions from premixed to diffusion, known as the transition index. It defines integration limits to measure heat released during combustion phases, leading to the development of a combustion index. This index helps in understanding the combustion process and provides feedback to engine control algorithms, particularly in low-temperature combustion modes.
