Latest Patents

One of his latest patents is focused on a hydraulic start-of-injection detecting system and method. This groundbreaking disclosure introduces a system that determines hydraulic start of injection (SOI) in engines by utilizing an in-cylinder pressure sensor. The method involves performing a wavelet transform iteratively on signals derived from pressure information gathered by the in-cylinder pressure sensors. This enables the determination of a detail coefficient corresponding to specific frequency bands, which are indicative of pressure pulsations caused by fuel jets injected into the engine cylinder. The innovation stands out as it effectively detects hydraulic SOI at the moment when the amplitude of the detail coefficient exceeds a pre-defined threshold. Moreover, this system provides diagnostic, control, and compensation capabilities for fuel injector functioning in high-pressure fuel rail engine systems, all without the need for expensive or intricate injector components.
