Title: Innovations of Julian D John
Introduction
Julian D John is an accomplished inventor based in Oakland, MI (US). He has made significant contributions to the field of engine diagnostics, particularly in variable valve lift systems. His innovative approach has led to the development of a patented technology that enhances engine performance and reliability.
Latest Patents
Julian D John holds a patent for "Variable valve lift diagnostic techniques based on camshaft speed." This invention provides an engine system and method for diagnosing variable valve lift (VVL) techniques. The process involves receiving a camshaft position signal that indicates the detected edges of teeth on a camshaft toothed member. This member is coupled to the camshaft of an engine, which actuates the VVL system to control the lift of the engine's valves. The controller calculates a camshaft speed signal based on the camshaft position signal and subsequently computes a valve stuck index (VSI) value. This value is used to determine if the valve is stuck by comparing it to a predetermined threshold.
