Title: Innovations by Jeffrey S. Gutterman
Introduction
Jeffrey S. Gutterman is an accomplished inventor based in Hilton, NY (US). He holds a total of 7 patents that showcase his expertise in the field of internal combustion engine technology. His innovative contributions have significantly advanced the efficiency and reliability of engine systems.
Latest Patents
One of his latest patents is titled "Diagnostics for two-mode variable valve activation devices." This invention provides a method for detecting low-lift or zero-lift failure modes in variable valve activation systems. The process involves positioning a piezo-electric element as a radio frequency transmitter relative to a lost motion spring. By subjecting this element to a compression load, it broadcasts a radio frequency signal, which is then evaluated for its presence or absence. This direct measurement method is more reliable and efficient compared to existing diagnostic techniques.
Another notable patent is the "System for variable valvetrain actuation." This electromechanical system controls the poppet valves in an internal combustion engine's cylinder head. It allows for the variation of valve lift, duration, and phasing in a dependent manner. The design includes a rocker subassembly pivotably disposed on a control shaft, enabling changes in valve opening and closing. This system is applicable to both diesel and gasoline engines, optimizing valve timing for improved performance.
