Title: Innovations of Amarjit S Ghuman
Introduction
Amarjit S Ghuman is a notable inventor based in Columbus, IN (US), recognized for his contributions to hydraulic systems and internal combustion engine technology. With a total of seven patents to his name, Ghuman has made significant advancements in the field of engineering.
Latest Patents
One of his latest patents is the "Dual-pressure hydraulic valve-actuation system." This innovative system and method facilitate the hydraulic actuation of poppet valves. The poppet valve is opened by applying hydraulic pressure to a piston and is closed by the action of a mechanical spring. The hydraulic pressure can originate from either a high-pressure source or a low-pressure source, with the latter being higher than ambient pressure. A pressure control device, based on signals from an electronic controller, manages the application of hydraulic pressure in a manner that minimizes the power required to actuate the valve by utilizing valve inertia.
Another significant patent is the "Early exhaust valve opening control system and method." This exhaust valve system is designed for internal combustion engines equipped with turbochargers. It effectively increases turbocharged boost pressure during low load engine conditions, thereby enhancing engine transient response. The system includes an exhaust valve control device that operates in a normal timing mode and an advanced timing mode. The advanced mode allows for the opening of the exhaust valve to occur earlier than the normal opening crank angle while maintaining the timing of normal closing.
