Latest Patents

Sangjae Park holds a patent for an "Engine control system provided with dual continuously variable valve duration device and method of GPF forcible regeneration using the same." This advanced engine control system incorporates a dual continuously variable valve duration (CVVD) device designed to optimize engine performance. The system features an engine with a combustion chamber, an intake valve for supplying an air-fuel mixture, an ignition plug for combustion, and an exhaust valve for expelling exhaust gases. The CVVD device is responsible for adjusting the durations of both the intake and exhaust valves. Additionally, a turbine positioned downstream of the engine increases exhaust pressure, followed by a warm-up catalyst that preheats the exhaust gas, and a gasoline particulate filter (GPF) that filters soot. The controller, which operates based on vehicle driving conditions, adjusts ignition timing and the durations of the intake and exhaust valves. When lambda (λ) is 1, the controller manages the exhaust duration to prevent overlap with the intake valve timing by retarding the exhaust valve opening and advancing the exhaust valve closing. This process maintains a negative valve overlap period, thereby enhancing GPF regeneration and emissions control.
