Latest Patents

Hiroshi Oiwa holds a patent for an EGR control device. This device includes several key components: a tumble generation valve, a recirculation passage, an EGR valve, an EGR valve opening degree deriving unit, and an EGR valve control unit. The tumble generation valve is designed to adjust the passage area of an engine's intake passage. The recirculation passage facilitates the recirculation of exhaust gas from the engine's exhaust passage back to the intake passage. The EGR valve is strategically placed on the recirculation passage to control its opening and closing. The EGR valve opening degree deriving unit calculates the opening degree of the EGR valve based on engine speed, engine load, and the opening and closing rate of the tumble generation valve. Finally, the EGR valve control unit drives and manages the EGR valve to achieve the derived opening degree.
