With a total of two patents to his name, Imai's work focuses on enhancing the performance and efficiency of turbochargers used in internal combustion engines.

Latest Patents

One of Imai's latest patents is centered on a turbocharger design. This innovative turbine housing features a scroll part along with an outlet pipe and an inlet pipe. A unique aspect of this design is the bypass passage formed on the inner peripheral side, which leads from the inlet pipe toward the scroll part. This configuration allows communication between the inlet passage and the outlet passage, effectively optimizing airflow. Furthermore, the patent specifies the orientation of the outlet opening's center, ensuring precise placement within the mounting flange’s quadrants.

Another key patent of Imai involves a supercharging pressure control method and device for internal combustion engines. This invention introduces a turbocharger that includes a wastegate valve. The system features a first setpoint for the wastegate valve's opening that is determined by a targeted boost pressure. The patent describes a method of adjusting the valve's opening based on the gap between the target boost pressure and the actual boost pressure. This approach ensures that opening adjustments occur when specific criteria—intake air quantity and engine rotation speed—are met, thereby enhancing the overall engine performance.
