Latest Patents

One of Nakabayashi's latest patents is a fuel supply system that features an in-tank module. This module includes a pump, a filter, a pressure regulator, and a pressure sensor that detects fuel pressure. The pressure sensor is strategically placed near the fuel pump to effectively monitor pulsation components caused by the pump. Additionally, the fuel pump controller is equipped with a speed detection module that determines the rotation speed of the fuel pump based on the pulsation cycle detected by the pressure sensor. This innovative approach allows for indirect detection of the fuel pump's rotation speed.

Another significant patent is an intake control device for internal combustion engines. This device partitions the intake path of each cylinder into upper and lower paths, incorporating a tumble control valve and an intake pressure control valve to manage airflow. By closing the tumble control valve under specific driving conditions, the intake air flow velocity in the lower path is increased, generating a tumble flow in the combustion chamber. The intake pressure control valve is opened at the start of the intake stroke and closed at its end, enhancing the difference in intake pressures and intensifying the tumble flow.
