Title: Noriaki Ejiri: Innovator in Internal Combustion Engine Control
Introduction
Noriaki Ejiri is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of internal combustion engine control, holding a total of 2 patents. His innovative approaches aim to enhance vehicle performance and reduce vibrations during operation.
Latest Patents
Ejiri's latest patents include a control method and control device for internal combustion engines. The first patent describes a control method that implements fuel cut in response to the accelerator opening degree reaching zero during vehicle travel. This method generates an antiphase torque after the fuel cut by supplying fuel to a cylinder, effectively canceling out vibrations caused by the fuel cut. The timing for generating this torque is set to occur later than during normal operation, particularly under high torque idle conditions.
The second patent focuses on a control method for engaging a lockup clutch during a fuel cut. It details a process for decreasing the lockup hydraulic pressure during fuel cut recovery, allowing the lockup clutch to engage in a slip manner. This method estimates the torque generated by the internal combustion engine during recovery, adjusting the decrease amount of hydraulic pressure based on the torque level.
