Title: The Innovative Contributions of Osamu Nako
Introduction
Osamu Nako is a notable inventor based in Okazaki, Japan. He has made significant contributions to the field of automotive technology, particularly in fuel injection systems. With a total of 3 patents to his name, Nako's work has had a considerable impact on engine performance and efficiency.
Latest Patents
One of Nako's latest patents is a fuel injection device for an internal combustion engine. This device features two distinct acceleration state determining means, which include a rapid and a slow acceleration state judgement means. The rapid acceleration state judgement detects rapid acceleration by comparing the increment of the throttle opening degree with a first threshold level. Conversely, the slow acceleration judgement detects slow acceleration by comparing the increment of the throttle opening degree signal over two successive periods of the same A/D conversion timing signal. This innovative approach allows for asynchronous augmentation of fuel based on the detected acceleration state.
Another significant patent by Nako is also a fuel injection device for an automotive spark ignition internal combustion engine equipped with a supercharger. In this invention, the amount of fuel injected is determined based on the intake air pressure. The increment of the air pressure data is compared with a first threshold level to determine the first augmentation. The pressure data is averaged over each fuel injection period, and the increment of the averaged pressure data is compared with a second threshold level to determine the second augmentation. This method enhances the engine's performance by calculating the total amount of fuel injected based on the engine's supercharged state.
