Introduction
Kuniaki Oka is a notable inventor based in Nishio, Japan. He has made significant contributions to the field of engine technology, holding a total of 6 patents. His work focuses on improving the efficiency and performance of internal combustion engines.
Latest Patents
One of Oka's latest patents is a preignition restraining device. This invention includes an ECU with an output-value obtaining portion, a preignition estimating portion, and a valve-opening-time controller. The output-value obtaining portion retrieves the output value from the knock sensor, which indicates the intensity of engine knocking. The preignition estimating portion predicts the occurrence of preignition in an internal combustion engine when the output value exceeds a specified threshold. To mitigate preignition, the exhaust-valve timing control mechanism advances the opening time of the exhaust valve. Another significant patent is a valve timing adjusting device. This device features a main lock member that fits into a main lock bore to close the intake valve at a timing later than when the piston reaches the bottom dead center. The subordinate lock mechanism further locks the rotation phase, while the lock control mechanism utilizes a temperature sensing body that changes states to control the locking mechanism effectively.
