Latest Patents

One of his latest inventions is an air-fuel ratio control device. This device is designed to control the air-fuel ratio of an engine effectively. It features an exhaust passage with a main catalytic converter and a bypass passage that includes a bypass catalytic converter. The bypass passage diverges from the exhaust passage at an upstream junction and rejoins it at a downstream junction. A valve mechanism located in the exhaust passage moves between a closed and an open state. During a specific time after the valve opens, the air-fuel ratio is controlled based on a signal from a first air-fuel ratio sensor in the bypass passage, utilizing a low response correction value.

Another significant patent is a control system for hybrid vehicles. This system includes an engine, a motor capable of driving the engine, and an oil pump that supplies lubricant oil to the engine's lubrication-requiring portions. The engine lubrication controller performs operations when the engine is in a stop state for a certain period. It supplies lubricant oil to the engine and rotates it using the motor without igniting the engine, thereby ensuring proper lubrication.
