Latest Patents

One of Hosogi's latest patents is an engine controller and engine control method. This invention includes an ignition timing control unit and a rich imbalance determining unit. The rich imbalance determining unit designates one of multiple cylinders as a subject cylinder for determination and executes lean active control, commanding a smaller amount of fuel injection for the subject cylinder than for the other cylinders. It determines whether the air-fuel ratio of the subject cylinder deviates to be richer based on a rotational fluctuation amount of a crankshaft during the execution of the lean active control. The ignition timing control unit executes an advancement limiting process that restricts the advancement of the ignition timing by the knock control during the lean active control execution.

Another notable patent is a control device and control method for an onboard engine. This control device is designed to manage the oil discharge pressure of an oil pump. It executes a change process that increases the target discharge pressure when an abnormality in the control of the oil discharge pressure is detected. If the discharge pressure sensor value does not meet the discharge pressure threshold, the control device sets an upper limit for the engine rotation speed and increases this limit as the discharge pressure sensor value rises.
