Latest Patents
One of Shirasaki's latest patents is an engine control device and engine control method. This invention provides an engine control device designed to correct the output characteristics of an oxygen sensor and perform air-fuel ratio feedback control. The device includes various sensors that detect the operating state information of an engine, an oxygen sensor, and an air-fuel ratio feedback controller. This controller adjusts the amount of fuel injected into the engine based on the operating state information and the output voltage value of the oxygen sensor. The air-fuel ratio feedback controller calculates a coefficient for correcting the output voltage value and implements feedback control to optimize fuel injection.
Another notable patent is the intake air mass estimation apparatus for motorcycles. This invention sets predetermined degrees of crank angle to divide an intake stroke into multiple sections. It measures the pressure downstream of the throttle valve and the time taken for the crank angle rotation. The apparatus estimates the intake air mass flowing from upstream to downstream of the throttle valve and integrates this data for 720 degrees of crank angle rotation, thereby estimating the intake air mass needed for one combustion cycle.
