Latest Patents

One of Masaei Nozawa's latest patents is an engine control system that includes means for learning the characteristics of individual fuel injectors. This system utilizes a fuel injector for each cylinder of the engine, an air-fuel ratio sensor located in the exhaust manifold, and an electronic control unit that processes signals from various sensors. The electronic control unit manages the engine's operation by calculating air-fuel ratio deviations among cylinders and adjusting the injection amounts accordingly. This method effectively addresses injection amount errors and ensures optimal air-fuel ratios despite external disturbances.

Another notable patent is the cylinder abnormality diagnosis unit for internal combustion engines. This invention determines whether the engine is operating within a specified range. When the engine state is within this range, the air-fuel ratio of each cylinder is estimated, and deviations from a reference air-fuel ratio are computed. If these deviations exceed a predetermined threshold, an abnormality counter is incremented, leading to the diagnosis of potential issues in the engine's performance.
