Latest Patents

One of Takashi Takatsuka's latest patents is a fault diagnosing apparatus for evapopurge systems. This apparatus includes a device designed to detect pressure within an evapopassage that encompasses a fuel tank. It features a depressurization device that closes a first valve in an atmosphere-opened port of a canister, allowing for the depressurization of the evapopassage through a negative pressure generated in the suction passage of an internal combustion engine. Additionally, a repressurization device is included, which closes a second valve after the depressurization process is complete, thereby repressurizing the interior of the evapopassage. The fault judgment device allows for the assessment of the evapopurge system's functionality based on outputs from the pressure detecting device, particularly when the depressurization and repressurization devices are operated multiple times. Another notable invention is a control device for an internal combustion engine, which further showcases his expertise in this domain.
