Latest Patents

One of Ueno's latest patents is the "Exhaust Gas Purification Control Device." This device is designed for systems that utilize a catalyst and a supply valve for urea water. The controller performs an abnormality diagnosis of the supply valve and includes a urea water filling portion, a valve opening command portion, and an abnormality determiner. The urea water filling portion activates the pump at the start of the exhaust gas purification system to fill the supply passage with urea water. The valve opening command portion issues a command to open the valve when the urea water pressure in the supply passage exceeds a predetermined threshold. The abnormality determiner assesses whether there is a sticking issue with the supply valve based on the urea water pressure after the command is issued.

Another significant patent is the "Urea Water Supply System." This system comprises a first and a second supply valve for delivering urea water, along with a supply passage connecting a urea water tank to these valves. The electronic control unit (ECU) manages the operation by opening the first supply valve while keeping the second closed to initiate the filling process. The ECU then determines when the filling of urea water into the first supply passage is complete.
