His work focuses on improving the efficiency and effectiveness of reducing agent supply devices and exhaust emission control systems for internal combustion engines.

Latest Patents

One of Suyama's latest patents is a reducing agent supply device. This device includes a tank, an adding valve, a pump, and an electronic control unit. The adding valve is designed to receive the reducing agent from the tank and inject it as needed. The pump facilitates the movement of the reducing agent from the tank and can also suction it back into the tank. The electronic control unit plays a crucial role by opening the adding valve and managing the suction of the reducing agent during purge control when the internal combustion engine is commanded to stop. It is programmed to increase the amount of return suction of the reducing agent as the amount remaining in the supply path and the adding valve increases upon receiving a stop command.

Another significant patent by Suyama is an exhaust emission control apparatus for on-board internal combustion engines. This invention includes a controller that calculates the period travel distance of a vehicle from the time the available travel distance is calculated until the next calculation. When the remaining amount of urea aqueous solution in the tank exceeds a predetermined level, the controller executes a first calculation process to determine the available travel distance based on the remaining urea solution. Once the remaining amount falls below a certain threshold, a second calculation process is initiated, which subtracts the period travel distance from the previously calculated available travel distance.
