Latest Patents

Among Masaki Takeyama's latest patents are two notable inventions: the Exhaust Emission Control System and the Purification Control Device. The exhaust emission control apparatus integrates a supply device, a catalyst, and a gas pressure reduction part. It operates by supplying a reducing agent to the exhaust passage, enabling the catalyst to purify exhaust gases effectively. The gas pressure reduction component is vital as it lowers the pressure near the supply port compared to the internal pressure of the supply device body. Notably, the NOx catalyst adsorbs nitrogen oxide from the exhaust, which is subsequently desorbed when the exhaust gas is purified. Furthermore, an Engine Control Unit (ECU) estimates both the adsorption and desorption amounts of NOx, ensuring optimal performance of the system.

Another significant invention is the fuel injector designed for injecting gaseous fuel. The injector comprises a nozzle with an outlet that ensures a high flow rate of gaseous fuel, while the housing includes a mixing chamber and an air-introducing passage. This design enhances the mixing of gaseous fuel with outer air, resulting in more efficient combustion and improved fuel utilization.
