With a total of 2 patents, Yamada's work reflects his commitment to enhancing engine performance and reducing environmental impact.

Latest Patents

Yamada's latest patents include an innovative exhaust emission control system for engines. This system features a NO catalyst that stores nitrogen oxides (NO) within exhaust gas when the air-fuel ratio is lean. It effectively reduces the stored NO when the air-fuel ratio approaches stoichiometric or rich conditions. The processor executes a NO reduction control module that allows for post-injection of fuel to maintain the air-fuel ratio at a target level, ensuring that the stored NO is reduced below a specified amount.

Another significant patent is for air supply control systems for turbocharged internal combustion engines. This system comprises first and second turbosuperchargers, along with exhaust and intake air cutoff valves. The cutoff valve controller manages these valves to optimize engine performance based on intake air mass flow. The operation controller adjusts the boundary between different operating areas on the engine's characteristic chart, enhancing efficiency during various engine loads.
