Latest Patents

One of Tomokazu Akutsu's latest patents is entitled "Controller and Control Method for Internal Combustion Engine." This innovation involves a dither control process executed on a fuel injection valve, which differentiates between a rich combustion cylinder and a lean combustion cylinder. The process operates in two modes: the first mode supports normal vehicle operation, while the second mode activates under specific conditions, such as when a temperature raising command is sent from an external device in a repair shop. The patent innovatively sets a greater difference in air-fuel ratios between the cylinders in the second mode compared to the first.

Another significant patent by Akutsu is the "Control Device and Control Method for Internal Combustion Engine." This device features an electronic control unit that carries out dither control processing in both the first and second modes. In this approach, the air-fuel ratio is managed so that one cylinder experiences a lean ratio while others operate with a rich ratio during filter regeneration requests. The second mode introduces smaller differences in the air-fuel ratios, showcasing Akutsu's ability to optimize engine performance under varying operational conditions.
