Latest Patents

Hiroshi Yoshida holds a patent for an engine control device designed to suppress thermal degradation of a particulate filter. This device executes a fuel injection control module that restricts the supply of fuel by an injector when a fuel cutting condition is satisfied. Additionally, it includes an accumulation estimation module that estimates the amount of soot trapped in a gasoline particulate filter (GPF). The regeneration control module performs regeneration control to burn soot when the accumulated soot amount exceeds a predetermined threshold. A fuel cut prohibition line is established to define a prohibition temperature for fuel cutting control based on the accumulated soot amount. Furthermore, the device incorporates a prohibition control module that prevents fuel cutting control if the GPF temperature exceeds the prohibition temperature. This innovative approach enhances the longevity and efficiency of engine systems.
