Latest Patents
Wataru Koizumi holds a patent for a method of diagnosing regeneration failure of an exhaust emission control device. This method involves the use of filter regenerating means to forcibly heat a particulate filter, allowing for the burning off of captured particulates. The process includes obtaining an exhaust flow rate to the particulate filter and measuring the differential pressure between the entry and exit sides of the filter. By calculating the gradient of change in differential pressure relative to the change in exhaust flow rate, the method can effectively diagnose regeneration failure when the calculated gradient exceeds a predetermined reference gradient. This innovation is crucial for maintaining the efficiency and effectiveness of exhaust emission control systems.
