With a total of three patents to his name, he is recognized for his innovative approaches that enhance vehicle efficiency and reduce environmental impact.

Latest Patents

Among Kenji Katayama's latest innovations is an advanced exhaust purification system for internal combustion engines. This system features a lambda air-fuel (LAF) sensor within the exhaust pipe, generating signals that correspond to the air-fuel ratio of the exhaust gas. Positioned downstream of the LAF sensor, an upstream catalytic converter is equipped with a catalyst designed to purify the exhaust gases effectively. Further along the system, an oxygen sensor (O2 sensor) analyzes the air-fuel ratio, contributing additional signals for optimized performance. A gas particulate filter (GPF) follows the O2 sensor to capture and purify exhaust gases thoroughly. Moreover, an electronic control unit (ECU) plays a crucial role in managing the air-fuel mixture in the engine, ensuring that the exhaust gases directed to the GPF maintain a target air-fuel ratio close to the stoichiometric limit. This patented technology represents a significant leap towards cleaner automotive emissions.
