Title: Kenji Koeda: Innovator in Emission Control Systems
Introduction
Kenji Koeda is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of emission control systems, holding a total of 3 patents. His work focuses on improving the efficiency and effectiveness of fuel vapor management in automobiles.
Latest Patents
One of his latest patents is an evaporative emission control system. This apparatus is designed to prevent the emission of fuel vapor generated in a fuel tank during fuel supply. It includes a fuel supplying canister that absorbs fuel vapor and desorbs it through an intake air flow when the internal combustion engine operates. The canister features a tank port connected to the fuel tank, a purge port linked to the air intake passage, and an atmospheric air port that introduces air. A switching device controls the cross-sectional area of the atmospheric air passage, optimizing the desorption of fuel vapor without degrading fuel supply efficiency.
Another significant patent is a canister for adsorbing evaporated fuel in automobiles. This canister is engineered to minimize the leakage of evaporated fuel, especially when the temperature rises or when it is left unused for extended periods. It consists of three integrally formed containers, each filled with adsorbents that work together to collect liquid-phase components of evaporated fuel. This innovative design extends the lifespan of the adsorbent and prevents evaporated fuel from being discharged into the atmosphere.
