Latest Patents

Watanabe's latest patents include a system for purifying exhaust gas for use in automobiles. This system is designed to prevent the external discharge of unburnt hydrocarbons until a catalyst becomes active. It features an adsorbent positioned upstream of the catalyst, along with a heat exchanger that controls the temperature of the adsorbent and promotes the catalyst's activation. This innovative approach ensures that unburnt hydrocarbons are absorbed during the initial engine start-up period, significantly reducing emissions.

Another notable patent is an apparatus for controlling internal combustion engines. This invention focuses on purifying exhaust gas emitted immediately after engine start-up. It includes a mechanism that reduces the time required to heat the catalyst converter to its activation temperature. By operating the engine with a richer air-fuel mixture initially, the preliminary catalyst can function at lower temperatures, enhancing the overall exhaust gas purification capability.
