Latest Patents

One of her latest patents is an exhaust gas purification device. This device is capable of diffusing and introducing a reducing agent into a NO catalyst arranged in a downstream side exhaust gas passage. The housing of the device includes a main body that houses both upstream and downstream exhaust gas passages. A cap is attached to the main body, featuring an outlet side opening for the upstream passage and an inlet side opening for the downstream passage. The design includes a guide portion for directing the exhaust gas flow and a reducing agent diffusion portion to facilitate the mixing of the reducing agent with the exhaust gas.

Another notable patent is the exhaust gas purification apparatus for internal combustion engines. This invention provides a system that evenly diffuses a reducing agent throughout the entirety of the exhaust gas flowing into an NO catalyst. The apparatus includes an NO catalyst located in the exhaust gas passage of an internal combustion engine, along with a reducing agent injecting unit. This unit injects the reducing agent into the exhaust gas passage upstream of the NO catalyst. A narrowed portion is created downstream of the injecting position, which enhances the diffusion of the reducing agent.
