Latest Patents

One of Nakazawa's latest patents is a recirculating exhaust gas cooling device. This device is designed to cool exhaust gas from a vehicle engine while it recirculates through an Exhaust Gas Recirculation (EGR) system, which is crucial for lowering NOx emission levels. The cooling device features a housing that contains both an exhaust gas recirculation passage and cooling fluid passages, arranged in parallel. A heat-exchange core member, which is rotatably positioned within the housing, defines multiple passages that run parallel to its rotational axis. This innovative design allows EGR gas to be cooled effectively by the cooling fluid, enhancing the overall efficiency of the engine.

Another notable patent is for a method of manufacturing a housing for a variable-volume turbocharger device. This invention includes at least two exhaust gas passages with different flow characteristics, separated by a partition wall in the turbine housing. The device features two valve members that can open and shut the exhaust gas passages in response to the engine's speed and load. This design enables the exhaust gas turbine to operate with improved efficiency, adapting to the engine's operating state.
