Latest Patents
One of Nakahira's latest patents is an engine exhaust treatment device designed to efficiently combust particulate matter (PM) accumulated in a diesel particulate filter (DPF). This device is unique in its capability to activate an exhaust purification catalyst right after engine startup or during light load operations. The design incorporates a combustible gas supply passage that communicates with the exhaust passage upstream of a combustion catalyst. A control unit is linked to both an air supply unit and an ignition unit, facilitating combustion at lower exhaust temperatures. The flame combustion of the combustible gas heats the exhaust, thereby enhancing the overall exhaust treatment process.
Another notable patent involves an exhaust treatment device specifically for diesel engines, which utilizes the combustion of gas with oxygen to increase exhaust temperatures. This method effectively reduces PM accumulation within the DPF by enabling the combustion heat to burn off the particulates. The innovative design includes a heater that initiates the generation of combustible gas, strategically positioned within the catalyst inlet to optimize performance.
