Title: Yoshiaki Danno: Innovator in Exhaust Gas Purification Technologies

Introduction

Yoshiaki Danno is a notable inventor based in Kyoto, Japan, recognized for his significant contributions to the field of exhaust gas purification. With a remarkable total of 42 patents to his name, Danno has demonstrated a steadfast commitment to innovation and environmental sustainability.

Latest Patents

Among Danno's latest patents is the "Exhaust Gas Purifying Apparatus." This innovative device is designed to enhance hydrocarbon purifying performance while simplifying the after-treatment process for adsorbed hydrocarbons. The system operates using a three-way valve, controlled by a controller, which enables the communication between a bypass exhaust gas passage and a main exhaust gas passage. This design allows hydrocarbons in the exhaust gas to be adsorbed onto an adsorption catalyst when the temperature of the three-way catalyst is low. As the catalyst temperature rises, the bypass exhaust passage closes, and the adsorbed hydrocarbons are oxidized into harmless substances.

Another significant invention is the "Apparatus and Method for Internal Combustion Engine Control." This apparatus aims to manage the operation of an internal combustion engine equipped with an exhaust purifying catalytic device. The system effectively absorbs nitrogen oxides during lean combustion and deoxidizes them in rich combustion modes. An electronic control unit estimates the presence of purifying capability-reducing substances and adjusts engine operations to enhance exhaust temperatures. Such innovative control helps maintain the catalytic device's effectiveness over time.
