Title: Naoto Fujimura: Innovator in Internal Combustion Engine Technology
Introduction
Naoto Fujimura is a prominent inventor based in Wako, Japan. He has made significant contributions to the field of internal combustion engine technology. With a total of 3 patents to his name, Fujimura's work focuses on enhancing engine efficiency and reducing emissions.
Latest Patents
Fujimura's latest patents include an air fuel ratio controller for internal combustion engines. This innovative controller is designed to stop the calculation of model parameters when the engine operates in a lean condition. It features an exhaust gas sensor that detects the oxygen concentration in the exhaust gas. The identifier calculates model parameters based on the sensor's output, allowing the control unit to adjust the air-fuel ratio accordingly. This mechanism helps reduce the emission of undesired substances when transitioning from lean to stoichiometric or rich operation.
Another notable patent is a control system for internal combustion engines equipped with a catalyst. This system accelerates catalyst temperature rise by increasing the intake air amount and retarding ignition timing based on engine speed. A transient control mechanism is initiated when the vehicle reaches a predetermined speed, gradually adjusting the intake air and ignition timing to optimize performance.
