Title: Muneyoshi Nanba: Innovator in Fuel Blending Technology
Introduction
Muneyoshi Nanba is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of fuel blending technology, holding a total of 10 patents. His work focuses on improving the efficiency and control of internal combustion engines through innovative methods.
Latest Patents
One of his latest patents is a method for detecting fuel blending ratios. This method involves detecting the first blending ratio of methanol in the fuel supplied to an internal combustion engine using a blending ratio sensor. It utilizes an air/fuel ratio feedback compensation coefficient, computed based on the output of an O₂ sensor, to calculate a feedback learned value. The current blending ratio compensation coefficient is then multiplied by this value to compute the next blending ratio compensation coefficient, ensuring that the selected blending ratio is always very close to the true ratio for accurate engine control. Another notable patent is an operation control method for an engine fueled with mixed fuel. This method controls the engine's operation condition based on detection signals from a fuel blend ratio detector. In case of a malfunction in the detection, the engine is equipped with blend ratio storage for emergency blend ratios, allowing for effective ignition timing and air-fuel ratio control.
