Title: Akira Hanari: Innovator in Combustion Diagnosis Technology

Introduction

Akira Hanari is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of internal combustion engines, holding a total of 3 patents. His work focuses on enhancing the efficiency and reliability of diesel engines through innovative diagnostic devices.

Latest Patents

One of Hanari's latest patents is a combustion diagnosis device for internal combustion engines. This device is designed for diesel engines with multiple cylinders and includes an engine speed sensor that detects the rotational speed of each cylinder. It features an injection correction amount calculation unit that calculates the necessary correction for fuel injection based on the engine speed. Additionally, a rotational fluctuation calculation unit assesses the rotational fluctuations of each cylinder, while a combustion state determination unit evaluates the combustion state of a target cylinder when the correction amount reaches a specified threshold.

Another significant patent is the exhaust throttle valve diagnosing device and method. This invention involves switching the exhaust throttle valve from a fully open position to a closed position to warm up the engine. During this process, the intake throttle valve remains fully open, and the EGR valve is kept closed. The device detects and stores the fully opened flow rate, then issues an instruction to switch the exhaust throttle valve to a closed position. It subsequently measures the engine's rotation number and determines a threshold value to assess the performance of the exhaust throttle valve.
