On May 26th, the 72nd Society of Automotive Engineers of Japan (JSAE) Award Ceremony was held at the Pacifico Yokohama Conference Center. Our company received the "Paper Award" for our paper "Method for Estimating Knocking Sound and In-Cylinder Pressure from Engine Radiation Sound Using Deep Learning (Parts 1-3)" and was presented with a commemorative plaque.
The "Society of Automotive Engineers of Japan Award" was established in 1951 with the aim of encouraging the improvement and development of automotive engineering and automotive technology, and is awarded for significant contributions and achievements in automotive technology. The "Paper Award" is awarded to individuals and co-authors who have published papers that contribute to the development of automotive engineering or automotive technology in the past three years.
Mr. Shigeki Terashi, the 31st President of the Society of Automotive Engineers of Japan, offered his congratulations, saying, "I hope that all of you award recipients will continue to dedicate yourselves to further research and development and contribute to the advancement of automotive technology."
Award recipients
A method for estimating knocking noise and in-cylinder pressure from engine radiated noise using deep learning (Parts 1-3)
Reason for award
The sound emitted from the surface of an internal combustion engine (hereinafter referred to as radiated sound) consists of both mechanical vibrations of the engine's constituent structures during operation and combustion noise. In this paper, we demonstrate that knocking noise can be separated from engine radiated sound by measuring engine radiated sound with a microphone and generating a filter that separates sound from mechanical vibrations and combustion noise from the pectrogram of the radiated sound (a two-dimensional map representing the sound pressure intensity at each time frequency) using a Deep Neural Network.
This technological development makes it possible to detect knocking from radiated sound and evaluate the magnitude of the knocking sound without installing an in-cylinder pressure sensor in the engine combustion chamber. This technology is highly valued as it contributes to reducing the man-hours required for engine ignition timing compatibility testing, as well as improving fuel efficiency and reducing noise.
