SIP革新的燃焼技術〜制御チームの研究内容と成果

抄録

The control team was divided into three groups: control group, CAE group, and PM group. The goal addressed by this team is the development of modeling and control techniques that contribute to 50% thermal efficiency. When implementing the new combustion method, there is a possibility that the performance can’t be achieved due to the influence of the disturbance, etc., and an intelligent control system that can be controlled in real time is needed. The control group developed "Model Based Control" based on a mathematical model that represents the underlying physical and chemical phenomena as closely as possible for diesel engines with advanced combustion technology. On the other hand, the CAE group developed a next-generation 3D engine combustion software "HINOCA" capable of high-speed calculation by integrating various sub-models and platforms for gasoline engines. Furthermore, the PM group developed a technology that can predict the amount of PM generation in exhaust gas generated from a gasoline engine at cold start, and developed the state-of-the-art measurement technology and proposed PM generation mechanism. Based on these fundamental studies, PM model was completed.
