碩士 === 大同大學 === 機械工程學系(所) === 98 === The development of internal combustion engines since mechanical actuation to high-tech devices,It have been a hundred years of experience.But the design concepts and manufacturing technologies have received Nearly complete,In order to keep improving so that help the development of diesel engines to achieve more efficient.On the materials and processing technology should be breakthroughs to enable diesel engines keep strong where reduce weight,Otherwise,It can reduce manufacturing costs and even lower-power on the losses,Also because of this,The engine development of fuel-efficient and zero emission in the future ,Still has considerable evolution of space. This paper studies how to design the engine inlet and also make good flow field of swirl.Study will focus on fluid simulation for three different inlet design by CFD analysis and measure on the flow bench with flow box,Then to do explore for the defect. Help inlet to achieve optimal performance and enhance the vortex.
