摘要/Abstract

摘要： 为了研究并掌握四气门柴油机进气流动及其相互影响的变化规律,本文以热线测速原理为基础,设计了气门口流场和缸内流场的测量装置,并利用该装置在稳流气道实验台上对四气门柴油机进气门口流速分布和缸内流场进行了实际测量.

关键词: 四气门柴油机, 进气流动, 热线测速

Abstract: In order to study the intake air flow characteristics,the research designs a set of devices which can be used to measure outlet air flow field of intake ports and the intake air flow field in cylinder according to the principle of hot wire anemometer.The velocity distributions around the intake valve annulus and in cylinder are measured on a steady flow inlet port testing stand with the devices.

Key words: four valve diesel engine, induction flow, measuring velocity by hot wire anemometer
