In order to study the intake air flow characteristics in four-valve diesel engines, in this dissertation hot-wire anemometer and PIV twodimension instantaneous measuring technique are used. Extensive experimental study on two intake valve exit flow fields and longitudinal section flow field in cylinder are performed for different type of diesel engines. Great researching progress have been made on the interaction between two intake ports, and the formation process of in-cylinder swirl and flow field structure of cross and longitudinal section for four valve diesel engines. These results are presented in China for the first time and without such kind of research work reported abroad as detailed and deepgoing as this dissertation. The author designs and makes a set of hot wire measuring velocity device to measure the velocity distribution around the intake valve annulus and the cross section flow field in cylinder.
