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
