Study on Gas Jet Model for Engine

In order to explore the jet law of the engine exhaust,the images of the gas jet which are shot by the high speed photograph are analyzed by Image Pro6.3 software,then under the instruction of the gas jet theory and the wearing theory of engine,the analyzing results are fitted through the MATLAB software,thus it can obtain the model that can reflect the jet law of the exhaust.This model,comparing with other similar models,has the characteristics of simple calculation and high precision,which can lay a foundation for the preventive maintenance cycle according to the jet law of engine exhaust.
