Development of the test data processing system of internal combustion engine

In order to study the characteristics of the internal combustion(IC) engine and evaluate the power and economic performance of the engine operating at different working conditions,the test data processing system of the IC engine is developed. The system collects data by the data file, calculates the characteristic parameters of the IC engine by the software compiled according to corresponding formulae, and draws the characteristic curves by using the curve fitting method. The practical application shows that the test data of the IC engine can be processed conveniently, quickly and exactly and the characteristic curves can be drawn clearly by using the presented system.
