Calibrition Experiment Research On The Electronic Control 4G94 D4 Type Gasoline Engine

Along with environmental pollution and energy crisis worse and worse, People establish the more strict regulation on the efficiency of gasoline engine, the standard of emission pollution, and the reliability of operation.From the March 1,2008, Beijing Municipal official government declared that the vehicle in Beijing must satisfy the chinese emission standard IV, otherwise vehicle can't be sold in Beijing. Other cities also will implement this standard gradually. Because of the emission standard changed from Euroâ…¢to Euroâ…£, the gasoline engine has to use electronic ignition system and make a abortive calibration.The paper studies on gasline engine of 4G94 D4, and analyzed the structure of engine and UAES electronic control system, and has more engine performance test on match UAES control system. The test has a large of test data and set up the model of clectronic control system, the final model and the basis of preliminary data are validated on test-bench.The successful match of 4G94 D4 engine improves, the power performance, the fuel consumption and the exhaust emission. It makes the 4G94 D4 engine to satisfy Euroâ…£emission standard, so the 4G94 D4 engine has the better competitive ability and enhance more market share and for company..
