发明名称 TEST METHOD OF FUNCTIONALITY OF EXHAUST GAS RECIRCULATION VALVE OF INTERNAL COMBUSTION ENGINE
摘要 FIELD: engines and pumps.SUBSTANCE: invention relates to transport and can be used in internal combustion engines. In a test method of functionality of exhaust gas (EG) recirculation valve (13) of internal combustion engine (1), position of executive element (13a) of EG recirculation valve (13) is changed from time to time, system value (LM, LD) is measured, which is influenced by movement of executive element (13a), and a measuring signal is processed to test functionality of EG recirculation valve (13).EFFECT: improvement of diagnostic reliability of functionality of an exhaust gas recirculation valve of an internal combustion engine.6 cl, 2 dwg
