      Abstract: Turbocharged technology of I.C engine is an effective approach for energy saving and emission reduction,and so of turbocharger efficiency is dominate factor to engine performance.While engine power rises,its fuel economy is improved and emission reduced and significant applicability achieved. The performance test system for turbocharger shall simulate the working conditions of turbocharger to carry out bench test by remote control and adjustment of auto auxiliary system.The system might perform the test with external cold air and hot air as well as auto-recycling hot air.Additionally,the system is also applicable for tests in the process of new product research and development,performance research,production test and quality comparison.International popular virtual mode,PC emulation and analysis technology are used in research,design and manufacture.On the system,emulation is carried out like economic accounting,modeling design of part,virtual assemble and analysis platform,which might enable the test system flexible and reliable with precious data.
