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.
