摘　　要：为考察可调涡轮增压器对柴油机低速扭矩特性的影响,将所研制的VGT-70A型转叶式可调涡轮增压器与J6110Z型柴油机匹配进行了性能试验。介绍了试验设备和试验方法。试验结果表明,VGT-70A型增压器具有在全工况范围内与柴油机良好匹配的潜力,特别是在提高低速扭矩储备方面有明显效果。The matching work and performance test are conducted for a developed .adjustable angle rotary blade type turbocharger Model VGT-70A and Diesel engine Model J6110Z,in order to survey the effect of adjustable turbocharger on low speed torque characteristic of Diesel engine. This paper presents the test equipment and test method, it is shown by the test result that the turbocharger Model VGT-70A has a better potential in matching with the Diesel engine under all working conditions,specially for improving the low speed torque reservation.
