Abstract
Abstract It is common knowledge that diesel engines are frequently used in agricultural processes. Uprating a diesel engine by means of turbocharging is widely used nowadays. Turbocharging easily enables the increase in the power of the engine by 10-50%. However, the turbine creating a high effectiveness of a diesel engine became an essential problem connected with the reduction of reliability of farming machinery. One of the vital issues here refers to surge phenomena in a turbocharger. Thus, in routine maintenance of turbocharged engines the stochasticity of load leads to the changes in the geometry of the pump and turbine wheels of a turbocharger. The complex work to improve the construction of the turbocharger test bench was connected with re-creating the real operational modes of a turbocharger (TCR) on the bench and studying the limits of a surge during tests.
