Abstract

The invention relates to a device for a start and stop impact test of turbochargers, and belongs to the technical field of power machinery. The device comprises a first loop, a second loop and an intermediate connecting valve 17, and the turbochargers and combustion chambers in the two loops are completely same. The invention further discloses a testing method for start and stop impact of the turbochargers, and a basis is supplied to the reliability of turbine start and stop impact. The device for the start and stop impact test of the turbochargers is scientific and reasonable in test table scheme, easy to achieve, stable and reliable and has the important application value for improving the reliability of the turbochargers.

Description

technical field [0001] The invention relates to a device for the start-stop impact test of a turbocharger, which belongs to the technical field of power machinery. Background technique [0002] In the development of internal combustion engines, the application of turbocharging technology has played an important role in improving the specific power and fuel economy of internal combustion engines, reducing emissions, etc., and is known as an important milestone in the history of internal combustion engines. With the wide application of superchargers on internal combustion engines, there are more and more failures and damages of the entire engine caused by supercharger failures. At present, the reliability tests for turbochargers mainly include supercharger 120h durability thermal cycle assessment test, Hot and cold shock test, and high and low cycle fatigue test, etc. [0003] In order to solve the problem of fuel consumption of automobiles at idling speed, new energy-saving ...
