Abstract

The invention relates to a turbocharger startup and shutdown impact test device and belongs to the power machinery technical field. The turbocharger startup and shutdown impact test device includes an air source air intake pipeline, an air changeover valve, a first branch and a second branch; two sets of turbochargers and combustion chambers in the two branches are exactly the same; and an external air source is adopted to supply air. The invention also discloses a turbocharger startup and shutdown impact test method which can provide basis for turbocharger startup and shutdown impact reliability. The test bed provided by the invention has the advantages of being scientific, reasonable, stable and reliable as well as easiness in implementation, and has an important application value in improving the reliability of the turbochargers.

Description

technical field [0001] The invention relates to a start-stop impact test device for 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 automob...
