Description

technical field

[0001] The invention belongs to the field of automobile engine testing, and in particular relates to a control system for the durability test of an engine front end gear train accessory. Background technique

[0002] The gear train accessories at the front end of the automobile engine work under high engine room ambient temperature and changing workload conditions. In order to ensure the reliability of the engine front gear train accessories, durability tests are usually required. At present, during the verification process of the engine durability test, the assessment of the front-end gear train accessories lacks a corresponding targeted bench test assessment method. It is often assessed by carrying other conventional endurance tests or the durability of the whole vehicle. The durability assessment is single, the conditions are not strict, and periodic Long, unable to achieve the purpose of durability assessment and verification of front-end gear train acces...
