A control system for durability test of engine front end gear train accessories

Abstract

A control system for the durability test of front-end gear train accessories of an engine, including a controller, a system air-conditioning compressor, a power steering pump, a generator, an air-conditioning compressor load loading device, a power steering pump load loading device, a generator load loading device, and an ambient temperature The controller is equipped with an engine idling state monitoring unit, an air-conditioning compressor endurance test control unit signal-connected to the air-conditioning compressor load loading equipment, and a power steering pump endurance test control unit signal-connected to the power steering pump load loading equipment 1. The generator endurance test control unit connected with the generator load loading equipment signal. This design not only realizes the uniform, rapid and accurate test of the durability performance of the engine front-end wheel train accessories, but also does not need to occupy the resources of the engine bench.

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...

Problems solved by technology

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 accessories; at the same time, for the developed engine front-end gear train durability test method, there is a lack of corresponding test control system to control the operation of each accessory loading device in accordance with the durability test method; the engine bench control system is adopted Loading the front-end gear train accessories, there are problems such as long debugging period, high cost of remanufactured bench, and long time of bench resources occupied by endurance test
