A load simulation system for engine accessories

Abstract

The invention discloses a load simulation system for engine accessories. The load simulation system comprises an engine, an air compressor load simulation module, an air conditioner load simulation module, a generator load simulation module and a control unit, wherein the air compressor load simulation module comprises an air compressor, a gas storage tank and an unloading valve, the air conditioner load simulation module comprises an air conditioner compressor, a drying tank, a radiator, a condenser, an evaporator and a cooling fan, and the generator load simulation module comprises a generator and a power adjusting module. When an engine rig test is carried out, the load simulation modules can be independently or simultaneously controlled, each load simulation module can provide load varying in a certain range, and the system can be used for steplessly adjusting the size of the load, so that the universality of the system is very strong.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an engine accessory load simulation system. Background technique [0002] During the engine bench test, it is necessary to simulate the engine accessory load on the vehicle, namely the air compressor load, air conditioner load and generator load. The purpose is to better simulate the actual operating conditions of the engine so as to ensure The performance and reliability of accessories provide valid test data. [0003] Most of the existing load simulation systems for engine accessories remove the loads on the vehicle directly, and make some changes to adapt to the bench test. However, this method of transplanting accessory loads is not only time-consuming and labor-intensive in the transplanting process, but also the diversity of accessory loads makes the existing engine accessory load simulation systems less versatile. The air conditioner of other models is relatively sma...
