Problems solved by technology

[0003] The high-altitude environmental simulation laboratory system is complex and has high technical content. At present, most of the imported system equipment is imported from abroad. Due to the huge investment cost, the plateau environmental simulation laboratory that has been built in China is limited to the simulation of the diesel engine intake and exhaust system. The entire diesel engine is placed in a warehouse in a plateau environment
Although such a plateau environment simulation laboratory has achieved the purpose of plateau environment simulation, it is different from the actual plateau environment after all, and cannot fully and comprehensively evaluate the plateau environment adaptability of diesel engines. Therefore, the plateau environment simulation diesel engine test has been produced. System design technology to improve the laboratory equipment conditions that only have the ability to simulate intake and exhaust plateaus, and realize real plateau field simulation tests of diesel engines

Abstract

The invention provides a diesel engine crankcase and lubricating oil temperature control circulation integrated plateau air pressure simulation device which comprises a vacuum pump, a gas surge tank, a lubricating oil tank, a tubular heat exchanger, an electric three-way valve, a gear oil pump, an oil filter, an electric control valve, a water filter, a connecting pipeline, a temperature and pressure monitoring sensor and the like. The components are connected through a pipeline to form an integrated device, and the device not only can meet the requirements of circulating supply and temperature control of lubricating oil of the diesel engine, but also can be communicated with a diesel engine respirator. The exhaust port of the diesel engine respirator and the diesel engine lubrication circulation system are in a negative pressure state through air exhaust, air supplement and pressure stabilization control, so that plateau air pressure simulation is carried out.

Description

technical field [0001] The invention belongs to the technical field of diesel engine plateau environment simulation test, which is used in a test system of a diesel engine plateau environment simulation laboratory to detect a diesel engine plateau environment simulation test, and specifically relates to a diesel engine crankcase and lubricating oil temperature control circulation integrated plateau air pressure simulation device. Background technique [0002] As a vehicle power diesel engine, in order to meet the working needs of different regions and different environments, it is necessary to improve the environmental adaptability of the diesel engine, especially the adaptability to high altitude areas. In order to enhance and improve the adaptability of diesel engines to high-altitude environments, internal combustion engine R&D companies or manufacturers spend a lot of energy and financial resources on the verification of high-altitude adaptability of diesel engines. , t...
