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 an integrated plateau air pressure simulation device for a diesel engine crankcase and lubricating oil temperature control cycle. Filters, electric regulating valves, water filters, as well as connecting pipes and monitoring temperature, pressure sensors, etc. The components are connected by pipelines to form an integrated device, which can not only meet the requirements of diesel engine lubricating oil circulation supply and temperature control, but also communicate with diesel engine respirator, and make diesel engine The respirator exhaust port and the diesel engine lubrication circulation system realize the negative pressure state for high altitude air pressure simulation.

Description

technical field [0001] The invention belongs to the technical field of diesel engine plateau environment simulation test technology, and is used in a diesel engine plateau environment simulation laboratory test system to perform diesel engine plateau environment simulation test detection, and specifically relates to a diesel engine crankcase and lubricating oil temperature control cycle integrated plateau pressure simulation device. Background technique [0002] In order to meet the working needs of different regions and different environments, the diesel engine as a vehicle power needs to improve the environmental adaptability of the diesel engine, especially the adaptability in high-altitude areas. In order to enhance and improve the adaptability of diesel engines in high-altitude environments, internal combustion engine R&D companies or manufacturers spend a lot of energy and financial resources to verify the plateau adaptability of diesel engines. At the same time, in or...
