Diesel engine box body simulation test bench system for simulating altitude climate of plateau and test method thereof

Abstract

A diesel engine box body simulation test bench system for simulating altitude climate of a plateau comprises a test box, an energy box and a diesel generating set; the test box comprises a test box assembly and a monitoring box assembly; the test box assembly comprises a test box body. The test box body is provided with an iron floor, a fast-assembly trolley, an air spring shock absorber, an oil-water-gas butt joint layer, an intermediate-temperature cool-heat-exchanger, an air flow meter, a dynamometer, an oil consumption meter, an air inlet pipe and an exhaust pipeline; the monitoring box assembly comprises a monitoring box body, and a control cabinet, an electric cabinet, a monitoring display screen, a seat and an emergency stop switch are arranged in the monitoring box body; and the energy box is divided into a front box body, a middle box body and a rear box body by two partition plates. The defect that other vehicle enterprise large-scale laboratory equipment cannot be moved andcannot be used for testing in other regions is overcome, and diesel engine simulation tests under various conditions of altitude climate of the plateau can be well realized.

Description

technical field [0001] The invention relates to a test bench system, in particular to a simulated test bench system and a test method for a diesel engine casing under a simulated plateau altitude climate. Background technique [0002] When vehicles, construction machinery and other power equipment operate at different altitudes, there are usually problems such as different degrees of power drop, high failure rate of product quality, and unstable operation of equipment. These problems can be attributed to the engine running at different altitudes due to Changes in altitude pressure conditions affect engine intake pressure, temperature, and humidity changes, thereby affecting engine performance, and will eventually lead to varying degrees of changes in the engine's continuous operating capability and operating intensity at different altitudes. [0003] The traditional engine performance laboratory usually adjusts the pressure in a closed laboratory, and the engine directly inh...
