Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0021] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0022] In addition, the ...

The invention provides an engine test system, which comprises a sealed bin, a high-pressure storage bin, a flow regulating valve, a transient fuel consumption meter and a dynamometer, and is characterized in that the sealed bin is internally provided with a sealed accommodating cavity for accommodating an engine; the high-pressure storage bin is arranged in the sealed accommodating cavity and usedfor storing high-pressure gas, and the high-pressure storage bin is communicated with the engine through a pipeline; the flow regulating valve is arranged on a pipeline between the high-pressure storage bin and the engine; the transient fuel consumption meter is connected with the engine and used for measuring fuel consumption information of the engine; and the dynamometer is connected with the engine and used for measuring power information of the engine. According to the technical scheme, the air pressure, the temperature, the humidity and other conditions of the sealed bin can be adjustedto simulate different environments, and the engine collects fuel consumption information and power information of the engine through the transient fuel consumption meter and the dynamometer, so that influences of different environments on engine power can be analyzed through data and screened, the construction efficiency is improved, and the cost is reduced.
Description
technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an engine testing system. Background technique [0002] The long and long tunnels on the plateau belong to the construction of low and deep caverns. The tunnel construction process includes drilling and blasting, slag loading and dumping, vehicle transportation, mechanical excavation, and sprayed concrete. The power of the construction equipment mainly comes from internal combustion engines mainly diesel engines and air. Compressor-based motor. For diesel engines, the rapid oxidation reaction of diesel is its main energy source, but the harsh tunnel environment (high altitude, low pressure, lack of oxygen, excessive dust concentration, etc.) will lead to an increase in engine heat load and a significant decrease in thermal efficiency; As far as the press is concerned, the plateau alpine environment not only increases the heat load, but also significantly reduces the ...
