Embodiment Construction

[0037] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

[0038] like figure 1 As shown, the present disclosure provides an engine simulation plateau air intake device, the engine simulation plateau air intake device includes a surge tank 1, the surge tank 1 is separated by a partition 2 to form a first chamber 3 and a second chamber 4. The first chamber 3 is formed with an air inlet 5 for connecting to an air supply system and an air outlet 6 for connecting to an engine air intake pipe. The second chamber 4 is used for connecting a pressure supply device. The pressure box 1 is provided with a pressure regulating structure for connecting or blocking the communication between the first chamber 3 and the second chamber 4 , so...

Abstract

The invention relates to an engine plateau air inlet simulation device. The engine plateau air inlet simulation device comprises a pressure stabilizing box. The pressure stabilizing box is separated by a separator plate into a first cavity and a second cavity. The first cavity has an air inlet connected with an air supply system and an air outlet connected with an engine air inlet pipe. The second cavity is used for connecting with a pressure supply device. The pressure stabilizing box is provided with a pressure regulating structure for enabling the first cavity and the second cavity to be communicated or blocked so as to adjust the pressure in the first cavity. The air supply system supplies air into the first cavity of the pressure stabilizing box through the air inlet, and the pressure regulating structure can enable the air in the first cavity to be discharged into the second cavity so as to reduce pressure in the first cavity, or enable the air in the second cavity to flow into the first cavity so as to increase the pressure in the first cavity, thereby realizing adjustment of pressure of air entering the engine air inlet pipe and achieving an effect of accurately controlling inlet pressure of an engine by simulating plateau air inlet states.

Description

technical field [0001] The present disclosure relates to the technical field of engine test equipment, in particular, to an engine simulating plateau air intake device. Background technique [0002] When the vehicle is driving at high altitudes, due to the low atmospheric pressure and low air density, the intake air volume of the engine is significantly smaller than that when driving on the plain, and the amount of fuel required for combustion is different from that on the plain. In order to allow the engine central control unit to recognize the plateau atmospheric pressure and correct the intake air volume, it needs to be adjusted and calibrated accordingly to prevent the reduction of engine output power, heat dissipation performance, high exhaust temperature, and fuel economy performance. Engine life. To this end, high-altitude test chambers are usually used to retune and test engines suitable for high-altitude vehicles to fully optimize engine performance. For this kind...
