Embodiment Construction

[0039] 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, and are not used to limit the present disclosure.

[0040] Such as figure 1 As shown, the present disclosure provides an engine simulated plateau air intake device. The engine simulated 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 an air supply system and an air outlet 6 for connecting an engine intake pipe, and the second chamber 4 is used for connecting a pressure supply device, and the stabilizer The pressure box 1 is provided with a pressure adjusting structure that can be driven by the manual operation of the operating member 30 to communicate...

Abstract

The invention relates to an engine plateau air inlet simulation device, which 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 provided with a throttle 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 capable of being driven by manual operation of an operation component to enable 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 to the first cavity to realize simulation of a plurality of different plateau air pressures in the first cavity; and through manual operation of the operation component, the pressure regulating structure is driven to precisely adjust the pressure in the first cavity, thereby 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, and in particular, to an engine simulated plateau air intake device. Background technique [0002] When a vehicle is driving in a high-altitude area, due to the low atmospheric pressure and low air density, the engine intake is significantly smaller than when driving on a plain, and the amount of fuel required for combustion is different from that of a plain. Here, in order for the engine central control unit to recognize the plateau atmospheric pressure and correct the intake air volume, the calibration needs to be adjusted accordingly to prevent the occurrence of reduced engine output power, reduced heat dissipation performance, high exhaust temperature, and reduced fuel economy performance. Engine life. For this reason, the plateau laboratory is usually used to re-adjust and test the engines suitable for plateau vehicles to fully optimize the engine performance. For this ki...
