Embodiment Construction

[0028] The preferred specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0029] An engine low pressure simulation test platform, such as figure 1 As shown, it includes a closed box body 1 made of pressure-resistant special steel, and its maximum compressive strength is at least 50 tons / square meter. The box body 1 is provided with an air conditioning unit 2 , an exhaust fan unit 3 and an engine cooling device 12 . The housing 1 is provided with a dynamometer 9 , a dynamometer cooling device 8 and an oil supply device 11 for supplying oil to the engine 10 . In order to ensure the airtightness of the box body 1, the connections between the air conditioning unit 2 and the exhaust fan unit 3 and the box body 1 are sealed connections. The air pressure adjustment range of the exhaust ...

Abstract

The invention discloses an engine low-pressure simulation testing platform. The engine low-pressure simulation testing platform comprises an airtight case body. A temperature adjusting device, an air pressure adjusting device, and an engine cooling device are disposed on the case body. A dynamometer, a dynamometer cooling device, and an engine oil supplying device are disposed in the case body. The engine low-pressure simulation testing platform is capable of simulating a low-atmospheric-pressure environment of a plateau at a low-altitude area and provides convenience for engine test.

Description

technical field [0001] The invention relates to an engine performance test platform, in particular to an engine performance test platform capable of simulating a low-pressure atmospheric environment. Background technique [0002] Common car engines use diesel or gasoline as fuel. Due to the low air pressure and low oxygen content on the plateau, for example, the atmospheric pressure in Golmud, Qinghai is almost half of that in Yulin, Guangxi. difference. Vehicles equipped with ordinary engines work normally in low-altitude areas, but once they reach plateaus, they are easy to break down, because the air on plateaus has low atmospheric pressure and low oxygen content, and the fuel cannot be fully combusted in the engine and cannot output enough power. power. In order for the engine to work normally on the plateau, it is necessary to adjust the intake air volume, oil volume and other parameters of the engine under low pressure. It is a very suitable way to transport the en...
