Embodiment Construction

[0030] According to the present invention as figure 1 The piston engine high-altitude simulation test system of the embodiment of the present invention shown comprises: engine test bench 4, engine intake air temperature control system 1, engine intake air humidification system 2, engine intake air pressure control system 3, engine exhaust cooling device 5. Engine exhaust vacuum system 6, and other valves, pipe fittings, connectors, sensors, etc. (parts not shown).

[0031] Such as figure 2 As shown, in the engine air intake temperature control system 1, the temperature control of the engine air intake is fast and accurate through the mixing of the air cooling circuit 101 and the air cooling bypass 107 and the electric heater 110 and its power regulator 109 Regulates engine intake air temperature. According to a specific embodiment of the present invention, in the engine air intake temperature control system 1, clean and dry compressed air (0.8-1.0Mpa) from an air source (no...

Abstract

The invention relates to a high-altitude simulation testing system for a piston engine. The high-altitude simulation testing system is characterized by comprising an engine test bed (4), an engine air intake temperature control system (1), an engine air intake humidification system (2), an engine air intake pressure control system (3), an engine exhaust cooling device (5) and an engine exhaust vacuum-pumping system (6). The high-altitude simulation testing system provided by the invention can effectively complete the testing of various working conditions of an engine in any combined environment of the three parameters (pressure, temperature and humidity) on the ground and the high-altitude environment with low temperature and low air pressure. Compared with the traditional cabin vacuum-pumping or wind tunnel testing system, the high-altitude simulation testing system provided by the invention has the advantages of simple and reliable system, small investment, low energy consumption, low operation and maintenance cost, multiple functions and the like, and can accurately control the air intake temperature of the engine.

Description

technical field [0001] The invention relates to a high-altitude simulation test system for a piston engine, which belongs to the technical field of environment simulation. Background technique [0002] In the prior art, the test under the high-altitude simulation environment of the (aviation) piston engine is generally carried out by placing the whole engine and its accessories in a closed and vacuumed cabin or a wind tunnel. Chill to desired temperature. The disadvantages of this test system are that the system is complex, the energy consumption is high, the test cost is expensive, the preparation time before the test starts is long, and the engine intake temperature control is difficult. Contents of the invention [0003] Aiming at the above-mentioned defects of the prior art, the present invention proposes an economical and practical high-altitude simulation test system for piston engines. It can better simulate the environment where the engine works at high altitude....
