Description
Technical field
The utility model engine test technical field, relates generally to a kind of high-speed internal combustion engine simulated exhaust system test dress
Put.
Background technology
Internal combustion engine is the high compression combustion chamber that cylinder interior is directly inputted after one kind mixes liquid or gaseous fuel with air
Burning outburst produces the Thermal Motor of power, and internal combustion engine often makees a work(and completes four air inlet, compression, work done and exhaust mistakes
Journey.In internal combustion engine simulated exhaust STS system test set, compressed air is after heater box heats, temperature rise, subsequently into
Cylinder work done, work done finish, and the gas discharged out of cylinder enters compensator, is then discharged by pressure regulator valve, but from cylinder
Gas temperature out is about 600 DEG C, it is easy to burns out pressure regulator valve.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose a kind of high-speed internal combustion engine simulated exhaust system examination
Experiment device.
The utility model adopts the following technical scheme that to solve above-mentioned technical problem：
A kind of high-speed internal combustion engine simulated exhaust STS system test set, the experimental rig have compensator, the pressure regulation
Tank is connected to the output terminal of cylinder；Water collar is equipped with the compensator, the water inlet of the water collar is located at compensator
The nearly port of export, water outlet are located at the nearly input end of compensator；The cooling water of the water collar on compensator is arranged on by compensator
The nearly port of export form the circulated in countercurrent opposite with the flow direction of air in compensator to input end circulation；The compensator
The port of export connects outlet pipe；Counterbalance valve is provided with the gas pipeline, and between the counterbalance valve and compensator
Pressure regulator valve is additionally provided with pipeline.
The utility model proposes a kind of high-speed internal combustion engine simulated exhaust STS system test set, adverse current is provided with compensator
The water cooling plant of recirculated cooling water, can effectively reduce the temperature of the high-temperature gas come out from cylinder, protect pressure regulator valve not to be burned,
Guarantee test is smoothed out.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
In figure：1st, cylinder, 2, water collar, 3, compensator, 4, pressure regulator valve, 5, counterbalance valve.
Embodiment
The utility model is described further with reference to the drawings and specific embodiments：
As shown in Figure 1：A kind of high-speed internal combustion engine simulated exhaust STS system test set, the experimental rig have compensator
3, the compensator 3 is connected to the output terminal of cylinder 1；Water collar 2, the water inlet of the water collar 2 are equipped with the compensator 3
Mouth is located at the nearly port of export of compensator, and water outlet is located at the nearly input end of compensator 3；It is arranged on the water collar 2 on compensator 3
Cooling water from the nearly port of export of compensator to input end circulation form the adverse current opposite with the flow direction of air in compensator
Circulation；The port of export connection outlet pipe of the compensator 3；Counterbalance valve 5, and the back of the body are provided with the gas pipeline
Pressure regulator valve 4 is additionally provided with pipeline between pressure valve and compensator.
Compressed air enters gas pipeline, successively heats by heater box, enters after eduction valve overflow and vacuum tank voltage stabilizing
Cylinder 1, gas is discharged into compensator 3, water collar 2 is provided with compensator 3, lead to after a series of works done are carried out in cylinder 1
Cross the high-temperature gas that adverse current cooling water discharges cylinder 1 to cool down, then, the gas to have cooled down passes through pressure regulator valve 4 and back pressure successively
Valve 5 is discharged from air outlet slit.
The cooling provision of circulated in countercurrent cooling water is employed on the utility model compensator 3, can effectively reduce to go out from cylinder 1
The temperature of the high-temperature gas come, protects pressure regulator valve 5 not to be burned, guarantee test is smoothed out.
