[0024] Working principle: When in use, step on the positioning plate 12, the positioning plate 12 slides downward and squeezes the buffer spring 11. When the positioning plate 12 slides, the top rack is out of contact with the tooth groove at the bottom of the detection platform 4. Slide the detection platform 4 so that the detection platform 4 is located outside the frame 3, loosen the bolt 1 7 and the bolt 2 9, slide the slide plate 6 and the slide block 8, so that the base 10 corresponds to the position of the engine base 10, and then tighten the bolt 1 7 and the bolt 2 9. Place the engine on the base 10 and fix it with an external crane, then slide the detection platform 4 in the opposite direction and press the positioning plate 12 to make the detection platform 4 and the engine enter the inside of the frame 3, loosen the positioning plate 12, so that the rack on the top of the positioning plate 12 is engaged with the tooth groove at the bottom of the detection platform 4 and fixed, and then rotate the detector The joint of one 13 is connected to the exhaust port of the engine, and the engine is connected to the external control system and the power supply system. The engine is started through the external control system and the power supply system, and the exhaust gas generated by the engine enters the detector one 13 through the exhaust port, and is detected by the detector one 13. The detected gas enters the inside of the three-way catalytic converter 14 through the intake pipe 15, the sleeve 18 on the intake pipe 15 and the fixed pipe 1401 on the top of the three-way catalytic converter 14, and after being filtered by the three-way catalytic converter 14, it enters the detector two 17 through the bottom fixed pipe 1401 and the sleeve 18 on the detector two 17. The detector two 17 detects whether the filtered gas meets the exhaust standard. When the exhaust standard is met, the exhaust pipe 16 valve is opened, and the filtered gas is discharged. The gas is discharged through the exhaust pipe 16. When the exhaust standard is not met, turn off the engine, loosen the two sleeves 18, replace the three-way catalytic converter 14, and when the gas in the detector 13 enters the intake pipe 15, the baffle 23 is moved by pressure, driving the inner rod 27 to slide in the groove of the outer tube 25. When the inner rod 27 slides, it squeezes the limit spring 26, and the baffle 23 slides to separate from the inner wall of the fixing ring 22. The gas flows inside the intake pipe 15 through the channel of the fixing ring 22. After the test is completed, loosen the joint of the detector 13 to separate the engine exhaust port from the detector 13, start the air pump 20, and the residual gas from the engine exhaust port and the detector 13 is discharged from the connecting pipe 19 into the intake pipe 15 through the suction pipe 21 and the air pump 20. When no gas enters the detector 13, the thrust of the limit spring 26 drives the inner rod 27 and the baffle 23 to slide, and the baffle 23 closes the fixed ring 22 to prevent the gas from the connecting pipe 19 entering the intake pipe 15 from overflowing from the channel of the fixed ring 22. The gas in the intake pipe 15 enters the three-way catalytic converter 14 through the sleeve 18 on the intake pipe 15 and the fixed pipe 1401 on the top of the three-way catalytic converter 14. After being filtered by the three-way catalytic converter 14, the gas enters the detector 2 17 through the bottom fixed pipe 1401 and the sleeve 18 on the detector 2 17. The detector 2 17 detects whether the filtered gas meets the exhaust standard. When the detection reaches the exhaust standard, the exhaust pipe 16 valve is opened, and the filtered gas is discharged through the exhaust pipe 16.
