Stall Test Steps and Results Analysis
The steps of the stall test included the following steps: First, raise the oil temperature of the automatic transmission to 50 degrees to 80 degrees. Then, he fixed the front and rear wheels with triangular wood and braked the car with the parking brake. Next, he kept the engine running at idle speed and placed the gear selection handle in D and R respectively for testing. During the test, the left foot stepped on the brake pedal, and the right foot stepped on the accelerator pedal to the bottom. The engine speed value at the stable state was quickly read out, which was called the stall speed. For the analysis of the stall test results, it was first necessary to compare the measured stall speed with the data in the maintenance manual to see if it met the requirements. If the stall speed of the D and R gears were the same and both were lower than the specified value, it meant that the engine power was insufficient. If the stalling speed is lower than the specified value of 600r/min, it means that the one-way clutch of the guide wheel of the torque-converting device slips. If the speed of the D and R gears exceeded the specified value, it might be due to insufficient oil, low oil pressure in the oil pump, poor oil quality, low main oil pressure, etc., causing the clutch to slip. If the speed is too high, higher than the specified value of 500r/min, it may be that the pitch changer blades are damaged. If the speed of the D gear is higher than the specified value, and the speed of the R gear is normal, it means that the front clutch or brake is slipping. It may be caused by the wear of the clutch friction plate or the low control oil pressure, or the failure of the oil pump or the pressure regulating valve. In summary, the stall test steps include raising the oil temperature, fixing the wheels, applying the brakes, idling the engine, and reading the stall speed value. The result analysis was to compare the stall speed with the data in the maintenance manual to determine the performance and working condition of the engine and automatic transmission.
stall test
Stall test was a method to analyze and judge the performance and working condition of the engine and automatic transmission by measuring the highest speed of the engine when the transmission was in D and R gears. The test steps included raising the oil temperature of the automatic transmission to 50 - 80 degrees Celsius, fixing the front and rear wheels with triangular wood and braking the vehicle with the parking brake, keeping the engine running at idle speed, and placing the gear selection handle in D and R gears for testing. During the test, the left foot stepped on the brake pedal, and the right foot stepped on the accelerator pedal to the bottom. The engine speed value at the stable state was quickly read out, which was called the stall speed. The purpose of the stall test was to analyze and judge the performance and working condition of the engine and automatic transmission, as well as to check whether the clutch, brake, and other shift execution components in the hydraulic moment conversion and automatic transmission were working normally. By comparing the measured stall speed with the data in the maintenance manual, it could be judged whether it met the requirements. If the stalling speed is lower than the specified value of 600r/min, it means that the one-way clutch of the guide wheel of the torque-converting device slips. The stall test needed to be carried out on a wide level ground to ensure that there were no obstacles, and personnel were not allowed to approach the test vehicle to prevent accidental injuries. At the same time, the driving brake and the parking brake must be effective and reliable at the same time. It was necessary to insert a certain height of triangular blocks on the front and rear wheels of the car.
Stall test, how many revolutions are normal?
The standard speed for the stall test was about 2300r/min. If the stall speed is consistent with the standard value, it means that the automatic transmission's oil pump, main oil pressure, and various shift execution components are basically working normally. If the stall speed is higher than the standard value, it may be due to the low oil pressure in the main oil circuit or the slipping of the shift execution element. If the stall speed is lower than the standard value, it may be due to insufficient engine power or a malfunction of the hydraulic moment. Therefore, the normal speed of the stall test should be around 2300r/min.
Stall test speed is more or less normal
The normal speed of the stall test could be compared to the range of 10 - 15% of the vehicle speed. Stall refers to the phenomenon that the output speed of the hydraulic moment is zero when the engine is running during normal driving. The standard value of the stall speed varied according to the model, but most automatic transmissions had a stall speed of about 2300r/min. If the stall speed is consistent with the standard value, it means that the automatic transmission's oil pump, main oil pressure, and various shift execution components are basically working normally. If the stall speed is higher than the standard value, it may be due to the low oil pressure in the main oil circuit or the slipping of the shift execution element; if the stall speed is lower than the standard value, it may be due to insufficient engine power. In short, the normal range of the stall test speed should be between 10 - 15%.
Stall test speed is more or less normal
The normal range of speed for the stall test was between 2000 and 2500r/min. Most of the cars 'hydraulic moment convertors were in this range. The stall test was a method that did not require the transmission to be disassembled to determine the specific parts of the fault. For example, whether it was the transmission or the transmission, whether it was the mechanical part or the hydraulic control part, and which part was the problem. Stalling experiments could also be used to check if the problem had been eliminated after the fault was repaired.
A tree of peach blossoms, paternity test results
[The results of the paternity test in " Peach Blossoms Under a Tree " have been released.] In the play, after learning that she was Sheng Maolin's biological daughter, she cried and laughed. However, the search results didn't provide any specific paternity test results, so it was impossible to know if the paternity between Sheng Rong and Sheng Maolin was confirmed.
Li Minxuan's Art Test Results
Li Minxuan's art test results were that he was disqualified from the test and his certificate was revoked. According to the results of the Beijing Film Academy's investigation, Li Minxuan violated the exam rules during the exam, including wearing light-colored clothes and revealing personal information. The Beijing Film Academy had zero tolerance for exam discipline, so they decided to cancel Li Minxuan's qualification and revoke all the certificates he had obtained. In addition, the Beijing Education Examinations Institute also conducted a verification of the matter and determined that Li Minxuan's behavior was a violation of the exam, but it did not constitute cheating.
How much is the normal range of the stall test speed?
The normal range of speed for the stall test was between 2000 and 2500r/min. This was the standard value of the stall speed of most car's hydraulic moment convertors. The purpose of the stall test was to determine the specific parts of the fault, including the moment conversion, transmission, mechanical parts, and hydraulic control parts. If the stall speed is higher than the standard value, it may be due to the low oil pressure in the main oil circuit or the slipping of the shift execution element; if the stall speed is lower than the standard value, it may be due to insufficient engine power. In short, the normal range of the stall test speed was 2000 - 2500r/min.
