Firstly, due to their flexibility, automotive fuel hoses should be closely monitored for expansion during testing. The expansion of a hose may affect its sealing performance, so the test equipment needs to be able to accurately measure and record the deformation of the hose under pressure. Secondly, the effect of temperature on test results should not be ignored. The same fuel hose may show different airtightness performance under different temperature conditions. Therefore, the ambient temperature should be strictly controlled during the testing process and the temperature data during the test should be recorded to ensure the accuracy and repeatability of the test results.

1. Pressure control: The testing equipment will be equipped with a precise pressure control system, which can accurately regulate and maintain the test pressure, which helps to prevent over-expansion caused by high pressure. 2. Real-time monitoring: Advanced testing equipment is usually equipped with high-precision sensors and monitoring systems, which can monitor the expansion of the hose in the testing process in real time. This data can be used to analyse the behaviour of the hose under different pressures and adjust the test parameters accordingly. 3. Temperature control: Since temperature changes affect the physical properties of the hose, testing equipment usually includes a temperature control system to maintain a constant temperature in the testing environment. 4. Data recording and analysis: Modern testing equipment is able to record detailed test data, including pressure, temperature and degree of expansion. 5. Flexible fixture design: In order to accommodate the expansion of the hose, the fixture design of the testing equipment is usually flexible, allowing the hose to expand naturally during the test while maintaining the necessary sealing. 6. Simulation of actual working conditions: In order to more accurately assess the performance of the hose in actual use, the testing equipment may simulate the actual working conditions of a vehicle during operation, including factors such as temperature, pressure and vibration. Considering the physical properties of the hose and the effect of ambient temperature, the air tightness of automotive fuel hoses can be more accurately assessed, thus safeguarding the safety of the automotive fuel system.
