Test method for measuring economical efficiency of automobile fuel oil based on drum test bench

The invention discloses a test method for measuring automobile fuel economy based on a drum test bench, and relates to the technical field of automobile fuel detection, and the method comprises the following steps: detecting the vehicle state of a test vehicle; marking the fixed position of the test vehicle; performing test pretreatment on the test vehicle; carrying out vehicle immersion operation on the test vehicle; and the OBD reading equipment is used for testing the test vehicle to obtain test data. The method can be used in high-temperature, normal-temperature and low-temperature test environments, and the fuel economy difference measurement precision is high; through limitation of the environment, the vehicle state and the fixed position, the consistency of multiple test results is improved. 本发明公开基于转鼓试验台的测量汽车燃油经济性试验方法，涉及汽车燃油检测技术领域，包括以下步骤：对试验车的车辆状态进行检测；对试验车的固定位置进行标记；对试验车进行试验预处理；对试验车进行浸车操作；通过OBD读取设备对试验车进行试验获取试验数据。本发明在高温、常温、低温试验环境下均可用，燃油经济性差异测量精度较高；通过对环境、车辆状态、固定位置的限制，提高多次试验结果的一致性。
