[KeiraMarie]

The reasons for the buzzing sound when the Baojun 730 is running are: 1. Air leakage in the engine intake pipe; 2. Improper installation of the air filter or detachment of the vacuum hose; 3. Excessive tire pressure leading to wear on the tire crown and reduced shock absorption; 4. Wear and looseness of the wheel hub bearings. Solutions: 1. Check whether the chassis screws are loose and inspect if the lower control arm bushings are loose; 2. Check if the valve clearance is adjusted to the appropriate position, and adjust it if there is any displacement. Taking the 2021 Baojun 730 Manual Fashion 7-seater as an example: It is an MPV launched by SAIC-GM-Wuling, with a length, width, and height of 4780mm, 1780mm, and 1740mm respectively, and a wheelbase of 2750mm. It is equipped with a 1.5T turbocharged engine, with a maximum power of 108kw and a maximum torque of 250nm, paired with a 6-speed manual transmission.
