Quality inspection：
Noise and vibration inspection
Noise and vibration inspection is mainly to test whether the sound of the vehicle during operation meets the regulations, especially when driving at high speed or under heavy load. Components such as the engine, exhaust system, chassis and body may produce noise and vibration, and it is necessary to ensure that these noises are within the allowable range. Check whether there are any abnormal sounds when the engine is running, such as knocking sounds, friction sounds, etc., to avoid excessive noise caused by component failure or wear. Body vibration detection should ensure that the vehicle does not produce excessive body vibration or instability when driving at high speed, which can improve driving comfort and extend the service life of the vehicle.
Environmental emission inspection：
Environmental emission inspection is to test whether the engine emissions of three-wheel cargo motorcycles comply with local environmental standards. Check whether the emission system is working properly to ensure that exhaust gas can be effectively processed through catalytic converters, mufflers and other equipment to reduce harmful gas emissions. Test the emissions of vehicles under different loads to ensure that they meet national or regional environmental protection standards. The fuel consumption level of the vehicle also needs to be tested to confirm whether the fuel consumption meets the regulations to avoid energy waste and excessive operating costs. Pass emission tests to ensure that vehicles comply with the latest policies and regulations in terms of environmental protection.
