The automotive exhaust pipe is a critical connecting and conveying component of the engine's exhaust and ventilation system, encompassing pipelines that connect the engine to the main exhaust system, as well as exhaust conveying pipelines in the crankcase ventilation system. Its core function is to guide exhaust emission, optimize combustion, and ensure stable engine operation.

Typical Faults and Maintenance Recommendations

Common Faults: Prolonged exposure to high temperatures and oil vapor erosion can lead to aging issues in the exhaust pipe, such as hardening and cracking of rubber materials, and embrittlement and damage of plastic materials. Wear of the sealing ring at the joint can cause exhaust leakage, which in turn may result in engine idle vibration, poor acceleration, and heavy exhaust odor. If the pipeline is clogged, it will cause poor exhaust discharge, not only reducing engine power but also potentially leading to abnormal increase in exhaust noise.

Maintenance points: It is recommended to inspect once every 20,000 to 30,000 kilometers, focusing on checking whether the pipeline is damaged and whether the joints are loose or leaking. When aging or damage is found, original factory parts compatible with the vehicle model should be replaced. When replacing, oil stains and impurities at the joint can be cleaned simultaneously. For corrugated or other types of pipelines prone to dust accumulation, regularly clean surface dirt to avoid affecting heat dissipation and structural stability. If the crankcase ventilation exhaust pipe is equipped with components such as electromagnetic valves, attention should be paid to the functional matching of accessories during replacement to ensure exhaust control accuracy.
