What is the problem when the exhaust pipe makes a popping sound and shakes?
1 Answers
Reasons for the popping sound in the exhaust pipe: 1. Fuel system: Issues such as fuel line blockage, poor flow, or rail pressure can cause this. Abnormalities in the electric fuel pump or blockages in the fuel filter due to various reasons can also lead to restricted fuel delivery. 2. Fuel injector issues: Malfunctions due to poor quality, blockages caused by foreign objects, poor sealing, aging O-rings, and other defects can contribute to the problem. 3. Air intake or idle control: Problems with the stepper motor, dirty or leaking throttle valve body, or abnormalities in sensors such as atmospheric pressure, temperature, and throttle position can result in incorrect data. The automotive exhaust bellows, also known as the exhaust pipe flexible hose, is installed between the engine exhaust manifold and the muffler. It provides a flexible connection for the entire exhaust system, reducing vibration and noise, facilitating installation, and extending the lifespan of the exhaust muffler system. It is mainly used in light vehicles, microcars, and buses. Its structure consists of a double-layer corrugated pipe covered with a steel wire mesh sleeve, with clamping rings on both straight ends. To enhance noise reduction, an expansion joint or mesh sleeve can be added inside the bellows.
