What is the sudden noise from Bora exhaust pipe?

Bora (check the transaction price | model details) The reasons for the sudden abnormal sound of the exhaust pipe are: 1, the concentration of mixed gas is too high, and the unlit mixed gas enters the exhaust pipe and backfires when it meets fresh air; 2. Poor valve sealing and insufficient combustion; 3. Some exhaust valves are ablated or poorly sealed; 4. The joint surface of the intake valve, exhaust valve and seat ring is padded with carbon deposit; 5. There is no gap in some valve foot pads, and the two idle holes of dual-chamber oil are unevenly adjusted or blocked; 6. The exhaust pipe is damaged and cannot be silenced and purified.

The sudden abnormal noise of Bora exhaust pipe caused the abnormal noise of Bora exhaust pipe, which may be due to the unstable idle speed of the vehicle. There are many reasons for the unstable idle speed of vehicles. When the idle speed is unstable, the sound of natural exhaust pipe is different from usual.

According to different models and designs, there are many reasons:

1, air intake system leakage or blockage will lead to.

2. Idle speed control part: stepper motor and throttle body are dirty or leaking.

3. The sensors such as air pressure, temperature and throttle position are abnormal and the data is incorrect.

4, blocking, unobstructed, etc. Will lead to.

5. The electric fuel pump is abnormal or the fuel filter is blocked or transportation is blocked due to various reasons;

6. Abnormal fuel nozzle: It can be caused by its own quality failure, or by various defects such as foreign body blockage, poor sealing and rubber ring aging.

The poop-poop sound of the exhaust pipe may be caused by water accumulated in the exhaust pipe. This kind of stagnant water may be produced after gasoline is completely burned, or it may be formed by the accumulation of water and carbon dioxide, or it may flow in when washing the car. You can find an uphill place, put it in neutral, step on the accelerator a few times, and there will be no sound when the water is released.

Exhaust pipe is a part of engine exhaust system, which mainly includes exhaust manifold, exhaust pipe and muffler. The three-way catalytic converter for controlling the emission of engine pollutants is also installed in the exhaust system, and the exhaust pipe generally includes a front exhaust pipe and a rear exhaust pipe.
