What are the symptoms of a clogged exhaust pipe in a China 5 diesel vehicle?

[LaLondyn]

Here is a detailed introduction to the symptoms of a clogged exhaust pipe in a China 5 diesel vehicle: 1. Poor acceleration: Difficulty in increasing engine speed and vehicle speed. Restricted exhaust flow reduces air intake, leading to a drop in engine power. 2. Mild backfire: Slight backfire occurs when the engine is rapidly accelerated. When the engine exhaust is obstructed, some exhaust gases remain in the cylinders, diluting the air-fuel mixture and slowing combustion. When the intake valve opens, the still-burning mixture can flow back into the intake pipe, causing a backfire. 3. Abnormal exhaust noise: Sounds from the exhaust system can be heard during rapid acceleration or sudden throttle release. This is a symptom of a damaged three-way catalytic converter, and a broken converter can easily cause engine exhaust blockage.
