What is the main cause of erosion in the silencer?

The main cause of erosion in the silencer is primarily attributed to contamination in the fuel oil. When fuel oil contains impurities, such as water, dirt, or other particulates, it can lead to improper combustion and result in the production of harmful by-products. These by-products can generate corrosive effects within the exhaust system, including the silencer, leading to increased erosion.

The contaminants create a harsher environment for the materials within the silencer, promoting degradation over time. This erosion can manifest as pitting, thinning, or holes in the silencer walls, ultimately affecting the performance of the entire exhaust system and potentially leading to more significant mechanical issues. Understanding the impact of fuel oil contamination is crucial for maintaining the integrity and operational efficiency of the silencer.
