Incomplete combustion caused by carbon and soot deposits leads to higher emissions of harmful pollutants, including carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx). These emissions contribute to air pollution, smog formation, and adverse health effects in humans.
Carbon and soot deposits can damage the catalytic converter, a critical emissions control device in modern vehicles. A compromised converter is less effective at converting harmful pollutants into less harmful substances, resulting in higher emissions and potentially costly repairs or replacements.
Incomplete combustion due to carbon and soot deposits can result in engine knock or pinging, which is the premature ignition of the air-fuel mixture. This can cause engine damage over time and reduce overall performance.
