Is an Emission System Malfunction Dangerous?

[DelMatthew]

An emission system malfunction is indeed dangerous, and here are the potential impacts of such a malfunction: Affects fuel consumption and reduces engine lifespan: It can impact fuel consumption, and over time, poor combustion may lead to excessive carbon buildup. While it doesn't directly cause engine damage in the short term, an emission system malfunction can compromise the safety of the vehicle during operation and shorten the engine's service life. Increased exhaust resistance: During vehicle operation, issues with the fuel supply system, ignition system, or engine overheating can cause the catalytic converter substrate to sinter or flake off, leading to increased exhaust resistance. Environmental pollution: Due to the use of fuel or lubricants, the catalytic converter may become poisoned and lose efficiency. This affects the catalytic conversion process, leading to the formation of sulfur and phosphorus compounds and deposits inside the catalytic converter. Consequently, vehicle performance deteriorates, resulting in reduced power, increased fuel consumption, and worsened emissions.
