Hazards of Emission Control System Failure?

Hazards of emission control system failure include increased fuel consumption and reduced engine lifespan. Below is a detailed introduction to the hazards of emission control system failure: 1. Increased fuel consumption: It will lead to higher fuel consumption, and over time, poor combustion efficiency can result in excessive carbon buildup. 2. Reduced lifespan: It can create safety hazards during driving and shorten the engine's service life. During vehicle operation, faults in the fuel supply system, ignition system, etc., can cause engine overheating, backfire, leading to sintering and peeling of the three-way catalytic converter substrate, increased exhaust resistance, etc. The air-fuel mixture correction loses its basis, causing inaccurate fuel injection control by the ECU, which over time will affect the engine's lifespan.
When driving, I've noticed that emission system failures are truly troublesome. Not only do they make exhaust fumes pungent and unpleasant, but they also worsen environmental pollution by releasing harmful gases like nitrogen oxides that contribute to urban smog and acid rain, affecting everyone's respiratory health. Vehicle performance deteriorates too - the engine hums weakly with reduced power, fuel consumption spikes dramatically, and driving efficiency plummets. If left unrepaired, long-term damage may occur to other components like sensors or catalytic converters, often resulting in exorbitant repair costs. There are legal risks as well; exceeding emission standards can lead to traffic police fines or failed annual inspections - last year this caused me several days of delay. Overall, such malfunctions bring multiple hazards. Regular inspections and maintenance are essential to avoid extra expenses and health issues, ensuring both peace of mind and cost savings while driving.
