Why does a new car have excessive exhaust emissions?
2 Answers
Main reasons include the use of low-quality fuel, a clogged catalytic converter, or malfunctioning oxygen sensors. Below is relevant information about excessive vehicle exhaust emissions: Vehicles prone to excessive emissions: This issue is commonly seen in older vehicles, such as cars over 10 years old, which often exhibit blue smoke due to oil burning. Penalties for excessive emissions: Vehicles caught exceeding emission standards by surveillance cameras will be penalized by traffic police authorities, with drivers facing fines and demerit points.
I think excessive exhaust emissions from new cars are quite common. I've experienced it myself with my new car, possibly because the engine wasn't properly broken in yet, or due to poor-quality gasoline causing incomplete combustion. Additionally, if sensors like the oxygen sensor malfunction, the computer reads inaccurate data, leading to excessive emissions. My first suggestion is to take it to a professional shop for an exhaust gas analyzer test instead of randomly tinkering with the car. New cars might not have been tested strictly before leaving the factory, or their systems could have been affected during transportation. Also, pay attention to daily driving habits—avoid frequent rapid acceleration and deceleration, as that worsens emissions. Regular maintenance is crucial too, like checking the exhaust pipe and catalytic converter every 5,000 kilometers to prevent major issues. In short, don't panic too much; address it early to avoid harming the environment and wasting money.
