What is one impact of failing to maintain a vehicle properly on emissions?

Failing to maintain a vehicle properly can lead to a higher emissions output, which is a significant environmental concern. When a vehicle is not well-maintained, components such as the engine, exhaust system, or emission control devices may not function optimally.

For example, if the engine is running inefficiently due to a dirty air filter or malfunctioning spark plugs, it can burn fuel improperly. This incomplete combustion can result in an increase in harmful emissions, such as carbon monoxide, hydrocarbons, and nitrogen oxides. Similarly, if the catalytic converter is damaged or clogged, it won't effectively reduce toxic emissions before they exit the exhaust system.

On the other hand, enhanced engine performance, lower fuel costs, and improved safety features typically stem from regular maintenance practices. Therefore, neglecting proper vehicle upkeep directly contributes to the problem of increased emissions, emphasizing the importance of routine maintenance for both environmental protection and vehicle efficiency.
