Which problem can arise from neglecting engine maintenance?

• A. Improved fuel efficiency
• B. Lower emissions
• C. Higher emissions
• D. Minimized wear and tear

Answer: (C)

Neglecting engine maintenance can lead to higher emissions, which is primarily due to the accumulation of carbon deposits and the deterioration of fuel and air filters. When an engine is not regularly serviced, components such as spark plugs, fuel injectors, and oxygen sensors can become clogged or malfunction, causing incomplete combustion. This results in an increase in pollutants released into the atmosphere, such as hydrocarbons and nitrogen oxides. In well-maintained engines, proper airflow, fuel delivery, and ignition timing help ensure complete combustion, leading to lower emissions. Therefore, when maintenance is overlooked, the engine struggles to operate efficiently, causing it to emit higher levels of harmful substances. Understanding this relationship emphasizes the importance of regular engine upkeep not only for performance but also for environmental considerations.
