Regular inspection of an engine's air filter is critical for maintaining optimal vehicle performance and fuel efficiency. Over time, airborne dirt and debris accumulate on the filter pleats, restricting airflow to the combustion chamber. When airflow is choked, the engine burns more fuel to compensate, leading to increased emissions and sluggish acceleration. While replacing a dirty filter takes only a few minutes and requires minimal tools, ignoring it can eventually foul spark plugs and strain engine sensors. Routine air filter maintenance prevents unnecessary fuel waste and protects internal components.
Which of the following statements best expresses the main idea of the passage?
- AReplacing a dirty air filter takes only a few minutes and requires minimal tools.
- Regularly maintaining an engine's air filter is essential for preserving vehicle performance and fuel efficiency.Cevap
- CAccumulated debris on filter pleats directly restricts airflow to the combustion chamber.
- DNeglecting air filter replacement will immediately cause complete mechanical failure of the engine.
Cevap
Regularly maintaining an engine's air filter is essential for preserving vehicle performance and fuel efficiency.
The passage begins and concludes by highlighting that routine air filter inspection and replacement are necessary to maintain fuel efficiency and protect engine components. Every other sentence provides supporting evidence detailing why this maintenance matters (preventing restricted airflow, extra emissions, and fouled plugs).
