Match each vehicle practice or driving habit with its direct impact on fuel efficiency and the environment.
- Leaving an unused roof rack or roof box fitted to the vehicleIncreases aerodynamic drag and burns excess fuel even with no load
- Changing up into higher gears smoothly and earlyKeeps engine revolutions low, reducing fuel consumption and emissions
- Driving on tyres that are significantly under-inflatedIncreases rolling resistance, causing uneven tyre wear and higher fuel use
- Leaving the engine running while waiting in a stationary queueWastes fuel needlessly and creates avoidable local exhaust pollution
Cevap
Leaving an unused roof rack fitted matches with increasing aerodynamic drag; changing up into higher gears early matches with keeping engine revolutions low and reducing fuel consumption; driving on under-inflated tyres matches with increasing rolling resistance; and leaving the engine running while stationary matches with wasting fuel needlessly and creating avoidable local emissions.
Each driving practice directly corresponds to a specific physical mechanism affecting fuel economy and emissions: roof attachments create aerodynamic drag, early gear selection reduces engine speed and fuel flow, under-inflated tyres raise rolling resistance, and unnecessary stationary idling produces pure waste of fuel and localised pollution.
