Environmental Awareness and Fuel Efficiency Flashcards

What driving technique most effectively reduces fuel consumption on a bus route?

Answer: Smooth, progressive acceleration and anticipatory braking (eco-driving)

Smooth, eco-driving — gentle acceleration and anticipatory braking — minimises fuel consumption and emissions.

How does excessive engine idling affect a bus's fuel consumption and emissions?

Answer: It wastes fuel and produces unnecessary exhaust emissions including NOx and particulates

Prolonged idling wastes fuel and emits unnecessary pollutants — engines should be switched off during prolonged stops.

What does 'regenerative braking' do in a hybrid or electric bus?

Answer: It captures kinetic energy during braking and converts it into electrical energy stored in batteries

Regenerative braking recovers kinetic energy during deceleration and stores it as electricity to be reused for propulsion.

Which of the following actions by a PCV driver contributes most to reducing tyre wear and fuel consumption?

Answer: Checking and maintaining correct tyre pressures regularly

Correct tyre inflation reduces rolling resistance, improving fuel economy and extending tyre life.

What is a Low Emission Zone (LEZ) and how does it affect PCV operators?

Answer: A designated area that restricts or charges older, more polluting vehicles including buses that do not meet emission standards

LEZs restrict entry by vehicles that do not meet specified emission standards, potentially charging or prohibiting older buses.

What is the primary benefit of route optimisation for reducing a bus fleet's environmental impact?

Answer: It reduces unnecessary mileage, cutting fuel consumption and emissions

Route optimisation reduces total distance travelled, directly cutting fuel use, emissions, and operating costs.
