PCV Environmental Awareness and Fuel Efficiency 1

Question 1

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

Accepted Answer

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

Answer

Accelerating hard to reach speed quickly then braking sharply

Answer

Driving at maximum speed between stops

Answer

Keeping the engine at a constant high RPM

Question 2

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

Accepted Answer

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

Answer

It has no measurable effect on fuel use

Answer

It keeps the engine warm, improving efficiency overall

Answer

It reduces wear on the starter motor

Question 3

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

Accepted Answer

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

Answer

It uses the engine to generate compressed air for the air brakes

Answer

It automatically applies the brakes when the bus exceeds the speed limit

Answer

It recirculates exhaust gases to reduce emissions

Question 4

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

Accepted Answer

Checking and maintaining correct tyre pressures regularly

Answer

Using wider tyres than specified

Answer

Driving in the highest gear at all times

Answer

Avoiding use of the air conditioning system

Question 5

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

Accepted Answer

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

Answer

A zone where buses must travel at reduced speed to lower emissions

Answer

An area where electric vehicles have priority lane access

Answer

A zone where PCV operators are exempt from congestion charges

Question 6

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

Accepted Answer

It reduces unnecessary mileage, cutting fuel consumption and emissions

Answer

It allows buses to travel faster on all routes

Answer

It reduces driver wages by shortening shifts

Answer

It allows operators to avoid congestion charges
