5 potential solutions for fleet engine idling reduction

By Verizon Connect Team June 5, 2024

“Idling” refers to running a vehicle’s engine when it’s not moving, such as when you’re at a red light or stuck in traffic. Idling is part of the process of driving a car and is a common occurrence for most drivers. However, idling may not be the best for your car, fuel consumption, or the environment.

Reducing the amount of time vehicles are idling is a simple way to maintain and even increase fuel economy among fleet vehicles, especially as fuel prices rise.

Is idling bad for your engine?

Letting a vehicle idle does more damage to the engine than starting and stopping. In fact, running an engine at low speed (idling) causes twice the wear on internal parts compared to driving at regular speeds. (1)

Excessive idling can also cause a buildup of carbon residue in a truck’s engine. Because the engine is not operating at its optimal temperature when idling, fuel is only partially combusted, leading to fuel residue buildup on the cylinder walls. This can further damage engine components, including spark plugs and exhaust systems, increasing maintenance costs and shortening the life of the engine.

Idling and fuel consumption

Idling vehicles can use more gas than you might realise. This directly affects how much you spend on gas and how often you need to refuel. However, the amount of fuel a vehicle consumes while idling varies depending on factors such as its weight, engine size, and the type of fuel it takes. Some states and local governments even have anti-idling laws that restrict engine idling and impose fines on drivers who violate them.

Engine idling and the environment 

Idling and wasted fuel also have a serious environmental impact. Engine idling is particularly bad for air quality, and the World Health Organisation estimates that air pollution is responsible for 4.2 million deaths each year (2) and engine idling is one thing that contributes to this bad air quality.  

According to research, “air pollution is the world's single greatest environmental cause of preventable disease and premature death. In Australia, it's linked to more than 3,200 deaths a year at an estimated cost of A$6.2 billion”. (3)

Also, the Department of Climate Change, Energy, the Environment and Water states that “our transport sector made up 19% of Australia's emissions of the total emissions of the country and without intervention, the transport sector is projected to be Australia's largest source of emissions by 2030”. (4)

Also, a recent report found that “in normal traffic conditions, Australians likely idle more than 20% of their drive time”.(5) This “contributes 1% to 8% of total carbon dioxide emissions over the journey, depending on the vehicle type” (6). To better understand “removing idling from the journey would be like removing up to 1.6 million cars from the road”. (7)

5 potential solutions for engine idling reduction 

For many people, reducing the amount of time spent with your engine running is a priority, if not a necessity. For instance, though everyone can benefit from fewer idling cars on the road, business owners who have to manage their fleet of vehicles stand to save money by reducing idling time.

  • For drivers of small vehicles, it is recommended you turn off your engine if you plan to idle for longer than 10 seconds. It is a common myth that restarting your engine uses more gas and causes engine wear.
  • Don’t idle to warm up your engine, start driving instead. The engine will warm up quicker.
  • GPS fleet tracking software is a way to reduce idling in fleets. This software can be used to gather data about what vehicles and drivers are doing, so fleet managers can see if there are ways to improve performance and reduce time spent idling.
  • Train and coach drivers  as a solution to reducing the amount of time spent idling. Coaching should be constant while teaching drivers to avoid idling can help establish best practices early on. Guidelines for engine idling should be part of your training program and safety culture.
  • Fleet managers and individual owner-operators should consider purchasing auxiliary power units (APUs) to reduce engine idle time. APUs can power trucks during rest periods without using fuel so that drivers can enjoy the comforts of their cabins, such as AC and lights, without burning fuel.

Engine idling may seem harmless, but it has tremendous impacts that negatively affect everyone. It wastes a significant amount of money on fuel and puts harmful toxins into the environment. Keep idling top of mind when you’re driving so that you can do your part to reduce it.
