This is an old reflex that dates back when car engines played a pleasant and harmonious music. Today an engine idling (or an engine running) is neither nice to hear nor good to breath. Stop it as soon as possible.
THE CONSEQUENCES OF KEEPING YOUR ENGINE RUNNING
There was a time, not so far, where we let our worship engine operation, even at a standstill. Small winter mornings, the justification was “it is to heat.” Large summer evenings, another excuse: “It is for the air conditioning …” in a traffic jam: “I will restart immediately.” A parking lot: “I’m waiting for someone”, etc, etc …
When you’re stopped, your engine must be switched off as soon as possible. Even for a 30 second break. Nothing justifies today to keep engine idling at a standstill for prolonged periods. what for?
First, for ecological reasons. A car engine running highly polluting and rejects not only CO2 as everywhere, but also particles and rare and harmful gases such as carbon monoxide (for a poorly tuned engine) or nitrogen oxide (NOX), which will disturb or worse, pedestrians or cyclists who pass nearby. And this advice also applies when you wait at a red light. Vehicle emits 20 times more greenhouse gas emissions at a red light that when traveling at a speed of 50 kph.
Then for economic reasons: engine running unnecessarily for more than 60 seconds uses more fuel than when it shuts down and restarts. for example a trip into town for 15 km : you’ll stop on average 0.4 times per km. About 6 stops from 1 to 2 minutes, especially at red lights. Or a maximum of 12 minutes stop. An idling engine consumes an average of 1 liter per hour. If you make this trip every day, 2 times a day, without turning off your engine when stopping on the course, you will have consumed after one year up to 90 liters of fuel unnecessarily, more than € 110 wasted .
