Hello Hello.
I am looking for numbers regarding the following question:
From how much downtime is it better to completely shut down the engine rather than idling it, given the fact (I presume) that starting an engine consumes more fuel than idling .
I could find on a forum a notice of qq1 citing the figures of the ademe (without possibility to check, or in any case I did not find on their site and I did not send an email to ask) who say that beyond 30 dry, it is better to turn off the engine.
What do you think?
And if not thanks to this question which I asked myself, I discovered that Citroen had implemented a system "stop and start" on their C3 and C2, which cuts the engine automatically when one is at the stop and that as long as you press the brake pedal.
When it is released, in a completely transparent and fast way, the engine restarts and we do not even feel any difference with a car not equipped with this system.
A VERY GOOD point for Citroen!
And if not about the first story of this subject:
# As far as possible, let your engine warm up before starting to drive. For example, start it before putting on your seatbelt ... a few seconds of warm-up never hurts. Don't "pull" on it when it's cold! This greatly increases the wear and tear of your engine and creates significant overconsumption.
What is the optimal time to leave the engine running before putting the car in motion?
5 dry to put his belts are they enough?
We look forward to seeing you!

Edit: I just found this:
Shut off the engine in the heat (long fire)
This approach still assumes that the engine is hot (it restarts very easily).
We all arrive at a fire that has just turned red and we know we have for a minute. It seems to me relevant to turn off the engine in this case. This is even more relevant when there are big traffic jams or when waiting for several minutes. Some argue that it reduces the life of the battery but I do it systematically since 7 years and have not yet changed battery more than 100 000 km (it is just starting to show some signs of weakness). The outstanding question is the estimated minimum waiting time. In general, we say 30 seconds but I have already read 10 seconds. It is therefore necessary to apply this quite often in the city.
