Driving technique for braking in the city

[Christophe]

I haven't had this problem since we moved to the flat country ...

Hello Did67

So in a discussion on fuel savings in France, this is as incongruous as imagining the pope promoting the morning after pill in a slum in Sao Paulo!

[Off-topic mode = ON]
It is normal, for our last popes the pure and hard doctrine goes well before the life of the people and there is no question of promoting contraception in any form, even if they know perfectly well that many uninformed people will die from AIDS.

When the road descends sufficiently, it is therefore much better to lift your foot but stay engaged and consume "0 l / 100 km" because the ECU cuts off the injection - rather than disengaging and consuming the figures indicated.

Of course, if it goes down less, you will have to consume a little so as not to slow down (by declutching or accelerating very very slightly - a priori, my calculator does not give me a significant difference but this is not easy to measure).

Having tried a certain number of rental cars and looked at the instantaneous consumption given by the calculator, my conclusion is that for very low indications in descent, slowed down and very low rev this usually marks anything.
A+

Yes, I think I made a dumpling


Well, I stop, it is promised. Excuse me for the interruption.

christine i didn't understand

but always enjoyed the meatballs if you have a good recipe ....
I only ate it in Flanders but you must have that

[Christophe]

NO WE DON'T EAT IT !! Did you lost your mind!!

[Christine]

No, it was just to give some relief to the subject of this conversation, but since it falls flat ...

This time I leave you

[georges100]

pity christine .....

do you think the injection computer is capable of delivering less than at idle? possible on new models ... In this case, if the engine brake is weak the grip can be more interesting, actually.
on mine, I suspect it does not cut the injection at all, and the engine brake certainly represents more than maintaining idling ...

Yes, it cuts. My Xantia 1.9 Turbodiesel was already doing this. I had a problem with the small internal solenoid valve ...

Speaking of engine brake, how to explain, despite the total absence of injection, the big decrease in engine braking on recent diesel?
