Well I probably dont deserve any answers after making a nuisance of my self before
but if you dont ask you dont get
So trying to save fuel on the job I found this link en.wikipedia.org/wiki/Energy-eff … g#Drafting
Now there is a table published with the result of how much fuel you will save driving up close behind a lorry in your car
As the lorry would shelter the car from the front coming wind
I can see this working for a car as the car is smaller then the lorry
But how much do you actually think it would work by a lorry following another lorry?
some of the distances in the table sound far far to close but a 10% saving at 30m/ 100ft sound worth it to me and safe enough
How much do you think is a safe distance?
Another idea I have been toying with is what my CPC trainer told me last week (has 1/2 dozen wagons him self like)
apparently Scania have brought out a new satellite device that as you reach the top of the hill the throttle cuts off (using no diesel) and you cruise up the last bit of the hill using only your momentum
So Am I right in thinking you are best going as fast down the hill as possible (foot to the floor) and cruising or coasting back up the hill?
Well wind resistance is one of the biggest things that wallops fuel above 50MPH so the drafting thing has some merit to it, especially for those who watch formula 1 and will be aware of the distances it can work at.
The hill thing sounds like a load of crap. Using momentum to crest a hill will result in your speed dropping and you’ll use more fuel making the speed back up. Going down as fast as possible is right though.

Boss and Driver you are slipping mate, you forgot to use the deliberate spelling mistakes to maintain your persona this time. You really must try harder.

I know; but I do try hard in other aspects
now I have a bit of a problem
Im suffering from a split personality disorder and I dont rely know who I am from one minute to the next

I think the scania idea was to use less fuel as possible at the top of the hill
Im thinking that if your driving down hill the kenetic energy you put out will increase its self by going down hill
But when climbing the kenetic energy you put out through the wheel will all be lost due to the hill
Anyone have any figures and facts on lorries drafting behind other lorries
30m doesn’t sound safe at all. You’ll probably cover 10m in thinking distance before brake application as at 50mph you’re covering 22 meters per second. If you’re gonna try it stay the [zb] away from me.

It’s not rubbish we have it on our new Actros’s it’s called Predictive Powertrain Control or PPC for short .
Well I gave the drafting effect a blast today or for as long as I could stay awake
2 white chervals in the middle of the road I got to; where I though it was a safe stopping distance
I could fell A slight affect from moving from the sheltered lorry in the inside lane to moving into an empty middle lane like there was a slight resistance
Anyone know the proper name for those fluorescent markers in the middle of the road is call and how far apart are they from each other?
