Why cant manufacturers just do what ■■■■■■■ did on their M11 engine that was in the ERF EC11. The electronics would turn the engine power down when you were running light and turn itself back up again when loaded or going up hill
That engine was years ahead of its time…shocking how ■■■■■■■ was squeezed out of the big truck market here by the (sometimes inferior) offerings from in-house truck engine manufacturers
There’s something similar in the Iveco EcoStralis now, but I don’t know if any other manufacturer does it.
If the operator thinks the truck is too powerful and has to be downrated it begs the question as to why he didn’t buy a cheaper, less powerful truck with a smaller engine in the first place.
It was almost indestructable, reliable, great on fuel. Just what most operators need and want in a truck. Maybe not the fastest or the best pulling engine, but it always got the job done. And that engine had a nice bark when it was working hard. Sounded much better than todays engines. Am I right in saying they got squeezed out of the UK because they wouldn’t supply big engines that met Euro 3 and beyond? Even if thats so, with ERF and Foden gone, which truck manufacturer would have fitted them in their range? None I reckon, so the writing was probably already on the wall for ■■■■■■■ in the UK. Shame.
I would actually be interested to know what exactly they down rated those engines to, the 380 scanias at Stobies even running heavy pull much better, tbh it feels very much like the old E series I used to drive with an RR Eagle 325 !!!

I think you can get an Axor with 350bhp. More than likely thats what its been turned down to.

All modern electronic engines do this
Power only comes from how much fuel you inject, so as the ECU controls how much fuel it squirts through each injector it controls the engine power. Before electronics the driver’s right foot did exactly the same thing

Yes all modern trucks do to some extent. But if it worked the same way as the ■■■■■■■ idea did, then the truck would run at full power when loaded, which is when you need it most. Then once empty or light, engine power would be reduced to save fuel. The ■■■■■■■ idea IMO, is a much better way of doing things, rather than just downrating an engine and letting it struggle at near or full weight as seems to be the case of the Merc described in the first post. Surely this leads to an increase in fuel consumption.

Being limited to 52,54,56 whatever doesn’t bother me in the least, this is about grunt to pull you up the hills with a reasonable margin of safety, my old Scania 420L would pull me up windy hill on the m62 maxed out weight wise at a minimum of 35/40 depending on wind and the speed I took into the bottom of it, without thrashing it, these Axors have no torque, and frankly I believe dropping to 20mph on a Motorway is not ideal or even safe, heck they even struggle with empty singles on some hills lol
The Axor 12 litre has 2100Nm torque @ 1100rpm
The Scania 12 litre 2100 Nm between 1000 and 1400 r/min
Reckon your Axor is busted if all you can manage is 20mph down the M20.

Read something like this the other day about the Iveco EcoStralis:
"Designed to reduce fuel consumption, EcoSwitch is an important aid for the driver.
EcoSwitch activates a program called iEco which automatically adapts shift logics and engine mapping to the load:
o allowing the engine to supply maximum torque and power when needed
o and “reducing” the power and torque as soon as possible to optimise fuel consumption"
