Well I promised you that I'd tell you all about about MAN's truck engine Euro-5 line-up on Biglorryblog - and as the official release date for journalists is today well here it is.So let's start with the DO8 four and six-pots fitted in the TGL and TGM range.
On all MAN's TGL and TGM light/middleweight models the Euro-5 story is the same - i.e. EGR, or add nothing as they put it... MAN says that the price jump from a Euro-4 DO8 four-pot to Euro-5 version will be £1,275 while the D08 six-pot Euro-5 price premium will be £2,261. DO8 power ratings will be from 150-340hp, all with EGR for either Euro-5 or EEV models. Fuelling is by common-rail on the new EGR engine range.
Now let's talk MAN heavies at Euro-5 - and in particular the D20 and D26 diesels, previously offered with EGR at Euro-4. For Euro-5 the smaller D20 10.5-litre continues with EGR (indeed MAN insists EGR is still "the dominant technology" for Euro-5) at 360 and 400hp, while the larger 13 - litre D26 is offered at 440 with EGR - then with SCR at 480hp, and at a new 540hp rating, again with SCR - and pictured above is a typical AdBlue installation on a previous TGA MAN tractor chassis - all very neat don't you think? Meanwhile, as before the mighty V8 continues at 680hp with SCR for Euro-5.
Now for some stuff on that new TGX model with the latest 540hp rating - which comes with 2,500Nm of torque. The 26.540 6x2 will boast the largest XXL cab and the by-now-familiar Tipmatic auto (nee ZF AS-Tronic) as standard fare too. It's aimed at international/long haul operators who want high-horsepower but who are probably reluctant to go for a fire-breathing TGX V8! Click through here for more... And BLB's take on the whole shebang.
Well no doubt some BLB readers are saying: "SCR? I thought MAN was wedded to EGR and nothing else would do?" Well interestingly enough at last week's press bash MAN declared: "We've always offered both EGR and SCR Engine Technologies for Euro-4 and Euro-5.." All of which is true although naturally in the UK it's biggest marketing push has been on EGR. So will operators be put off by a lack of EGR at power ratings above 440hp? And what about those MAN customers who previously bought the D20 EGR Euro-4 engine at 440hp? Now, if they want the same rating with EGR they've got to go to the heavier, and larger-capacity D26.
Doubtless MAN's rivals will also say: "We told you they needed SCR for Euro-5..." Although it's actually only at the top end. However, the argument over EGR vs SCR is frankly starting to lose any significance - especially as it's generally accepted that for Euro-6 (expected around 2012 and 2013) you'll need both technologies. Although as one MAN insider told BLB last week when the conversation turned to Euro-6: "It's not about how much EGR you'll need with SCR - it's about how much SCR you'll need with EGR!" Nice footwork guys...
Of course the real issue with EGR has been cooling - and at higher horsepower ratings its struggled to keep pace as emission levels have got tighter. Although it's interesting to note that Scania has managed to do it with its Euro-5 480hp 13-litre, even if we haven't seen EGR on the Swede's big vee engine. I wonder if we'll ever see that doing without AdBlue?
And as a sign off the MAN marketeers now talk about MAN 'Pure' Diesel...
