A thread was started in the container handling,forum about what is better SCR or EGR these might not seem important but over the next 5-6 years they are going to be the largest changes in the industry for forklift that use a engine over 60KW. As from next year these will all come under the new emissions EU3B or TIER iiii in north america. The problem will go further when the next part is introduced in 2014 for engines over 130KW and if the same is added to engines over 60KW it would be harded for the companies who have gone EGR.
At the moment Companies like Kone Cranes and Kalmar have gone with SCR add blue and Hyster and Linde have gone EGR Cummings
How do the engineers who might have worked on these systems think they would go. Or how do the sales who try to sell a system to there customer think the Will go

Hi Misterlift hope you did not mind me copying your thred. I think you are right this will become another function the engineer will have to take on. I can see this becoming quite a task because i'm not sure ware these are located on the trucks. If they are in a hard inescapable place then this will take more time. Some time's designers have a problem fitting these systems into the truck and acceptability is not at the foremost of there mind's. I'm sure this will be more apparent on the smaller trucks like the 5,000kg - 8,000kg range. I'm sure some companies will struggle with this. As for the sales rep like you have pointed out do they know the difference yet. I'm sure the one who sell the bigger trucks will know some thing about them but the other reps might knot. And i'm sure if it's a Hyster linde or a rep who's company use **** engine's will be saying the EGR system is better. Evan tho it seems the SCR system is the better one. I don't know any company apart from one who is planning to use the SCR system on the smaller truck. I think all the engine suppliers in this area have gone for the cheaper to design EGR system.
From an engineer's perspective, it will be interesting if cleaning the soot filter on an EGR system is deemed as a maintenance function (in the same way air filters are cleaned) or if it is seen as a customer practice.
I cannot see customers wishing to see their operators handling hot and heavy filters in and out of a machine that burns the soot away - this will be an additional engineer function.
As regards the sales people, do they know the difference yet?
