The four-axle Euro 6 sewer cleaner's bodywork occupies most of the empty space between the axles. Thanks to Scania's space-efficient Euro 6 solution, with a silencer unit of the same size as for Euro 5, the installation is unchanged.
Despite its compactness, the silencer unit contains all the elements necessary for the complex Euro 6 aftertreatment process. The exhaust gases first pass through and oxidising catalyst that condition the exhaust gases for the next step in the process, through a particulate filter to remove particulate matter, via twin SCR catalysts to remove NOx and then out through twin ammonia slip catalysts that remove any ammonium remaining in the gases. All this is contained inside the silencer.
“Installing such complex bodywork on the Scania Euro 6 chassis was quite straightforward,” says Brian Stage, MD of Danish bodybuilder J Hvidtved Larsen A/S in Silkeborg. “The bodywork is identical to that fitted to a Euro 5 vehicle, which is a great advantage from a cost and lead-time perspective.”
The sewer cleaner is a Scania G 480 8x2 with two steered front axles and a hydraulically steered tag axle behind the driven axle. The 13-litre Euro 6 engine produces 480 hp and a generous 2,500 Nm of torque, which is ample for powering the vehicle as well as the power take-offs for the auxiliaries. The Scania P 310 4x4 has a 9-litre Euro 5 engine and is around 700 kg lighter than a corresponding 13-litre vehicle.
Scania introduced its first Euro 6 engines one year ago to enable foresighted operators to take the first step to the next emission level. Scania Euro 6 vehicles have since been in operation with customers and tested by the press with excellent results.
The Euro 6 legislation will come into force for new models on 31 December 2012 and for all new vehicles one year later. The legislation has now been adopted and enabled Scania vehicles to be registered as Euro 6 in several countries. Incentives to encourage operators to invest in cleaner technology are currently being adopted by authorities in some European countries.
