After nearly three years in operation, a Scania Euro 6 truck has accumulated an impressive 1.1 million kilometres.
Scania has been a Euro 6 leader and a little over one year before production of the new engines was started, selected customers in Germany, Sweden and Switzerland were given the opportunity to try out this new technology in their operations. During testing, Euro 6-configured Scania trucks have, in total, accumulated 26 million kilometres – equal to 650 laps around the world.
That Scania was eager to pioneer this greener technology goes without saying. One of these trucks was put into operation in December 2010 by the haulier “Scania Transport Laboratory”, which shuttles goods between Scania’s production units in Södertälje, Sweden and Zwolle in the Netherlands. “We’ve never before conducted field testing with vehicles that have clocked up so many miles,” says Field Test Engineer Mats Johansson. “During these three years, we’ve benefitted from tremendous feedback on performance.”
Carefully recorded data
The precisely recorded data for the 1.1 million-truck shows an average fuel consumption of 27.93 litres/100 km, a strong result given the type of operation. As expected, the fuel consumption has been higher during winters than summers. Of total costs, fuel accounts for 67 percent, AdBlue for 1.3 percent while maintenance costs constitute 2.3 percent. Expenses for repairs have been slightly higher than normal, which was also anticipated considering the new technology. “But these initial repairs have been invaluable in helping us to increase knowledge,” explains Mats Johansson.
The engine and aftertreatment system has now been dismantled for careful analysis. “We are presently inspecting each and every article, including the cylinder block, pistons and valves,” says Sara Molneryd.
She has headed Scania’s special task force, “Euro 6 Infant Care”. Following two years of intensive efforts, Scania will shortly phase out the task force. “Our focus has been to eliminate all teething problems to reach zero faults in time before the Euro 6 transition from 1 January.”
Nearly all trucks monitored
Meeting twice weekly, the task force has reviewed fault codes from vehicles in operation to initiate swift remedial action. “We’ve been able to monitor practically all rolling Euro 6 Scania vehicles.”
Production of the first Euro 6 engine generation started in February 2012 and Scania could therefore assess results after the initial year during spring 2013. “We can doubtlessly say that the first year with Euro 6 engines in long-haulage operations was stable. The faults that have appeared, have been dealt with and we therefore feel highly confident.”
