Scania is claiming that its new Super 11 bus and coach engines will offer buyers a wide range of benefits including potential fuel savings of up to 10 per cent, along with much longer engine life and improved serviceability and compatibility with renewable fuels, along with better braking power.
Scania has launched its new 11-litre option, which it calls the Super 11, just six months after the launch of its game-changing 13-litre Super bus and coach powertrain.
Scania says that its new Super 11 extends its portfolio of the most efficient combustion powertrain platform it has ever developed, providing further alternatives for bus operators.
It will be relevant for a wide range of operators, including companies running urban routes and longer inter-city routes, with the Super 11 offering more fuel-efficiency than Scania’s nine-litre, with output options of 350, 390 and 430 hp, meaning it also has the power to handle a range of applications for which the 13-litre is currently used.
The main headline for the new powertrain is apparently its remarkable fuel efficiency potential, along with much longer engine lifespan, improved serviceability and compatibility with renewable fuels, and its new Variable Valve Braking technology.
The fuel efficiency benefits in particular, also stand out, with claimed ten per cent fuel savings compared with its predecessors.
Part of those fuel savings comes from the inclusion of what Scania is calling Variable Valve Braking or VVB.
It says VVB combines compression release brake technology from the new 13-litre engines with cam phaser technology from the new Super 11, creating braking power of up to 350kW.
Scania says that depending on customers’ operating conditions, Variable Valve Braking can replace the retarder, saving a 80kg in weight. it says VVB also contributes to better fuel consumption and lower emissions while providing quieter braking and greater control.
The company says that the new Super 11 is compatible with the renewable fuels HVO and biodiesel (FAME).
Among the other key advantages Scania cites are a longer engine lifespan of up to two million kilometres and a 25-per cent increase on the previous equivalent.
The company is also trumpeting improved serviceability as a result of the oil and fuel filters being positioned next to each other on the cold side of the engine, rather than on the warm side that is the case with its predecessors.
Scania says this means there is no longer any need to wait before the engine has cooled down before any replacement work is done, reducing the amount of downtime in the workshop and the risk of losing revenue.
In addition to this, Scania says that new rear axles and auxiliary brakes offer better performance and handling, while a new after treatment
system with twin SCR for Euro 6, offers excellent fuel savings and increased uptime.
“The new Super 11 powertrain will help many Urban and Travel segment customers reduce their CO2 footprint, while also providing an economically competitive solution that meets their business needs now and in the years ahead,” said Scania’s global head of business solutions for people transport solutions, Anders Liss.
“As perhaps the most efficient combustion powertrain on the market, it will be a very strong solution for operations where there will be a continuing need for combustion technology,” Liss said.
