New Scania SCR six-cylinder engine family launched as part of modular line-up
Scania has launched a new global modular engine platform that meets all emission standards, with new Euro 5 SCR six-cylinder versions now available in Australia.
Scania has launched a new global engine platform with boosted performance that meets all emission standards and ensures optimum service support across the world.
Scania offers the widest range of heavy-duty trucks on the market, including a comprehensive range of V8 trucks. Now it can also provide a global range of engines, based on the same platform that matches emission standards around the world.
Today, Scania Australia is launching the new Euro 5 engines with SCR technology, which can also operate on up to 100 percent biodiesel.
The new global engine platform takes traditional Scania robustness to new levels and consolidates Scania’s reputation for low fuel consumption.
Scania continues to lead the way in meeting and exceeding emission legislation requirements and ensuring low fuel consumption. Since its original Euro 5 EGR engine platform was launched in 2007 (2010 in Australia), numerous refinements have been made to improve the intake and exhaust manifolds, EGR system, turbochargers, pistons and cylinder liners.
Liners, for example, are now plasma-coated for lower friction and extended service life.
Scania’s SCR (Selective Catalytic Reduction) after treatment systems have also been developed further.
Injectors for the urea solution have been upgraded to prevent clogging, and on the latest Euro 6 engine family, electrically controlled urea injectors further improve control in combination with an advanced exhaust management system.
The new engine platform comes with the latest versions of Scania Opticruise and Scania Retarder for even better uptime and productivity.
These engine refinements, in combination with dedicated service support, will enable Scania to provide its customers with complete solutions tailored to match their needs in any part of the world.
The new inline 5- and 6-cylinder engines share the same architecture and modular design, which was conceived for easy servicing and maximum uptime. The familiar engine architecture means that the products are recognised by service technicians worldwide, reducing the need for training.
The use of a common bore on the 9.3- and 12.7-litre engines means that a large number of cylinder parts and components are identical, significantly reducing the number of unique parts needed and facilitating repairs and parts supply.
Scania SCR six-cylinder engine range
Australian Scania customers have already had access to the 12.7-litre six-cylinder XPI EGR Euro 5 engine for some time, but now Scania adds a range of six-cylinder Euro 5 SCR engines, rated at 360 hp, 400 hp, 440 hp and 480 hp.
The SCR engine solution will be ideal for customers already using SCR systems on their other vehicles, for example Scania V8 engines, or for customers who would like a Euro 5 emission package combined with a low roof cab, such as the Scania P-series.
Scania will make three SCR six-cylinder engines available to P-series customers, bringing the 440 hp engine to the P-series for the first time.
In some cases the torque outputs of the Scania SCR six-cylinder family are higher than those of competitor engines of similar horsepower ratings:
• The 360 hp SCR engine produces 1850 Nm of torque
• The 400 hp SCR engine produces 2100 Nm of torque
• The 440 hp SCR engine produces 2300 Nm of torque
• The 480 hp SCR engine produces 2400 Nm of torque
The Scania EGR six-cylinder engines produce identical torque within the same 1000 rpm -1300 rpm green band as the SCR engines, with the exception of the 480 EGR engine, which produces 2500 Nm of torque.
In the new Euro 5 six-cylinder SCR engines a urea solution (AdBlue) mixed with air is injected into the exhaust flow in the silencer to reduce the formation of NOx (nitrogen oxides) to the required levels.
During the chemical reaction, ammonium and nitrogen oxides are converted to harmless nitrogen and water vapour. AdBlue is contained in a separate (75-litre) tank on the chassis. SCR allows combustion in the engine to be optimised for low fuel consumption, despite significantly lower emissions of hazardous substances.
“Scania Australia is very pleased to be able to offer its customers the option of an SCR six-cylinder engine range solution in 2012,” says Roger McCarthy, Managing Director.
“As a company we were aware of the variability of fuel quality in global markets and devised the SCR solution to be able to cope with these fuel differences.
“We therefore have created a Euro 5 solution for markets where there are high sulphur contents in fuel.
“We will of course continue to offer our EGR solutions in parallel to the SCR solution for customers who find the urea solution suitable for their needs.
“In particular, we are confident that for example, the availability for the first time of a 440 hp six-cylinder engine installed in the P-series cabs will have appeal to a wide variety of operators,” Roger says.
“This is particularly so for those who avail themselves of our 6x2 drive configuration which allows a higher payload thanks to weight saving provide by a single drive axle.”
