1 PRESS info P13304EN / Per-Erik Nordström 21 March 2013 Second-generation Euro 6 with lower fuel consumption Scania introduces new Euro 6 engines with features that further boost efficiency. Second-generation 450 and 490 hp Euro 6 engines provide fuel savings of up to 2 percent. A unique, SCR-only 410 hp six has an extra economic edge. New 520 and 580 hp Euro 6 V8s provide exceptional performance and character. Proven EGR and SCR technologies are combined to provide optimum performance in all market segments. The Euro 6 emission standard calls for a fine balance between the combustion and aftertreatment processes. Scania is using its vast experience of both EGR and SCR to implement an optimal technical solution for each output level, as well as for individual applications. Scania customers now have a choice of nine Euro 6 outputs, ranging from the 250 hp 9-litre unit to the 580 hp V8. Additional outputs will follow. In addition there are two gas engines, adaptable to run on biogas, compressed natural gas (CNG) or liquefied LNG. V8s with exceptional torque The only Euro 6 V8s in the market, the new engines are based on the 16.4-litre platform introduced with the 730 hp unit. They have typical Scania V8 traits, with plenty of lugging power from low down the rev range. Like Scania's inline 13-litre engines, the new V8s have torque-to-power ratios in excess of hp, 2,700 Nm at 1,000-1,300 r/min, EGR+SCR 580 hp, 2,950 Nm at 1,000-1,350 r/min, EGR+SCR 730 hp, to be released later The performance of the new 580 hp Euro 6 V8 is similar to the 620 hp Euro 5 thanks to its wider torque peak and fat power curve. Fuel consumption of a Euro 6 V8 engine worked hard is equivalent to Euro 5. The exhaust brake output is 320 kw at 2,400 r/min. Scania Corporate Relations Telephone SE Södertälje Fax Sweden
2 2 (11) 16-litre 520 hp V8 16-litre 580 hp V8 Scania's Euro 6 V8 engines feature common-rail fuel injection (Scania PI) and a variable-geometry turbocharger (VGT) mounted at the rear. A newly-developed water-cooled EGR system is fitted low down underneath the RH cylinder bank. The silencer unit for the V8 engines is somewhat larger with higher capacity than for inline engines. The top-output 730 hp V8 is due for release by the time Euro 6 becomes mandatory. Further refined 6-cylinder engines Four 12.7-litre engines constitute Scania's six-cylinder Euro 6 offering. 370 hp, to be released later 410 hp, 2,150 Nm at 1,000-1,300 r/min, SCR (see below) 450 hp, 2,350 Nm at 1,000-1,300 r/min, EGR+SCR 490 hp, 2,550 Nm at 1,000-1,300 r/min, EGR+SCR The 450 and 490 hp engines are based on further refinements of the 440 and 480 hp units, which have been proven in the hands of operators since early The 450 hp engine is available in P-, G- and R-series and the 490 hp unit in G- and R-series trucks.
3 3 (11) The 450 and 490 hp engines have been further developed in several respects, including the engine management system and a revised intake system that maintains sufficiently high exhaust temperatures without the need for an intake throttle. The exhaust brake is rated at 256 kw at 2,400 r/min. A new disengaging air compressor is being introduced across the Euro 6 engine range. The compressor has a pneumatically-controlled coupling that disengages when the compressor is idling, contributing to a fuel saving of up to 1 percent, depending on operation. Euro 6 trucks for long-haulage should generally be specified for highway cruising at less than 1,200 r/min to minimise fuel consumption. The high torque delivered already from low revs in combination with automated gearchanging means that the low cruising revs save fuel without requiring extra attention from the driver. Tests have shown that Scania's second-generation Euro 6 engines are 2-3 percent more economical than the first ones. 13-litre 410 hp six 13-litre 450 hp six 13-litre 490 hp six 410 hp fuel-saver with only SCR The 410 hp engine has been developed to manage Euro 6 using only SCR technology. A fixed-geometry turbocharger and an electric intake throttle are used. Without EGR piping, the auxiliary systems are somewhat simpler and there is a weight saving of 40 kg compared to an engine with EGR and SCR, some of which is likely to be used to carry more AdBlue on-board. The exhaust aftertreatment system remains unchanged, with the same compact silencer unit as for other 5- and 6- cylinder Euro 6 engines. The 410 hp 13-litre produces maximum torque all the way down to 1,000 r/min. The engine is around 3 percent more economical than the 400 hp Euro 5 EGR engine. AdBlue consumption of Scania's Euro 6 engines with only SCR is limited to around 6 percent of diesel consumption. The corresponding figure for an engine with EGR and
4 4 (11) SCR is around 3 percent or somewhat higher at very high load, high altitude or in cold weather. 5-cylinder Euro 6 engines The range presented at IAA 2012 comprises four diesel engines and two gas engines, with an ethanol engine in the pipeline. 250 hp diesel, 1,250 Nm at 1,000-1,350 r/min, EGR+SCR 280 hp diesel, 1,400 Nm at 1,000-1,350 r/min, EGR+SCR 320 hp diesel, 1,600 Nm at 1,050-1,300 r/min, SCR 360 hp diesel, 1,700 Nm at 1,100-1,350 r/min, SCR 280 hp gas/biogas, 1,350 Nm at 1,100-1,400 r/min 340 hp gas/biogas, 1,600 Nm at 1,100-1,400 r/min, 280 hp ethanol, to be released later The 320 and 360 hp 9-litre engines with only SCR are optimised for cruising at higher revs and can be geared for economical cruising between 1250 and 1350 r/min. The exhaust brake produces 190 kw at 2,400 r/min. Exhaust temperature important for Euro 6 For applications where engines seldom run at full load, Scania recommends that customers consider going for a somewhat lower engine output than for Euro 5. Working the engine a little harder will benefit efficiency, since a high exhaust temperature can be maintained more easily. If the exhaust temperature is getting too low, extra fuel will be burnt to keep the aftertreatment system working properly. Similarly, leaving the engine idling will risk cooling down the aftertreatment system. Aftertreatment principles The equipment on the engine varies between engines with EGR+SCR and engines with SCR only. An electrical intake throttle is used on 250, 280, 320, 360 and 410 hp engines, whereas the new 450 and 490 hp 13-litre engines and 520 and 580 hp V8 engines manage without it. For extra heat management, the two 9-litre engines with EGR and SCR have an extra injector to spray diesel into the exhaust.
5 5 (11) Scania Euro 6 technologies The upstream NOx sensor, diesel oxidation catalyst (DOC), full-flow diesel particulate filter (DPF), AdBlue mixer, parallel SCR catalysts, ammonium slip catalysts (ASC) and downstream NOx sensor are all integrated in the silencer unit. The temperature ( C) is measured all the way up to the catalysts and the pressure drop (ΔP) across the DPF monitored to assess the status of the filter. The aftertreatment system contained in the silencer unit is modularised and the same size for all inline engines. The V8 unit is 270 mm longer, containing two parallel particulate filters and three parallel SCR and ammonium slip circuits. How much AdBlue do you need to carry? For extra flexibility in terms of autonomy and fuel capacity, Scania is introducing a new range of AdBlue tanks. One series is mounted in a hidden position on the inside of the LH frame member, leaving space along the side for extra fuel or other equipment. Side-mounted AdBlue tanks: 30, 60 and 90 litres net
6 6 (11) Hidden AdBlue tanks: 58 and 100 litres net, and 60 litres net for extra low chassis The wide range of tank sizes allows the operating range to be adapted to the diesel tank capacity or to the technology at hand (EGR+SCR or SCR only). Global engine range Scania customers have access to the same global engine range for different emission levels. All Scania engines are tuned to provide generous torque from 1,000 r/min or below. This allows the overall gearing to be chosen for maximum fuel economy below 1,200 r/min for most types of long-haulage (except 320 and 360 hp Euro 6, see above). The high torque ratings ensure that hills can be climbed with a minimum of gearchanging.

Euro 3, 4, 5 and EEV engines can be operated on up to 100 percent biodiesel. Scania is also developing some of its Euro 6 engines for 100 percent biodiesel, details of which will be released later. Gas/biogas and ethanol engines complying with Euro 5/EEV are available, two Euro 6 gas engines were introduced at the IAA 2012 exhibition in Germany and an ethanol engine will follow later. Conversions for liquefied gas are available.
7 7 (11) LATEST UPTIME-BOOSTERS Innovative Scania-designed dual-battery system Well-functioning electrics are a prerequisite for high uptime. To reduce the risk of inadvertent discharging or battery failure, Scania has developed a new system with two sets of batteries that safeguard electric supply for starting. The 24 V dual-battery system is mainly intended for applications with high electricity consumption, but provides uptime insurance for all transport types. Instead of the traditional setup with two 12 V batteries connected in series, the dualbattery system consists of four maintenance-free batteries of two markedly different types. The two AGM-type (absorbed glass mat) starter batteries are optimised for delivering high starting power during a short time. They are kept fully charged at all times and are used exclusively for starting. The two gel-type service batteries are suitable for deeper discharge cycles. They supply all of the truck s power consumers lights, bodywork functions, heating, etc. which are thus kept entirely separate from the starter circuit. The entire four-battery set-up with two types of batteries is more compact than a conventional 2-battery system. In most cases, the set-up can be housed in the normal battery box on the LH side of the chassis. The new dual-battery system is a unique Scania design that differs from a conventional dual-battery set-up in the use of two different battery types that are optimised for different purposes and have a specially-developed control system. New hill-hold for drum brakes Hill-hold is a much appreciated feature that has been available in combination with electronically controlled brakes for several years. Especially popular with Scania Opticruise with automatic clutch, its availability is now being extended to include drum-braked 6x4, 8x4 and 8x8 vehicles.
8 8 (11) With disc brakes With drum brakes Activated with a switch, hill-hold is active for 3 seconds after the brake pedal has been released, allowing sufficient time to pull away without drama even on steep gradients. Hill-hold has been found to markedly reduce clutch wear on trucks that are subject to frequent hill starts, reducing the risk of costly downtime and repairs for the operator. Stronger single-drive rear axle The new strong single-drive rear axle (R855) with disc brakes has been designed for high gross weights and demanding topography, such as mountainous trans-alpine, trans-andean or Norwegian routes, where the load is high going both uphill and downhill using the retarder. Ratios: 2.87, 3.09, 3.23, 3.42, 3.64 and Increased robustness provides gains in uptime, while eliminating the need for hub reduction in some applications.
