Scania announces 7.0-litre engines

Scania has introduced a new 7.0-litre engine which is the smallest truck engine Scania has offered in decades. Scania says the engines are ideal for urban and regional distribution applications.

As with the New Truck Generation range already launched in Australia, the new 7.0-litre models come as standard with steering wheel and side curtain rollover airbag protection, optimising driver and passenger safety.

Other features of the new trucks include quiet operation, smooth-riding suspension and in-dash weight scales readouts for each axle set.

“With our new engine family, we are widening the appeal of Scania’s product range to customers who have traditionally purchased lighter-duty trucks,” says Dean Dal Santo, Director of Truck Sales at Scania Australia.

“A key advantage is the 360kg reduction in tare weight (compared with the Scania five-cylinder 9.0-litre engine) and a significant reduction in fuel consumption. This combination will meet the growing requirement for sustainable transport by urban and regional operators in Australia.

“But the new format doesn’t mean we have made any concessions when it comes to typical Scania characteristics such as performance, robustness and uptime,” Dal Santo says. “These trucks offer all of Scania’s heavy-duty engineering, driveline efficiencies and safety benefits, optimised for lighter-duty roles, which are sure to draw new customers to the Scania family.”

“Scania’s 7.0-litre range also comes with our five-year/500,000km maintenance offer included with the purchase, a valuable and appealing operating costs bonus for operators,” Dal Santo said.

Scania’s Driver Services, fleet monitoring and aftersales contract maintenance are all offered with the 7.0-litre range.

The new inline six has been developed together with Cummins, Scania’s long-term partner in engine and component development. It has good low-rev, high torque characteristics and a fixed geometry turbocharger, and it uses only selective catalytic reduction (SCR) for the exhaust gas after-treatment to meet Euro 6 compliance.

“The Scania DC07 is based on a well-known and robust six-cylinder engine,” says Anna Wingren, Assistant Chief Engineer, Scania R&D.

“We’ve added Scania’s accumulated knowledge about advanced diesel engines, including our own technology and developed a Scania platform offering unparalleled characteristics for applications where a torque level of up to 1200Nm is required.”

Scania says the new engine will appeal to operators in urban and regional distribution, and civil and urban infrastructure maintenance. Weight is often a challenge in these types of applications and is also usually the main reason why these operators have bypassed Scania in the past.

The existing basic engine has been comprehensively developed. All of its monitoring and control systems are developed by Scania. In addition, it has been provided with a completely new turbocharger installation, and the new version uses Scania’s unique exhaust gas after-treatment system, developed in-house, with SCR-only, to reduce NOx emissions.

“There are around a hundred new parts in all, with some, such as the new flywheel housing, mainly involved in interfacing with Scania’s modular systems,” Anna Wingren says.

The new engine offers maximum torque from revs as low as 1050rpm up to 1600rpm. This provides very good driveability, we’re told, and, because of the low revs, the potential to save fuel.

“With its 3.07:1 final drive ratio, the engine is turning over at just 1600rpm at 100km/h,” says Dean Dal Santo.

“The fuel savings this will return on longer freeway journeys can easily be imagined, as will the increased driver comfort and reduced fatigue as a result of the lower levels of noise, vibration and harshness from intruding into the cabin.”

The ergonomic design of the dashboard and the controls mean everything is conveniently located. Large digital dashboard displays and a high-quality audio system, including digital radio and Bluetooth streaming and telephony, present a luxury car environment to the driver.

Both driver and passenger get air suspension seats, and the steering column adjusts for both rake and reach.

Compared with Scania’s well-known five-cylinder DC09 family – previously the first choice of many customers in the applications and type of operation that the DC07 is aimed at – the weight reduction is significant. This can amount to 360kg, which can be converted to payload, all things being equal. But according to Scania’s way of viewing things and optimising vehicles, there is nothing to prevent you from driving 26-tonne vehicles with the new 7.0-litre engine.

“We will continue to offer our proven and popular 9.0-litre engine in the P-series which is ideally suited to offering heavier twin-steer and 6x4 applications. The 7.0-litre will give us new strength in the lighter applications,” Dal Santo said.

“As a delivery specification truck, the 7.0-litre might start the day with a gross laden weight of 18-tonnes but will soon be down to 10- to 12-tonnes, after having made a few deliveries. We always strive to tailor the right solution for our customers, based on their actual needs.

Australian specification includes airbag suspension over the front and rear axle sets, which permit the adoption as a standard weight scale system that displays on the digital dashboard. This removes any possibility of drivers unwittingly being overloaded for their specific axle weight.
