Scania unveils P series with new engine


Lighter vocational truck and new 5-cylinder engine break cover

Scania unveils P series with new engine
The P-series, seen here in rigid mode, sports a 5-cylinder engine

 

Hot on the heels of the ‘new generation’ construction-focused XT range, Scania has let slip the covers on its new P-series rigid, again aimed mainly at Europe at this stage.

The P-series is also a vocational product but at the lighter end, with the truckmaker spruiking its flexibility, form rigid delivery or prime mover supermarket duties, to fire-fighting appliances to police rescue holdalls, waste/refuse applications, as well as, in Europe, lighter duty agitators.

As with all the new generation trucks, the Australian market must await confirmation of which models will come this way but it has struggled to make headway with lighter trucks.

In Europe, six different P-cab and three variants and three power outputs will be available, Scania says.

The cabs range from the CP14L with a low roof – "particularly suitable as a starting point to make room for highly productive and advanced bodywork that goes over the cab roof" – to the CP20H for those wanting comfortable interior spaces, a lower weight and lower boarding steps, with a cab that is mounted lower in relation to the vehicle’s chassis.

"While there isn’t evenly weighted demand for all the versions, for us at Scania it’s a matter of credibility to be able to offer the right variant for applications and requirements that are not so common, as well," Scania Trucks construction product director Anders Lampinen states.

"The entire Scania philosophy of always being able to offer the best total operating economy, thanks to customised solutions for all applications, is based on the diversity and customer benefit provided by the Scania modular system."

A new P-series with a low roof has the same roof height as a P-series from the PGR generation.

The new CP17N or CP20N provides a cab with 10 centimetres more interior headroom than previous versions. This is consistent with all of Scania’s new generation cabs where interior space has increased.

New Scania engine

Concurrent with the reveal of the new P-series cab is the unveiling of the revised and updated 5-cylinder engine family, though the P-series will be available with an array of 13-litre 6-cylinder engines.

Scania’s 5-cylinder 9-litre engine is introduced in Europe with three Euro 6-compliant power outputs – 280hp (209kW), 320h (239kW) and p and 360hp (268kW).

The new features consist of new engine software and a reconfigured combustion chamber.

Oil cooling is now thermostatically-controlled, with Scania stating this contributes a 1 per cent fuel saving, "since the oil can generally be allowed to maintain a higher working temperature. The cooling fan is fitted directly on the crankshaft and no energy-intensive upshifting is required." 

The Euro 6 DC09 engines now use a fixed geometry turbocharger (FGT) and the engines use only selective catalytic reduction (SCR) for exhaust gas after-treatment. 

"Scania has very good experience of combining a fixed geometry turbocharger and SCR for exhaust gas after-treatment," Lampinen says.

"These are energy-efficient, robust and highly reliable engines, which deliver the power in many construction and distribution vehicles day-after-day." 

Other efficiency modifications are a compression ratio increased from 18.0:1 to 19.0:1, cylinder pressure increased to a maximum of 190 bar or 180 bar for the 280 hp version, and a more efficient combustion chamber.

"With 1,700 Nm at 1,050 rpm, and rapid torque build-up from idle, the DC09 engine family is ideal for distribution or construction or special vehicle applications," Scania says.

"The DC09 family shares its technology and design with its 6-cylinder siblings in the DC13 family in all material respects.

"Its balance shafts and the introduction of an asymmetric crank pin pitch (ACPP) counteract the typical tendency of 5-cylinder engines to vibrate, so that it now runs just as smoothly and silently as a 6-cylinder engine. 

"Its natural market is those customers requiring power, robustness and low consumption, but who for reasons such as weight do not want to go to a 6-cylinder engine."
