Trade Trucks AU  /  November 8, 2016

Engine manufacturer Cummins South Pacific has announced it will release its X15 Euro 5 next generation heavy-duty engine for the truck market in 2017.

Replacing the 15-litre ISXe5, the new engine will be offered with the same horsepower ratings as the previous generation, from 450 to 600hp, and generate peak torque spanning 1,650 to 2,050 lb-ft.

However, the X15 will add Advanced Dynamic Efficient Powertrain Technology (ADEPT) and Connected Diagnosis to the hardware and SCR technology found in the ISXe5.

"The X15 uses the same hardware and emissions reduction technology – SCR – as the existing ISXe5," Cummins South Pacific managing director Andrew Penca says, "and incorporates all the product improvements since the ISXe5 release in 2012, including power cylinder, cylinder head and turbocharger upgrades."

The addition of the ADEPT offering, which has been trialled in Australian conditions since early this year and works with Eaton’s 18-speed automated UltraShift Plus transmission, will improve fuel economy as it "utilises load, speed and grade-sensing technology to initiate adjustments to engine power, torque and transmission gear selection to take advantage of vehicle momentum," Cummins says.

These improvements will be provided through two new features in the first ADEPT package: SmartCoast and SmartTorque.

The former disengages the front box of the transmission, returning the engine to idle, while a truck is travelling a moderate downhill grade to reduce drag, maintain momentum and reduce fuel consumption.

The gears are reengaged once the engine commands the transmission to be put back into action.

SmartTorque on the other hand is about focusing on a fuel-efficient ‘sweet spot’.

Using torque management intelligence to help remove unnecessary downshifts, Cummins says it keeps the engine running at its most efficient.

The other major addition is the introduction of Cummins Connected Diagnosis, a telematics system that provides detailed information and expert advice to the operator should a fault occur.

The automated process sends notifications from Cummins, via email, an app or the web portal, detailing probable root causes and the next steps an operator should take.

Cummins says this offering will be bolstered "in the near future" with the addition of Over-the-Air (OTA) engine programming and customisation.

The technology will allow engines to be reprogramed or updated without a visit to a service bay.

Those waiting for predictive cruise control will not have to wait much longer either, as Cummins says it will join the ADEPT offering in the future.

While it is slated for next year, industry sources believe the new X15 will make its first public appearance before then, arriving with an exciting new Kenworth model set for release in the next few months and scheduled to begin production at Kenworth’s Victorian Bayswater plant in February.

Cummins Australia announces new X15

Power Torque Magazine  /  November 2016

Cummins devotees have a new choice for their preferred engine options in 2017 as Cummins Australia has announced its replacement for the ISXe5, Australia’s largest selling engine in the heavy duty truck segment,

The Cummins X15 Euro 5 will be offered by the North American manufacturers that currently install the ISXe5 as an evolutionary product for Kenworth in the T-Series, the Argosy and Coronado from Freightliner and as the alternative engine to Detroit in Western Star products.

“The X15 uses the same hardware and emissions reduction technology – SCR – as the existing ISXe5, and incorporates all the product improvements since the ISXe5 release in 2012, including power cylinder, cylinder head and turbocharger upgrades,” says Andrew Penca, managing director of Cummins South Pacific.

“The X15 features ADEPT technology – a suite of advanced electronic features capable of delivering fuel economy gains through improved powertrain integration.

“Another feature to be released with the X15 is Connected Diagnostics, a telematics solution that delivers instant and expert diagnosis of engine faults to the customer.”

ADEPT – Advanced Dynamic Efficient Powertrain Technology – is for use with Eaton’s 18-speed automated UltraShift Plus transmission and has been under field test in Australia since early 2016.

It utilises load, speed and grade-sensing technology to initiate adjustments to engine power, torque and transmission gear selection to take advantage of vehicle momentum for better fuel economy. Also included is the Cummins Intebrake which provides engine braking of 600hp at 2100rpm.

The first ADEPT package includes two features: SmartCoast and SmartTorque.

SmartCoast operates when the vehicle is on a moderate downhill grade by disengaging the front box of the transmission and returning the engine to idle to reduce drag, maintain momentum, and ultimately improve fuel economy. Once the engine commands the transmission to be put back in gear, the appropriate gear is engaged.

SmartTorque uses torque management intelligence to help eliminate unnecessary downshifts and keep the engine operating in the most fuel efficient ‘sweet spot’. Torque is varied across all gears depending on torque requirement.

For Australian operating conditions, the torque varies up to 1850 lb ft or 2050 lb ft depending on the horsepower and peak torque rating of the engine. Further features such as predictive cruise control will be added to ADEPT in the future.

Cummins Connected Diagnostics will also be available with the release of the X15 in 2017. This telematics system automatically processes fault code data, sending instant notifications from Cummins to the vehicle fleet manager detailing the probable root cause and providing recommended actions.

The expert advice, delivered by email, app or web portal, enables the fleet manager to make an informed decision about continuing truck operation and when to schedule a service visit for the most convenient time, thus minimising downtime.

Additional connected solutions to be added in the near future include Over-the-Air (OTA) engine programming and customisation. This will allow an engine to be reprogrammed or updated with the latest calibration without having to take the truck to a service bay.

“The X15 builds on the success of the ISXe5 of which more than 6000 have gone into service in Australia and New Zealand since 2013,” says Mike Fowler, director of on-highway business for Cummins South Pacific. “During this time our 15-litre Euro 5 product has established class-leading reliability, fuel economy and performance.

“Our product development is no longer driven by emissions, but is instead inspired by customer needs and application requirements. The X15 is a sign of what is to come from Cummins in terms of significant efficiency gains for our customers.”

The X15 will be offered with the same ratings as the ISXe5, from 450 to 600 hp with peak torque spanning 1650 to 2050 lb ft.

Cummins chooses Valvoline

Big Rigs  /  November 17, 2016

Cummins' 15-litre ISXe5 on-highway engine now has oil drain intervals of up to 60,000km thanks to the recently released Valvoline Premium Blue 8100 oil.

Cummins announced the release of the new Valvoline Premium Blue 8100/7800/7700 diesel engine oil range, saying it has been updated to meet the latest Cummins Engineering Standard approvals and global oil registration process, and include a new technology formulation specially designed for Cummins engines.

The extended oil drain intervals require the use of Fleetguard's fuel filter and its patented nanonet technology for oil filtration.

"The extended oil drain intervals further support our focus on delivering industry-leading total cost of ownership with the ISXe5," said director of on-highway business for Cummins South Pacific Mike Fowler.

The announcement of the extended oil drain intervals for the Australian and New Zealand markets follows the most extensive oil validation field testing ever carried out by Cummins Inc.

The project began in November 2014 and included over 12 months of field testing and over seven million kilometres.

The new product brand names have been introduced to reflect the Cummins Engineering Standard number applicable to each oil and further demonstrate Premium Blue as 'The Only One' Cummins recommends and endorses for its engines.

"We wanted to ensure that any new lube oil product release would be thoroughly tested and validated to truly understand performance benefits for our customers," said Mike Fowler.

New Cummins engines set for Oz

Big Rigs  /  January 18, 2017

Cummins has announced its engine line-up for 2017.

The new X15 will hit our shores in Kenworths from January and in the new International shortly after.

The first release X15 will have Euro V emission ratings although the Euro VI version will become available after its launch at the Brisbane Truck Show in May.

Physically the X15 is the same as the current ISXe5 utilising the SCR/AdBlue emissions control system.

The changes come with the ADEPT technology, a game changer according to Cummins with a "suite of advanced electronic features capable of delivering fuel economy gains through improved powertrain integration”.

As telematics become more integral to transport operations, the X15 has what Cummins describes as Connected Diagnostics, a system that delivers real-time diagnosis of engine problems to Cummins and fleet operations by automatically processing fault code data and sending real-time notifications from Cummins detailing probable root causes of issues and providing recommended actions.

The expert advice, delivered by email or web portal, enables the fleet manager to make an informed decision about continuing truck operation and when to schedule a service visit the most convenient time.

ADEPT, or Advanced Dynamic Efficient Powertrain Technology is for use with Eaton's 18 speed automated UltraShift Plus transmission and has been under field testing in Australia since early 2016.

It utilises load, speed and gradient sensing technology to initiate adjustments to engine power, torque and transmission gear selection to take advantage of vehicle momentum for better fuel economy.

The first release of ADEPT in Australia will have SmartCoast and SmartTorque.

SmartCoast, like similar European product, disengages the front box of the transmission virtually putting the truck into angel gear while the engine remains at an idle while on a downgrade.

SmartTorque eliminates unnecessary downshifts and keeps the engine in the most fuel-efficient RPM range. Torque is varied across all gears depending on the power demand.

Mike Fowler, director of on-highway business for Cummins South Pacific said "the X15 builds on the success of the ISX e5 of which more than 6000 have gone into service in Australia and New Zealand since 2013”.

With the Euro six engine now fully developed, Fowler said engine development is not driven by emissions, but by customer needs.

Oz trials continue

FIELD testing of the Chinese built Cummins 12 litre engine continues through the summer, with trials in the heat of the nations outback roads.

Under the name of ISG, the engine was launched at the 2015 Brisbane Truck Show with a main claim to fame of its low weight, with an engine mass of 860kg.

The same engine under X12 branding is being built in the US for the North American market.

In an American media release, Cummins said the X12 will be rated up to 475hp with "the highest power to weight ratio in the 10 to 16 litre class”.

The current direction in the US is for a reduction in power, an increase in torque for the ultimate in fuel efficiency particularly in the giant high volume fleets.

We believe the X12 will fit easily into the new International ProStar, however Kenworth will not be taking the smaller capacity engine preferring Paccar's own engine with Euro ancestry and similarly Western Star will probably be using the company's global engine in this rating.

Both the X15 and X12 will go on sale in Australia with SCR managed Euro V standard with the SCR / EGR hybrid ready for Euro VI whenever the Australian market demands it.

The Brisbane Truck Show will undoubtedly reveal the future for Cummins, with these engines on display and, Big Rigs is told, flagging the Euro VI models for the future.
