Volvo Trucks Unveils New Powertrain Featuring Increased Power and Fuel Efficiency3/22/2016
Volvo Trucks North America today launched several new integrated powertrain solutions, offering increased fuel efficiency, productivity, reliability, packaging, comfort and uptime. Integral to the new powertrain are enhanced design features that were engineered to provide Volvo customers best-in-class performance, productivity, fuel efficiency and an improved total cost of ownership.
Volvo's new powertrain offerings include multiple engine enhancements, such as turbo compounding for the Volvo D13 engine; the introduction of Volvo I-Shift with Crawler Gears automated manual transmission; and a one-box Exhaust Aftertreatment System (EATS). The technology improvements deliver on Volvo's commitment to drive integrated powertrain development to meet the various needs of customers in a full range of applications, bringing outstanding power, performance and efficiency.
"Volvo has long been a leader in offering integrated technologies that meet and exceed our customers' expectations for fuel efficiency, power and performance," said Gӧran Nyberg, president of Volvo Trucks North America. "These new Volvo powertrain enhancements incorporate our innovative engineering and technology expertise with our focus on meeting customers' needs to offer them the best possible solutions for the best possible return on investment."
Volvo Engine Enhancements
For the first time in North America, Volvo's 2017 D13 engine will be available with turbo compounding, a technology that recovers wasted exhaust heat and converts it to useable mechanical energy that is transferred back into the engine. The result of this recovered energy is up to a 6.5 percent improvement in fuel efficiency compared with previous engine models. Applications that benefit most from turbo compounding include long-haul, steady-state driving.
In another first, Volvo's XE – eXceptional Efficiency - powertrain package with the D13 turbo compounding engine will be available to customers desiring to run in top gear in states and provinces that have 55 mph speed limits. Through downspeeding, XE allows the engine to cruise at up to 300 rpm less than the average truck sold today – significantly improving fuel efficiency. More than 27 percent of all Volvo models sold in 2015 featured an XE package.
Volvo's 2017 11-liter D11 engine and the 2017 D13 both received numerous updates designed to improve fuel efficiency. The updates include: a proven common-rail fuel system that reduces engine and cab noise, while optimizing fuel delivery; an available two-speed coolant pump that reduces parasitic loss; and redesigned pistons for greater combustion efficiency.
These improvements boost D11 to up to 425 horsepower, while improving fuel efficiency by up to 2.2 percent. The 2017 D13 will see up to a 2.5 percent improvement in fuel efficiency.
Volvo I-Shift with Crawler Gears
Offering vocational and highway customers improved startability and maneuverability, Volvo today launched the I-Shift with Crawler Gears automated manual transmission (AMT). Designed with crawler functionality and startability, I-Shift with Crawler Gears is ideal for applications requiring a slow speed and maneuverabilty – applications such as concrete mixers with curb-pouring capability, asphalt paving, spreaders, dump trucks, heavy haul and line painters. The I-Shift with Crawler Gears also ensures startability for heavy haul and up to 220,000 lbs. GCW or more with application approval.
I-Shift with Crawler Gears will be available in two versions:
- 14 forward gears, including one low crawler gear (19.38 gear ratio) and one ultra-low crawler gear (32.04 gear ratio), which can operate down to 0.6 mph with 3.58 rear axle ratio
- 13 forward gears, including one low crawler gear (17.54 ratio).
Available as an overdrive in Volvo VHD, VNX, VNM and VNL models, the I-Shift with Crawler Gears can be spec'd with Volvo D11, D13 and D16 engines.
In addition, all I-Shift models, spec'd in a record 83 percent of Volvo-powered vehicles in 2015, received revised hardware for increased durability, including an upgraded countershaft for faster shifting and improved performance.
I-Shift efficiency also received a boost from the Volvo I-See system, which works in tandem with the I-Shift transmission. Launched in North America by Volvo today, I-See is a new feature which learns the topography of the road, memorizes it and stores it in the transmission for use the next time the driver travels the routes. The system stores up to 4,500 different hills.
The built-in electronics constantly monitor factors such as road grade, speed, weight and engine load to help maintain the most efficient gear possible. When the truck is operational, it automatically uses its knowledge to save fuel during the driving cycle. It optimizes gear shifting on rolling hills and hilly terrain. I-See handles hills efficiently by building speed before the hill, then curbs speed before the crest, Eco-Rolling down the hill and engine braking if necessary.
"Rugged jobs require durable equipment that can stay ahead of the pace," said John Moore, Volvo product marketing manager – powertrain. "The integration between the transmission and the engine is critical to getting the best performance and efficiency possible. Drivers are now going to get more power for less fuel spent."
I-Shift is a key component to Volvo's XE powertrain package. The inclusion of the new I-Shift with Crawler Gears in the XE Adaptive Gearing package expands the capabilities of XE from 80,000 lbs. up to 110,000 lbs. GCW as the low gear ratios maintain startability and enhance slow speed performance on softer ground.
One-Box Exhaust Aftertreatment System
Volvo today introduced a new one-box exhaust aftertreatment system (EATS) that combines the diesel particulate filter (DPF) with the selective catalytic reduction (SCR) and diesel exhaust fluid doser into a single unit. The system also features a new copper-zeolite coating that improves low temperature NOx conversion for improved emissions.
The new design configuration results in better thermal performance for improved efficiency, smaller packaging requirements and an approximately 17-pound weight reduction compared with the two-box unit. This provides additional frame rail space for added packaging flexibility.
The new one-box EATS will be standard on the D11- and D13-equipped powertrains. The two-box solution will remain on the D16.
Vehicle Uptime Through Remote Diagnostics
Vehicle uptime is a critical factor for drivers and fleet managers, which is why Volvo is dedicated to ensuring new technology helps maximize time on the road through Volvo Remote Diagnostics. Remote Diagnostics is a telematics-based proactive diagnostic and repair planning system that monitors critical engine and I-Shift fault codes.
When an issue is detected, the system identifies what parts will be needed and provides technicians with straightforward repair instructions – even before the truck arrives for service. Remote Diagnostics can reduce the diagnostic time by up to 70 percent and lower repair time by more than 20 percent.
Remote Diagnostics has been standard on all Volvo-powered models since 2013. Remote Diagnostics is a central component of Volvo's uptime services, which also include 24/7 support, Volvo Action Service, and ASIST, Volvo's service management platform.
Volvo Trucks today introduced several new integrated powertrain solutions, offering increased fuel efficiency, productivity, reliability, packaging, comfort and uptime. In addition to updates to the Volvo D11, D13 and D16 engines and the I-Shift, Volvo introduced the new D13 engine with turbo compounding (left), a new I-Shift with Crawler Gears automated manual transmission (right), I-See cruise control technology and a new one-box exhaust aftertreatment solution.
