Volvo also updated its 11-liter D11 and standard 13-liter D13, already two of the industry's most fuel-effi cient engines. Wade Long, director of product market- ing for Volvo Trucks North America, says the engines feature a proven common-rail fuel system for reduced engine and cab noise, providing drivers a more comfort- able ride. The common-rail fuel system also contributes to fuel effi ciency im- provements through fi ner control of the fuel injection, allowing for quicker, more accurate injection and a more effi cient way to control fuel pressure, Long adds. An updated EGR fl ow sensor has a new double-wall casing that reduces condensa- tion and soot buildup in cold weather, preventing downtime, Volvo says. A low-pressure fuel system features an im- proved aftertreatment dosing module that is integrated into the fuel fi lter housing for easier serviceability. Upgrades to the two-speed coolant pump for both engines also improve fuel effi ciency as a result of reduced parasitic losses. The new intake throttle enables a faster warmup when the engine is started. The 2017 Volvo D11 offers up to 425 horsepower and 1,550 lb.-ft. of torque, an increase of 20 horsepower. The engine also delivers up to a 2.2 percent fuel ef- fi ciency improvement compared with the previous D11 engine, Long says. Designed for regional, less than truckload (LTL) and pickup-and- delivery applications, the D11 is available in Volvo VN daycabs, VNM 430 and VNL 430 sleeper models, VAH and VHD models. D11 production is expected to begin in January of next year. The 2017 Volvo D13 and D11 feature a new wave piston, which increases the compression ratio, Long says, from 16:1 to 17:1 and maximizes fuel effi ciency. Im- proved fl ame propogation reduces soot, while also increasing cylinder effi ciency. The updated D13 – Volvo's most popular engine – is available in the Volvo VN, VHD and VAH models, and offers a fuel effi ciency improvement of up to 2.5 percent compared to the previous D13. These engine enhancements were also included in the 2017 Volvo D13 with turbo compounding. Production on the D13 is expected to being October 2016. Volvo's D16, which get no major updates, will begin production in January 2017. Volvo closed 2015 with almost 93 percent of its trucks spec'd with Volvo power, Nyberg says.
