Orders Will Be Taken Late This Year for Compression-Ignition Engine
Volvo Trucks will begin taking orders for its D13-LNG compression ignition natural gas engine later this year, with initial availability in 2015, says sales and marketing president Göran Nyberg.
“The D13-LNG engine is a compression ignition engine, rather than a spark ignition engine like the ISX12 G engine currently available in our VNL models or the ISL G offered in our VNM models,” he says.
At ACT Expo 2014 in Long Beach, Calif. last month, Volvo showed a CNG-fueled VNL 300 daycab tractor powered by the 11.9-liter Cummins Westport ISX12 G.
Volvo has worked with Westport on development of the new D13-LNG, and according to Nyberg expects to achieve diesel displacement of 95% for the new engine. Horsepower of up to 455 with 1,750-1,550 foot pounds of torque is promised.
Volvo also projects a 20% fuel efficiency improvement compared with spark-ignition natural gas engines for the liquefied natural gas product.
“Interest in natural gas-powered trucks continues to grow, and we’re working to address demand from all segments of the market,” Volvo Trucks director of specialty vehicles and alternative fuels sales development Frank Bio said in a release prior to ACT Expo.
Volvo Promotes DME Too
“Upon initial announcement of the project in 2012, we projected initial availability in 2014,” Nyberg notes.
Volvo also displayed a VNL 300 daycab fueled by dimethyl ether at ACT Expo. The company detailed a partnership for the diesel substitute with DME producer Oberon Fuels just one year ago (F&F, June 11, 2013). DME has handling properties similar to those of propane autogas – meaning it can be stored in cheaper onboard fuel tanks – and can be readily produced from renewable feeds.
