LOUISVILLE, Ky. — Volvo Trucks today showcased its prototype D13-LNG engine, an integrated natural gas solution for the North American market.

The Volvo D13-LNG compression-ignition engine uses liquefied natural gas (LNG) to deliver increased range and significant fuel efficiency improvements compared with other natural gas-powered offerings. Customers will also be able to specify a Volvo I-Shift automated manual transmission. Volvo showed the prototype LNG solution in a Volvo VNL daycab during the 2013 Mid-America Trucking Show.

Volvo’s D13-LNG engine is a continuation of its comprehensive Blue Power natural gas strategy for North America, joining previously announced spark-ignited natural gas engine options for the Volvo VNM and VNL model daycabs.

The Volvo 13-liter compression-ignition engine, utilizing a small amount of diesel fuel to ignite the LNG, delivers diesel-like durability and performance in terms of horsepower and torque, according to Volvo.

The D13-LNG also provides about a 20 percent fuel efficiency improvement compared with spark-ignition natural gas engines and an even greater fuel cost reduction when compared with diesel-powered engines.

Volvo VNL daycabs powered by the Volvo D13-LNG engine will be available for order during the second half of 2014.
