Through advanced high pressure diesel ignition technology – using trace amounts of diesel to ignite the natural gas – Volvo’s LNG engine will deliver a 30 percent fuel efficiency improvement compared with spark-ignition (SI) engines, making it a viable alternative for demanding long-haul applications. The Volvo 13-liter LNG engine will also reduce greenhouse gas emissions by about 20 percent compared with current diesel products.
The engine will accomplish these savings without sacrificing power, torque or fuel efficiency, all of which are critical attributes for on-highway operations. The Volvo Group was the number one supplier of 13-liter heavy-duty engines to the combined U.S. and Canadian market last year, and the same vertically integrated approach that has made Volvo a global powertrain leader is being applied to the development of the new engine.
