Volvo Trucks plans to launch its own 13-liter liquefied natural gas (LNG) engine for North America in 2014. The engine’s advanced high pressure diesel ignition technology will provide significant fuel efficiency gains. Combined with the company’s previously announced offering of compressed natural gas (CNG)-powered Volvo VNM and VNL model daycabs, the new engine will provide customers with a complete range of natural gas-powered transportation solutions. Volvo is also testing another fuel that can be produced from natural gas, DME (dimethyl ether), which has the potential to become an attractive alternative for the North American market. 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.
