A new look at GAS

摘要

Volvo's FH and FM LNG (liquefied natural gas) tractors draw on the Volvo G13C LNG engine for performance on par with standard diesels with the same power rating, but emitting 20% less CO_2. From the head gasket down, Volvo's G13C LNG engine is based on its 12.8-litre, D13K Euro VI diesel power plant. Available in 414 and 454bhp outputs, with 2,100Nm and 2,300Nm of torque respectively, the G13C can be fitted to FM and FH models. Designed for heavy long-haul and distribution operations, the G13C is a 454bhp, 12.8- litre, in-line six-cylinder gas engine equipped with an overhead camshaft, four valves per cylinder and common rail fuel injection. Gas engines like the G13C460, with the diesel principle, can achieve higher horsepower and torque by using direct injection and relying on heated compression for ignition. Therefore the principal characteristics are similar to a diesel engine.
