Volvo SI6 engine
The SI6 (Short Inline 6) is a family of straight-six engines developed by Volvo and used by Land Rover and Volvo. HistoryVolvo designed the SI6[3] ("short inline 6") straight-six automobile engine for use in 2007 models. An evolution of the company's long-used straight-five Volvo Modular engine, which itself is an evolution of the Volvo B6304 straight-six engine, the SI6 can be mounted transversely for front wheel drive or all wheel drive applications. Despite the added cylinder and displacement, the engine remains compact, and is in fact 1 mm (0.039 in) shorter than the previous straight-five. The engine was initially offered in two displacements — a 3.0 L turbocharged version and a 3.2 L naturally aspirated version. Both offered variable cam timing, though only the turbo version varies both the intake and exhaust valves. On top of the variable cam timing used on the intake cam of the naturally aspirated engine it also had variable valve lift by using Cam Profile Switching (CPS). Production of the Volvo SI6 began at the Ford Bridgend Engine Plant in Wales in May 2006. It was assumed that the engines would be used in European Ford and Jaguar products as well as Volvos.[4][5] NomenclatureThe engine codes consist of a series of letters and digits:
Engine codes are not necessarily unique to a specific engine as power levels can vary depending on market, manufacturer and model. 3.0The 3.0 L (2,953 cc) straight-six engine is intercooled and turbocharged. Cylinder bore and stroke are 82 mm × 93.2 mm (3.23 in × 3.67 in) with a compression ratio of 9.3:1. B6304T2The B6304T2 has a power output of 210 kW; 281 hp (285 PS) at 5600 rpm, and produces 400 N⋅m (295 lb⋅ft) of torque at 1500–4800 rpm. Applications:
B6304T4The B6304T4[8] has a power output of 224 kW; 300 hp (304 PS) at 5600 rpm, and produces 440 N⋅m (325 lb⋅ft) of torque at 2100–4200 rpm.[9] Applications:
B6304T5The B6304T5 has a power output of 260 kW; 350 hp (350 PS) at 5250 rpm, and produces 500 N⋅m (369 lb⋅ft) of torque at 3000–4750 rpm.[10] Applications:
3.2The 3.2 L (3,192 cc) straight-six engine is naturally aspirated. Cylinder bore and stroke are 84 mm × 96 mm (3.31 in × 3.78 in) with a compression ratio of 10.8:1. B6324SThe B6324S has a power output of 175 kW; 235 hp (238 PS) at 6200 rpm, and produces 320 N⋅m (236 lb⋅ft) of torque at 3200 rpm.[12] Applications:
