Volvo B30 engine

The B30 is a Straight-six engine with overhead valves, produced by Volvo starting in 1968 and used primarily in the Volvo 164 sedan from 1969 through 1975. It was also used in the Volvo C303 military vehicle. Other applications include marine, industrial, and agricultural machinery and powercraft. Piston displacement is 2,978 cubic centimetres (182 cu in). The B30 was realised by adding 2 cylinders to the 4-cylinder B20 engine and many components are shared between the B30 and B20. Output ranged from 130 brake horsepower (97 kW) from the B30/B30A twin carburettor version to 160 brake horsepower (119 kW) from the higher-compression B30E fuel injection.
