From Ford Wiki

Volvo Cars has a long reputation as a maker of reliable Straight engine.

When Volvo started in 1927 they ordered the engines from the engine manufacturer Volvo Penta in Skövde. The first engine was the four cylinder side valve 28 hp Type DA. In 1931 Volvo acquired a majority of the Penta stock and in 1935 Penta became a subsidiary of Volvo.

The present owner Ford Motor Company has allowed Volvo to continue to design their own engines, with a new-generation Straight-6 introduced in 2006.

Naming

Volvo has used three systems to name their engines:

• 1955–1985 — four or five characters
• 1985–1994 — five or six characters
• 1993–1994 — six to eight characters

Generally, the following naming scheme is used:

• B for Bensin (gasoline/petrol) or D for Diesel
• Two digits for engine displacement (moved after number of cylinders from 1993)
• One for valves per cylinder (not found before 1985)
• One to three characters for engine features
