The engine models are identified by the cylinder bore diameter in centimeters, which as of 2024 range from 20 to 46 centimetres (7.9 to 18.1 inches). The smallest engine series, Wärtsilä 20, produces a modest 200 to 220 kW (270 to 300 hp) per cylinder and is available in inline configurations from 4 to 9 cylinders.

The PA engines were high-speed units, running at more than 1,000 rpm. The initial PA1 and PA2 models could be seen as miniature versions of the PC engines, with a bore of 175 mm, and could be used for a wide range of applications – including powering submarines. The first turbo-charged version of the PA developed 46 kW per cylinder at 1,250 rpm
