difference at a glance. The B16B sported twin SU HS4 carbs, notably larger than the B14A's HS2 carbs. Also, the remote oil filter attached next to the water pump on the ignition distributor side of the engine on the B14 had been relocated to a housing under the intake and exhaust manifold side on the B16. The exhaust manifold which dumped centrally on the B14 now was made to exit towards the rear of the B16 manifold. In automotive applications, the B16 was featured from 1957 to 1961 model years although in marine and industrial applications it was used for a number of years after. It was replaced in 1962 model year cars by the 5 main-bearing B18 engine of 1.8 litres which had been first seen by the automotive public in the 1961 Volvo P1800 sports car. With the discontinuation of the B16 also came the end of 6 volt electrical systems in Volvo cars. See also List of Volvo engines References B4B Straight-four engines Gasoline engines by model
