The F engine family from Mazda is a mid-sized inline-four piston engine with iron block, alloy head and belt-driven SOHC and DOHC configurations. Introduced in 1983 as the 1.6-litre F6, this engine was found in the Mazda B-Series truck and Mazda G platform models such as Mazda 626/Capella as well as many other models internationally including Mazda Bongo and Ford Freda clone, Mazda B-series based Ford Courier, Mazda 929 HC and the GD platform-based Ford Probe

There were four basic head types within the F range, the diesel SOHC 8-valve (R-series), the petrol SOHC 8-valve, petrol SOHC 12-valve, and the petrol DOHC 16-valve. These heads came attached to multiple variations of the different blocks and strokes. Only the petrol 8-valve and 12-valve shared the same gasket pattern. It was built at the Miyoshi Plant in Miyoshi, Hiroshima, Japan.
