Mazda F engine
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.
These engines are only the predecessors to the F-series engines, in no other way related. They were fitted to rear-wheel drive models in a longitudinal arrangement. This is in contrast to the successor engines that were designed for transverse front-wheel drive applications as had become the trend in the late 1970s and early 1980s.
The VC is a 1.8 L (1,769 cc) overhead camshaft inline-four, with a bore and a stroke of 80 mm × 88 mm (3.15 in × 3.46 in). It was all new in 1975 (pre-1975 1.8 Couriers got the earlier, long-stroke VB engine) and has an alloy eight-valve head on an iron block. Output varied considerably depending on market and installation, in a 1981 UK-market B1800 it is 84 hp (63 kW; 85 PS) DIN at 5000 rpm and 13.7 kg⋅m (134 N⋅m; 99 lb⋅ft) at 2500 rpm.
Applications:
The 2.0 L (1,970 cc) was designated MA. Bore was as for the VC, 80 mm (3.15 in), but stroke was increased to 98 mm (3.86 in). This SOHC engine with a 2–barrel carburettor produced 89 hp (66 kW; 90 PS) and 109 lb⋅ft (148 N⋅m). A more fuel-efficient 1–barrel version produced 77 hp (57 kW; 78 PS). Later on, this engine was designated the F.
Applications:
The smallest of the F-family engines is the F6 8-valve SOHC engine. Essentially a de-bored and de-stroked version of the base FE 2.0 with a bore and stroke of 81 mm × 77 mm (3.19 in × 3.03 in). At a compression ratio of 8.6:1, output is 73 hp (54 kW; 74 PS) at 5500 rpm and 89 lb⋅ft (121 N⋅m) at 3500 rpm. It replaced the F/NA 1.6 from the previous generation.
