The Suzuki F engine is a series of inline three- and four-cylinder internal combustion petrol engines manufactured by Suzuki Motor Corporation and also licensed by many manufacturers for their automobiles. This engine was Suzuki's first four-stroke car engine when it first appeared in 1977.[1][2]

Three-cylinder[]

F5A[]

The smallest F engine family with 543 cc of displacement, bore and stroke size is 62 mm × 60 mm. The F5A was basically a three-cylinder version of the F8A four-cylinder engine, without the fourth cylinder and reduced stroke size from 67 mm to 60 mm. Available in various versions with 6, 9 or 12-valves SOHC or DOHC head designs, carburettor or fuel injection and naturally aspirated, turbocharged or supercharged.

  • Max power: 28–64 PS (21–47 kW; 28–63 hp)

The 658 cc F6B engine is the smallest four-cylinder engine in the family and also the only one with DOHC 16-valve valvetrain design. This engine is also the only one with turbocharger and intercooler within the four-cylinder variant. The bore and stroke size is 65 mm × 49.6 mm (2.56 in × 1.95 in). This engine shared the same 65 mm bore size of the three-cylinder F6A, although the stroke was shortened to 49.6 mm to keep the displacement nearly the same as the three-cylinder F6A, even with the additional fourth cylinder.[10]

Debuted in 1978 Suzuki SC100, but most of the applications were ceased at least until late 1990s for international market with stricter emission regulation, such as in Europe. In 2005, this engine was upgraded with fuel injection and catalytic converter to meet Euro 2 emission standard for Indonesian market Suzuki Carry 1.0.[11] In 2017, this engine was upgraded again to meet the Euro 4 emission standard for Vietnamese market Suzuki Super Carry.[12] As of December 2020, F10A is still available in Vietnam and Myanmar.

The Suzuki F10D engine is an inline four-cylinder 1.1 L; 64.7 cu in (1,061 cc) engine that was developed in India by Maruti Suzuki for the domestic market. It was debuted in the Maruti Wagon-R in India in 2001. It was briefly installed in Maruti Alto and it was the engine that the first Maruti Zen Estilo came with. This engine is very similar to the three-cylinder F8D 12-valve engine that was optional on the Maruti 800 at the time. The bore and stroke of F10D is the same as that of the smaller sibling and shares quite a few parts like pistons, rings, connecting rods, and valves. The cast-iron engine block is very similar to that of the older 1.0 L (970 cc) F10A engine that powered the earlier Maruti Gypsy and Maruti 1000. Both F10A and F10D shares the same stroke length; but interchangeability of parts between these two engines is limited, and in some cases unknown, with current findings listed below:

Likeness:

F10A/F10D transmission bellhousing bolt patterns and diameters are the same, and it is possible to swap transmissions between A and D engines.

F10A/F10D both have the same engine mounting points threaded into the side of the engine block.

F10A/F10D have identical oil filter mounting points, the extended oil filter housing from the D can be fitted to the A, or the oil filter spigot from the A fitted to the D

F10A/F10D share the same oil pickup tube mounting point, bolt spacing and diameter


Differences:

F10A intake and exhaust manifolds will not fit the F10D engine (or vice versa) due to difference in the cylinder head bolt patterns and port spacing.

F10A oil dipstick tube is located in the centre of the block on the right-hand side, the F10Ds is front mounted on the right hand side with no port drilling in the centre of the block.

The F10D got a contemporary SOHC alloy cylinder head with 4 valves per cylinder and MPFI.[15] The earlier engines made 62 bhp (46.2 kW) and the late model 32-bit ECU raised it to 64 bhp (47.7 kW). It is very respectable performance for naturally aspirated 1.1 L engine. Maruti re-engineered and optimized the F10D after a few years of its introduction. This "low friction engine" as it was called has a revised engine block, lighter crank and revised oil pump.

Maruti announced in September 2009 that the F10D would not meet upcoming Euro 4 emissions norms and was to be phased out in 2010. It was replaced by the new 3- and 4-cylinder K-series engines.
