Three-cylinder

edit

F5A

edit

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 the stroke reduced from 66 to 60 mm. Available in various versions with 6, 9, or 12 valves and 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)
  • Max torque: 41–86 N⋅m (4–9 kg⋅m; 30–63 lbf⋅ft)

Applications:

F5B

edit

This 547 cc engine is the successor of the earlier F5A engine, with the bore and stroke size increased to 65 x 55 mm. It was available with 6 or 12-valve SOHC/DOHC head designs. Naturally aspirated and also turbocharged models, with an available intercooler, were on offer. These engines were only used between 1989 and 1990, after which the Japanese government changed the maximum displacement for kei cars up to 660 cc.

  • Max power: 34–64 PS (25–47 kW; 34–63 hp) at 6500 to 7500 rpm
  • Max torque: 42–76 N⋅m (4–8 kg⋅m; 31–56 lbf⋅ft) at 4000 to 6000 rpm

Applications:

F6A

This 657 cc engine was introduced in 1990. Based on the old 550 cc F5B engine, it retains the 65 mm bore, but with new 66 mm stroke size.

  • Max power: 36–64 PS (26–47 kW; 36–63 hp) at 6000 to 7000 rpm
  • Max torque: 50–90 N⋅m (5–9 kg⋅m; 37–66 lbf⋅ft) at 3500 to 4000 rpm

Applications:

F8B

edit

A SOHC 6-valve 796 cc engine, bore and stroke size is 68.5 mm × 72 mm. This engine has never been offered in Japan and was originally intended for export models of the Suzuki Alto. This engine has since become widely available in India, Pakistan, and China, where it has been installed in a wide variety of vehicles.

F6B

edit

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]

  • Max power: 64 PS (47 kW; 63 hp) at 7000 rpm
  • Max torque: 82 N⋅m (8 kg⋅m; 60 lbf⋅ft) at 3500 rpm

Application:

This is a 970 cc, SOHC 8-valve engine version of F engine. The bore and stroke size is 65.5 mm x 72 mm. F10A is also the longest running F engine family. 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.

  • Max power: 40–60 PS (29–44 kW; 39–59 hp) at 5500 rpm
  • Max torque: 62–78 N⋅m (6–8 kg⋅m; 46–58 lbf⋅ft) at 3000–4000 rpm

Applications:

The 970 cc F10A engine as well as 870 cc (62 mm x 72 mm) DA/LJ462 and 1051 cc (65.5 mm x 78 mm) DA/LJ465Q versions are available in China and produced by numerous Suzuki's former business partners such as Jilin, Jiefang, Changan, Changhe or Hafei and used in a wide number of small vehicles, mostly based from Suzuki Carry, Suzuki Alto or even Daihatsu Hijet.

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

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.

The head is much longer than the F10A version, with a three-inch overhang over the gearbox, due to a sensor on the end of the camshaft in place of a traditional distributor, and with a cast aluminium coolant outlet bolted onto the block, consisting of a thermostat, protruding even further.

The FWD F10D sump is different shape and length, the block has differing bolt hole arrangement. The oil pick up pipe and it's mounting points are completely dissimilar on the RWD F10A, and both have different cranks and bearing caps

While the F10A and F10D could bolt to each other's FWD/RWD gearboxes and engine mounts, the F10D occupies more space and would need an updated oil feed system.

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.

Notes

edit
  1. ^ Turbocharged: 8.0 to 9.2, naturally aspirated: 8.7 to 11.0
  2. ^ 550-660 cc: 7500 to 9000 rpm, 800-1100 cc: 6500 to 7000 rpm.
  3. ^ International version of SJ410 Jimny was discontinued in late 1980s, but both Indonesian built Jimny (including Katana, a cheaper 4x2 version of Jimny, introduced in 1989) and Pakistani built Jimny (Potohar) were produced for local market at least until 2006.
  4. ^ Indonesia, Myanmar and Vietnam continued producing Suzuki Carry with F10A engine in the 2000s. After of the discontinuation of Indonesian built ST100 Carry 1.0i in 2009, as of December 2020, Vietnam and Myanmar still producing SK410 Carry with F10A engine.
