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.{{Cite web|url=https://www.goo-net.com/magazine/106160.html|title=【名車探訪】 SUZUKI ジムニー(初代)|trans-title=Visiting a famous car, the first generation Suzuki Jimny|language=Japanese|website=www.goo-net.com|date=26 July 2018 }}{{Cite web|url=https://www.globalsuzuki.com/corporate/history/1970.html|title=History of Suzuki - 1970s|website=www.globalsuzuki.com}}

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 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.

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.

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.{{citation | type = brochure | title = Carry 1.0i Pick-Up | language = id | publisher = P.T.

The Suzuki F10D engine is an inline four-cylinder {{convert|1061|cc|L cuin|1|abbr=on|disp=flip}} 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 {{convert|970|cc|L|1|abbr=on|disp=flip}} 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.{{cite web|url=http://www.indiacar.com/roadtest/alto/index1.htm|title=Maruti Suzuki Alto Road test|work=Indiacar|accessdate=January 12, 2010|url-status=dead|archiveurl=https://web.archive.org/web/20100201173529/http://www.indiacar.com/roadtest/alto/index1.htm|archivedate=February 1, 2010}} The earlier engines made {{convert|62|bhp|1|abbr=on}} and the late model 32-bit ECU raised it to {{convert|64|bhp|1|abbr=on}}. 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.
