Suzuki F10D engine

Suzuki F10D engine is an inline 4-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 3-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, conrods and valves. The cast-iron engine block is very similar to that of the older F10A 1.0 L (970 cc) 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 not known.

Chronology
SuccessorSuzuki K engine

The F10D got a contemporary SOHC alloy cylinder head with 4 valves per cylinder and MPFI. 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 has announced in September 2009 that the F10D will not meet upcoming Euro 4 emissions norms and will be phased out in 2010. It will be replaced by new K-series 3- and 4-cylinder engines.
