Daihatsu E-series engine
The Daihatsu E-series engine is a range of compact three-cylinder, internal combustion piston engines, designed by Daihatsu, which is a subsidiary of Toyota. The petrol-driven series has cast iron engine blocks and aluminum cylinder heads, and are of either SOHC or DOHC design, with belt driven heads.
The E series engine was first presented in the summer of 1985, as the EB, a replacement for the two-cylinder AB engine used in Daihatsu's Kei cars until then. The engine was Daihatsu's second three-cylinder design Originally with two valves per cylinder, four-valve versions later appeared as did turbocharged versions. The engine is quite light, with the original EB-10 weighing in at 60–63 kg (132–139 lb) depending on transmission fitment.
EB-series (550 cc)
The EB-series is a 547 cc (0.55 L) version built in Daihatsu's Osaka plant in Japan, meant for their domestic market range of Kei cars. Bore is 62 mm and stroke is 60.5 mm, with a firing order of 1—2—3. Outputs range between 32 PS (24 kW) to 64 PS (47 kW), the maximum allowed for a Kei car. Power claims for the very earliest Mira/Cuore models are in gross rather than net, which explains slight differences in power ratings for the first few years. This engine has not been exported to any great extent, with Daihatsu's export models usually receiving the larger ED and C-series engines.
The EB-series was only ever available with an SOHC valvetrain and two valves per cylinder, as Daihatsu were late to adopt multi-valve technology for their kei car range. However, the EB was available with an IHI turbocharger and intercooler, originally carburetted but later with fuel injection. This is still the only Kei engine to have reached the 64 PS threshold with only two valves per cylinder. There is also a rare supercharged version developed for the Hijet Pickup, to provide extra low-down torque and allow for an air conditioning unit to be fitted and used even when heavily loaded. This engine was also used for an economy version of the Italian Innocenti Mini, until replaced by the later 660 cc EF engine.

ED-series (850 cc)
The ED-series is a 847 cc (0.85 L) version originally intended for the export versions of the Cuore/Mira. This engine has never been available in the domestic Japanese market. Bore is 66.6 mm and stroke is 81 mm. The ED engine was to undergo a long development as production was later taken over by Malaysia's Perodua, who still produce it in its latest, DVVT form. There was also a short-lived special version for the Swiss markets, where several cantons had tax systems which favoured cars of less than 800 cc. This, the ED-10A, had a two millimeter narrower bore (64.6 x 81 mm) for a displacement of 796 cc.

EF-series (660 cc)
The EF-series is a 659 cc (0.66 L) version designed to replace the EB series engine when kei car regulations changed for 1990. It was first seen in the Daihatsu Mira when it was facelifted in March 1990. The bore is 68 mm (expanded from 62) and stroke is 60.5 mm. Having undergone a long development, a myriad versions of this engine have been developed, and fitted to a multitude of Daihatsu products. Production ended in December 2007, by which time the new KF engine had replaced the EF across the board. The EF was nearly as light as its predecessor, with a 2004 EF-SE clocking in at 68 kg (150 lb) - this with the added weight of modern emissions equipment and fuel injection.

EJ-series (1 litre)
The EJ-series appeared in February 1998. An 81.0 mm stroke and a 72.0 mm bore makes for a total displacement of 989 cc (1.0 L). It is a DOHC, 12-valve inline three-cylinder water-cooled engine. After the Perodua MyVi was redesigned in 2011, it is no longer used in any automotive applications except in Indonesia. The entry level class of Daihatsu Xenia uses EJ-VE engine until now. The engine is equipped with VVT-i and produces 63HP at 5600 rpm and 9.2 kgm of torque in 3600 rpm. Production of the EJ-VE engine (for upright placement) is continued for industrial use in other countries.
