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 depending on transmission fitment. EB-series (550 cc) The EB-series is a 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 to , 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.

The ED-series had undergone several changes from being carbureted 'ED-10' to 'ED-DE' where the introduction of fuel injected DOHC had been introduced, reviving this newly redesigned engine.
