| Valvetrain | Direct acting DOHC, 12 valves, continuously variable MIVEC intake valve timing |
The 3A9x family are three cylinder engines which were developed alongside the 4A9x family. They share many similarities with their four cylinder sibling, being an all-aluminum design with chain driven double overhead camshafts, four valves per cylinder (12 in total) and continuously variable MIVEC on the intake camshaft (except for the 1.1 Litre 3A91).
The bore and stroke of each 3A9x model is the same as the corresponding 4A9x model.
The MIVEC used on these engines closes the inlet valves late under light load to reduce pumping losses.
Initially the engine was built at the joint Mitsubishi Daimler-Chrysler facility - MDC Power in Germany from its release in 2003 until 2011 before production moving to Mitsubishi's Kyoto facility from 2012.
