Mitsubishi 4B engine

From Wikipedia, the free encyclopedia

The Mitsubishi 4B engine is the newest range of all-alloy straight-4 engines built at Mitsubishi's Japanese "World Engine" powertrain plant in Shiga on the basis of the Global Engine Manufacturing Alliance (GEMA). Although the basic designs of the various engines are the same (engine block), their exact specifications are individually tailored for each partner. All engines developed within this family have aluminum engine block, four valves per cylinder, DOHC camshaft layouts, and MIVEC variable valve timing.
