In 2002, the Global Engine Production Alliance was shaped by Hyundai-Kia, Mitsubishi and Chrysler. The 1st engines of the collaboration ended up unveiled in 2004 with output commencing two years later on in 2006. This 2.four-liter gasoline engine 4B12 design shares design and style functions such as distributed gas injection and aluminum 16 valve cylinder head without having hydro compensators together with a number of other distinctive aspects like a sequence driven timing program referred to as MIVEC which has phasing models on both of those intake shafts to lower vibration ensuing from an oil pump balancer unit combined alongside one another for further more advancement resulting in their more recent era index under the identify 4J12.
