Hyundai Gamma engine


The Hyundai Gamma engine was introduced in 2006 to replace the existing Hyundai Alpha engine. There are and versions of this engine. The most recent, "clean-sheet" iteration is the 2020 Gamma II which is part of the new Smartstream family, reverting to MPI in lieu of GDI for the non-turbo version, and first debuting in the 2020 Hyundai Accent and Kia Rio and in the 2020 Hyundai Venue, each in the United States. The Gamma II is distinguished by CVVD which is the first introduction of "continuously variable valve duration" allowing control of the total length of time the intake valves are held open. It can apparently run in Atkinson cycle under low loads for additional fuel economy with the ability to shift to Otto cycle on demand due to high loads or extra acceleration.
