abstract:The Atkinson cycle engine is a type of internal combustion engine invented by James Atkinson in 1882. The Atkinson cycle is designed to provide efficiency at the expense of power density, and is used in some modern hybrid electric applications.
When powered by gasoline, the C-MAX Energi uses the all-new 2.0-liter Atkinson-cycle four-cylinder engine - powerful and fuel efficient and among the most advanced non-turbocharged four-cylinder powertrains Ford has ever offered.
