ECONAMIQ: Flexible over-expansion with cylinder deactivation can reduce ICE fuel consumption by up to 20%
Green Car Congress
OCTOBER 29, 2019
By over-expanding into adjacent de-activated cylinders, ECONAMIQ creates an additional power stroke within the existing engine architecture, with a significant thermal efficiency increase and cost savings as a result. Using the virtual simulation environment GT-Power, this cycle is applied to a 4-cylinder SI engine.
