The H-shaped engine comprises parallel left-side and right-side vertical inline piston banks, each having a crankshaft and pistons, a cylinder head, and individual fuel feeds, but sharing a common power transmission system. The selector control actuates a transfer system that prevents simultaneous operation of both engines.

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.

The turbocharged concept allows reaching engine speeds of 6,000 rpm, with a high indicated efficiency of 45% along with clean combustion; power density at 6,000 rpm is 64 kW, with 300 kPa intake pressure. Thus the HCPC range can extend to all engine operating conditions, including very high loads. Tamagna, D., Gentili, R.
