There are a couple items mentioned in this article that I wanted to discuss. The article: "Atkinson cycle (late-closing intake valves) that sacrifices some low-rpm torque to gain mid-range efficiency. A two-mode variable intake-valve-timing and -lift system provides extra power for acceleration and maximum efficiency during cruising." Has anyone evaluated when the 'two-mode variable intake-valve-timing and -lift system' is putting the ICE in Atkinson cycle? What is the maximum RPM /torque for Atkinson cycle? Minimum RPM? The article: "Recycling cooled exhaust gas (EGR) also reduces consumption" I thought EGR was for reducing NOx, and actually reduced thermal efficiency (increasing consumption). I thought the Clarity used a NOx catalytic converter for NOx reduction.
