Simulation study finds Miller version of Scuderi engine can deliver twice the BMEP as naturally aspirated version, theoretically enabling 50% downsizing while maintaining performance. Applying the Miller cycle to the Scuderi engine (right) entails downsizing of the compression cylinder. Source: Scuderi. Click to enlarge.

Below this GVW the technology has already been acquired by Valeo as a supercharger for cars and light commercial vehicle applications. Unlike a turbocharger, Cobra is not dependent on the exhaust gases flowing to do its work. Earlier post.) The benefits of Cobra to the engine developer and end user depend on the application.

Since this energy loss is primarily thermal in nature and can be attributed to the exhaust, cooling system, and engine and transmission surfaces, Mazda’s R&D team’s central focus is on improving the engine’s thermal efficiency cost-effectively. Extreme compression ratio rather than downsizing. Although downsizing—i.e.,
