Simulation study finds “Millerizing” the Scuderi split-cycle engine could enable 50% engine downsizing with retention of power and torque, along with reduced fuel consumption

Green Car Congress

Simulation study finds Miller version of Scuderi engine can deliver twice the BMEP as naturally aspirated version, theoretically enabling 50% downsizing while maintaining performance. In a naturally aspirated conventional engine, this would result in a loss of BMEP, but an increase in thermal efficiency. Source: Scuderi.

EIA: trends in downsized engine design leading to increased demand for higher-octane gasoline

Green Car Congress

Further, there is increasing interest among stakeholders in exploring the benefits of higher octane fuels that would lead to higher compression ratios which would lead to more efficient engines and reduced fuel consumption. One significant trend is engine downsizing coupled with turbocharging. Source: U.S. Click to enlarge.
