Split injection Miller cycle with boost decreases knock tendency and increases torque in downsized engine

Green Car Congress

Researchers at Tianjin University in China report that combing split injection to the Miller cycle with boost pressure can effectively decrease the knock tendency and increase the engine torque in a downsized spark-ignition engine. Their paper is published in the journal Fuel. —Wei et al.

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

This trend of increasing demand for higher octane gasoline is likely driven by changes in fuel requirements for light-duty vehicles (LDV) in response to increasing fuel economy standards, which will have widespread implications for future gasoline markets, according to EIA analysts.
