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.

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. Applying the Miller cycle to the Scuderi engine (right) entails downsizing of the compression cylinder. Source: Scuderi. Click to enlarge.

New Delphi 500+ bar GDi system cuts particulates by up to 50% without engine changes

Green Car Congress

Building off its 350 bar GDi (Gasoline Direct Injection) system, Delphi Technologies has developed a 500+ bar GDi system that can reduce particulate emissions by up to 50% without expensive engine re-designs for the majority of applications. The solution is a new, high-efficiency pump designed by Delphi Technologies.
