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. of the LDV market by 2025.

SwRI simulations show turbocharged Scuderi Engine could reduce a standard 2011 Nissan Sentras fuel consumption by up to 35% on FTP cycle

Green Car Congress

The Sentra model was simulated through a standardized Federal Test Procedure-75 (FTP-75) drive cycle for each SSC engine design. up to 33% increase in MPG) was achievable with an SSC engine replacing the Sentra’s engine when factoring in fuel cutoff during deceleration and idle in the model.

Concept: Downsized and Supercharged Hybrid Pneumatic Engine for 30%+ Reduction in Fuel Consumption

Green Car Congress

Schematic of downsized and supercharged four-stroke hybrid pneumatic spark injection engine. The reduction in fuel consumption is obtained mainly through enabling the effective use of a heavily downsized engine, rather than from regenerative efficiency. Source: ETH Zürich. Click to enlarge.
