Enhancement the Octane Number of Sudanese Gasoline (Nile Blend)

A Historical Analysis of the Co-evolution of Gasoline Octane Number and Spark-Ignition Engines

In this work, the authors reviewed engine, vehicle, and fuel data since 1925 to examine the historical and recent coupling of compression ratio and fuel antiknock properties (i.e., octane number) in the U.S. light-duty vehicle market. The analysis identified historical time frames and trends and illustrated how three factors – consumer preferences, technical capabilities, and regulatory legisla...

The Blend Ethanol/Gasoline and Emission of Gases

The Effects of Ethanol–gasoline Blend on Performance and Exhaust Emission Characteristics of Spark Ignition Engines

The effects of unleaded gasoline and unleaded gasoline–ethanol blends on engine performance and pollutant emissions were investigated experimentally in a single cylinder, four-stroke spark-ignition engine with variable engine speeds (2600–3500 rpm). Four different blends on a volume basis were applied. These are E0 (0% ethanol + 100% unleaded gasoline), E3 (3% ethanol + 97% unleaded gasoline), ...

Improved continuous-time model for gasoline blend scheduling

This work introduces a reduced-size continuous-time model for scheduling of gasoline blends. Previously published model has been modified by i) introducing new model features (penalty for deliveries in order to reduce sending material from different product tanks to the same order, product and blender-dependent minimum setup times, maximum delivery rate from component tanks, threshold volume fo...
