Title:

FUEL COMPOSITION

Document Type and Number:

Japanese Patent JP2015212384

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide fuel compositions that yield very low soot emissions and low NOx emissions while having high efficiencies and acceptable maximum in-cylinder pressure rise rates over a wide load range when used in an advanced combustion engine environment, especially a combustion engine operating in a partially premixed combustion (PPC) mode.SOLUTION: A fuel composition has a boiling point range of 95 to 440 degrees Fahrenheit, and has (a) a total sum of n-paraffin and naphthene contents of at least 22 volume percent and (b) a RON of about 93 or less. In the fuel, the compression ratio is from about 12:1 to about 16:1. An internal combustion engine used under partially premixed combustion conditions is operated.
