| 摘要 |
The present invention provides a fuel capable of controlling the combustion reaction during homogeneous charge compression auto-ignition combustion to improve the engine thermal efficiency. The fuel satisfies specified characteristic requirements relating to: (1) the total content of C5 to C10 normal paraffins; (2) the total content of C6 to C11 aromatic hydrocarbons; (3) the content of olefinic hydrocarbons; (4) the content of oxygenates; (5) the research octane number; (6) the initial boiling point and end point in distillation characteristics; (7) the averaged maximum pressure rise rate of the fuel over continuous 400 cycles; and (8) the averaged IMEP of the fuel over continuous 400 cycles.
