ABSTRACT:
The present invention provides a fuel for homogeneous charge compression ignition engines, which can achieve a stable homogeneous charge compression ignition at a higher output. The fuel satisfies the following requirements (1), (2), (3), and (4):(1) certain distillation characteristics between an initial boiling point (IBP): 0° C. or higher and 60° C. or lower; and an end point (EP): 250° C. or higher and 380° C. or lower;(2) research octane number: 62 or greater and 85 or less;(3) density at 15° C.: 0.700 g/cm3or higher and lower than 0.800 g/cm3; and(4) Reid vapor pressure at 37.8° C.: 30 kPa or greater and lower than 65 kPa.
