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) distillation characteristics:
initial boiling point (IBP): 0°C or higher and 60°C or lower;
30 volume percent distillation temperature (T30): 70°C or higher and 130°C or lower;
50 volume percent distillation temperature (T50): 95°C or higher and 200°C or lower;
70 volume percent distillation temperature (T70): 100°C or higher and 280°C or lower;
90 volume percent distillation temperature (T90): 150°C or higher and 330°C or lower;
95 volume percent distillation temperature (T95): 230°C or higher and 360°C or lower; and
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/cm 3 or higher and lower than 0.800 g/cm 3 ; and
(4) Reid vapor pressure at 37.8°C: 30 kPa or greater and lower than 65 kPa.
