To provide fuel capable of sufficiently exhibiting engine characteristics of a premixed compressed self-ignition type engine capable of attaining low NOx discharge gas, low fuel cost and high heat efficiency at the same time.
The fuel for premixed compressed self-ignition type engine has the following distillation properties (1) and fulfills the following required conditions (2) and (3). (1) Initial boiling point is <45°C and 50% distillation temperature is ≥30°C and ≤80°C and final boiling point is <120°C. (2) 4×E1+3×E2+2×E3-1×E4-4×E5≥150 [wherein E1 is a fraction having <70°C boiling point; E2 is a fraction having ≥70°C and <100°C boiling point; E3 is a fraction having ≥100°C and <130°C boiling point; E4 is a fraction having ≥130°C and <160°C boiling point; E5 is a fraction (vol.%) having ≥160°C boiling point]. (3) Paraffin content in the fuel is ≥30 vol.%.
