Unleaded gasoline constituent for direct injection type gasoline engine inside cylinder

摘要

P To provide an unleaded gasoline composition for a cylinder direct injection type gasoline engine and the gasoline composition reducing an injector deposit of the cylinder direct injection type gasoline engine. PSOLUTION: In the unleaded gasoline composition for the cylinder direct injection type gasoline engine and a distillation amount E120 (vol.%) up to distillation temperature of 120° C and a distillation amount E150 (vol.%) up to 150° C satisfy conditions represented by inequalities (1) E120≤ 75, (2) 25≤ E150-E120≤ 50, and (3) E150≥ 85; 50 vol.% distillation temperature T50 (° C) satisfies inequality (4) 85≤ T50≤ 105, an 8C aromatics content V (C8A) (vol.%), a 9C aromatics content V (C9A) (vol.%), a 10C aromatics content V (C10A) (vol.%), and an ≥ 11C aromatics content V (C11+A) (vol.%) satisfy conditions represented by inequalities (5) 20≤ V (C8A) +V (C9A) +V (C10A) ≤ 45, and (6) V (C11+A) ≤ 2; and a sulfur content is 10 mass ppm or less.
