PURPOSE: A structure for mounting an injector is provided to reduce amount of pollution generated in low speed driving area of an engine. CONSTITUTION: An injector mounting part(22) of a cylinder head is chamber-processed to form an inclined surface(24) with conic shape. The inclined surface is formed during casting process of the cylinder head, or separately processed. The inclined surface of the cylinder head in which a nozzle(32) of an injector(30) is placed is processed to be conically shaped to prevent collision of fuel against the cylinder head when the fuel is injected from a nozzle hole(34) of the injector. Protrusion of the nozzle is about 1.1mm, which is smaller than usual 1.6mm about by 0.5mm. Stable output and pollution quality are allowed in low speed driving area of an engine thereby as fuel injected through the nozzle hole of the injector from colliding against a lower side of the cylinder head, and protrusion of the nozzle is reduced.
